Title: Insulated gate bipolar transistor
Inventor: NISHIURA AKIRA
IPC: H01L29/78
Filed: 1990-05-25
Abstract: PURPOSE:To enable a bipolar transistor to carry out a high speed switching operation without increasing it in conduction resistance by a method wherein a fourth region is composed of a deep part whose base is distant from a collector electrode contact surface and a second conductivity type shallow part low in impurity concentration. CONSTITUTION:A P layer (fourth region) 8 is composed of a shallow P layer 81 and deep P layers 82. The layer 81 sandwiched between the layers 82 is periodically formed in band, and when electrons stored in an N<-> layer 1 penetrate the layers 82, the correspondent holes are injected into the layer 1 from the layers 82 when a bipolar transistor is turned ON, and as a barrier is provided between the layer 81 and the layer 1, the injection of holes from the layers 82 into the layer 1 is accelerated. The surface impurity concentration of the layer 82 is set much lower than that of the layer 81,whereby holes are restrained from being injected into the layer 1 from the layer 81 so as not to make the stored carriers excessive. As a PN junction formed between the layers 81 and 1 can be further lessened in junction potential, carriers can be more effectively discharged when a bipolar transistor is turned OFF. In result, a bipolar transistor can be improved in a high speed switching operation keeping low in conduction resistance.

Title: Thyristor converter
Inventor: ITO KATSURO
IPC: H02H7/12
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To prevent damage to a thyristor, if a forward voltage has been applied only to the arm of a thyristor valve failed in turning-off, by giving a gate pulse and turning it on. SOLUTION: At the same time with the turning-off of a thyristor valve 2v, an arm short circuit occurs to the thyristor valve 2u, if a faulty current exceeds a detection level of a level detector 8, it is outputted as a gate block signal GB2 from a control protection equipment 5 to a gate pulse generator device 4, and resets a flip-flop 11 via OR circuit 19 and OR circuit 13. Thereafter, a failure current is cut off once, and if a period from the application of a reverse voltage to the application of a forward voltage to the thyristor valve 2v is longer than a set point T1 at on-delay 15, then the output of on-delay 15 becomes 1, so that the flip-flop 12 is reset. Thus, even though a voltage is applied to the thyristor valve 2v and a FV signal is detected at that point in time, no gate pulse is outputted and the thyristor valve 2v becomes a turn-off state.

Abstract: PURPOSE:To apply repetitively a glass master disk by forming the recessing/projecting grooves for signals and tracks on the master disk with a photoresist and modifyng the resist layer into an insoluble matter through a heating process for solid junction. CONSTITUTION:A resist layer 2 is formed on a cleansed glass master disk 1 for production of a master stamper of an optical disk, etc. Then recessing/projecting grooves for signals and track grooves are formed on the disk 1 through exposure and development, and a remaining resist layer 6 is heated up to >=120 deg.C to secure the solid junction between the disk 1 and the layer 6. Thus the resist layer is insoluble to a resist solution and remains on the disk 1 with no destruction in the subsequent releasing process of a metal layer. Thus the disk 1 can be washed for reuse. Then the 1st and 2nd metallic layers 3 and 4 are formed on the disk 1 including the layer 6 and then released to obtain a master stamper 5. In such a way, the disk 1 is washed and used repetitively.

Title: Gyroscopic two-wheeled vehicle stably standing even at rest
Inventor: SATOU TSUTOMU
IPC: B62D37/06
Filed: 1979-10-24
Abstract: PURPOSE:To enable a two-wheeled vehicle to stably stand even at rest, by mounting a gyromotor and a gyroscope on the body of the two-wheeled vehicle and electrically coupling a vehicle body inclination detector and a gyroscope support frame  control motor to each other. CONSTITUTION:A signal proportional to the inclination angle theta1 of a vehicle body 4 is supplied from a vehicle body inclination detector 6 to an amplifier 10 to cause an electrical current to flow through a control motor 3. This motor 3 applies a turning force to tilt a gyroscope shaft 7 to accelerate the change in an angle theta2. Reaction to the acceleration works in a direction to decrease the inclination theta1 of the vehicle body 4. Signals are thus transmitted among the inclination detector 6, the amplifier 10, the control motor 3, a gyroscope 1 and the vehicle body 4 so that influences are sequentially exerted and feedbacked. This results in keeping the stability of the vehicle body 4.

Abstract: PURPOSE:To miniaturize, to lighten weight and to reduce the cost by permitting a first transmitting type hologram arranged in parallel to have a plane wave whose generating wavelength is shorter than reproducing wavelength and permitting a second transmitting type hologram to have a spherical wave whose generating wavelength is longer than the reproducing wavelength. CONSTITUTION:The first transmitting type hologram 21 arranged in parallel has the plane wave whose generating wavelength is shorter than the reproducing wavelength and a second transmitting type hologram 22 has the spherical wave whose generating wavelength is longer than the reproducing wavelength. Then, diffracted light from the fist transmitting type hologram 21 is made incident on the second transmitting type hologram 22. Therefore, since two holograms are generated by the plane wave and the spherical wave, an image which has sufficient view point is obtained without using a lens. Thus, a device is miniaturized, lighten in weight and the cost is reduced.

Title: Automatic working machine and method of high productivity executing cyclic work process in which machining and translation are combined
Inventor: MISHIERU KOKIYAARU
IPC: B23Q39/04
Filed: 1983-07-26
Abstract: A method of, and apparatus for automatically machining work pieces, wherein a plurality of single spindle units are fixedly attached to a support, and the work pieces are maneuvered in front of the work units by a translatable table. The number of single spindle work units is determined by the formula 2N-1, wherein N is the number of machining operations to be performed on each work piece. As such, there is an odd number of work units thereby creating a central unit which carrys out the last machining operation to be performed in the work piece. The axes of the work units are precisely equally spaced from one another, and this spacing equals the spacing between the work pieces. The apparatus is cyclically operated so that a plurality of work pieces can be worked on simultaneously by individual work units and a new work piece can be loaded when the machining operation is completed on a previously loaded work piece.

IPC: B60T7/12
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To aim at the simplification of a system in terms of structure while a brake surely appliable in assisting braking force whenever it is so judged that this braking force is insufficient. SOLUTION: In time of a braking force insufficient tendency, a first on-off valve 25 is set up in a cutoff position 11 and a pump 10 is driven, whereby an assist force regulating valve 13 comes to an operational state. In brief, a control chamber 22 is made into a hermetically sealed state. In addition, master cylinder pressure Pm out of a master cylinder connecting port 15 is made to go up due to discharge pressure in the pump 10. With this pressure rise, an auxiliary pressure piston 20 is moved downward and a valve part 20a is seated on a valve seat 18. Thereafter, since an effective pressure receiving surface by the valve part 20a and the valve seat 18 at the master cylinder side is larger than that by the valve part 20a and the valve seat 18 at the brake cylinder side, fluid pressure in the master cylinder is fed to a brake cylinder 7 after being intensified. Therefore, braking force assisting control takes place, so that a brake is surely applied even in time of a braking force insufficient tendency.

Title: Vertical magnetic recorder
Inventor: FUKUDA TATSUO
IPC: G11B17/32
Filed: 1983-07-27
Abstract: PURPOSE:To perform recording/reproducing with high efficiency by securing the approximation or a contact between a vertical recording medium and the 1st magnetic pole by means of the sucking force produced at the tips of the 2nd and 3rd magnetic poles to carry out writing/reading. CONSTITUTION:The energization detecting windings 71 and 72 are wound around the 2nd and 3rd magnetic poles 53 and 55 and connected in series. The DC currents I1 of the same direction flow to both windings 71 and 72, and the magnetic fields of the same direction are produced at the poles 53 and 55. The magnetic fields produced from windings 71 and 72 are set opposite to each other at a main magnetic pole 1 and offset with each other. Thus the pole 51 is not magnetized. As a result, tips 54 and 56 of the pole 51 attract a recording medium 1 to have a contact or approximation and therefore a contact or approximation is secured between the medium 1 and the tip 52 of the pole 51. In such a way, the contact can be freely controlled between the medium 1 and a head. Thus, the recording and reproducing are performed with high efficiency.

Abstract: PURPOSE:To form a latent image having a high image quality on a photosensitive body by providing an optical path adjusting mirror on a lens plate of an image forming device in which lenses and image element arrays are arranged such that they correspond to each other so as to accurately form an image by irradiation of a light to be emitted from a light emitting diode element on the surface of the photosensitive body through the lenses. CONSTITUTION:An optical path adjusting mirror 7 is attached to upper parts of a pair of support bodies 6 through an adhesive in a state that it is provided at a lens plate 3. The mirror 7 changes an optical path for light from a light emitting diode element 2a which has penetrated lenses 4 by 5-80 deg. and substantially prolongs the focal length of the lens 4. As the focal length of the lens 4 is substantially prolonged with the change of the optical path by the mirror 7, even when some positional deviations are produced in the distance between the plate 3 and a photosensitive body 5 and in placing position of a light emitting diode element array 2 on a plate 1, the light to be emitted from the light emitting diode element 2a is accurately formed into an image on the photosensitive body 5. As a result, a clear and accurate latent image can be formed on the photosensitive body 5.

Abstract: PURPOSE:To realize efficient communication with simple constitution by comparing the output value of a transmitting shift register with the output value of a receiver and inhibiting a transmitting clock from being applied to the transmitting shift register unless said output values are equal to each other. CONSTITUTION:If a collision occurs, a communication controller 1' has priority because its transmitted data and received data are the same and a communication controller 1 disconnects a control line 102 by a switch 12 so that the transmitting clock is not applied to the transmitting shift register 13 because the transmitted data and received data are different at the 3rd bit b3 and also holds the output of a comparator 16 by a latch device 15 to stop the transmission, thereby only receiving the 4th bit b4 and succeeding bits. When a packet is normal, the controller 11 of the communication controller 1 transmits an ACK signal which indicates that the packet is received normally to the communication controller 1' and transmits the received packet to a terminal device 2 through a communication circuit 2. Then, the packet whose transmission is interrupted owing to said collision is reset similarly to the 1st transmission.
