Title: Noise removing circuit
Inventor: KATOU TOSHIYUKI
IPC: H04B1/10
Filed: 1981-04-22
Abstract: PURPOSE:To remove noises caused by external illumination, by making an envelope of the peak voltage while the peak value of the pulse input signal is held, and outputting the difference between the signal obtained by fetching the AC component in the envelope and the input pulse. CONSTITUTION:If lights coming from outside illumination, etc., exist when a pulse light is generated from a luminescent device and a pulse-like photodetecting signal 2 is generated by receiving the light with a photodetector, the photodetecting signal is modulated and becomes a modulated signal MW. When the signal MW is inputted into a peak holding circuit 1, the circuit 1 fetches only the envelope of the signal MW and outputs a signal EW. Since the signal EW passes through the circuit 1, there is no lag between the phase of the signal EW and that of the signal 2. When the signal EW is passed through an HPF 3, only the AC component of the signal EW is fetched and the component becomes a signal HW. The signals HW and MW are inputted into a subtractor 4 and an output signal 5 of the difference is outputted. In this way, the output signal 5 in which noises caused by lights coming from outside are removed and which is not modulated is obtained.

Title: Forming method for fluorescent screen of color picture tube
Inventor: IZUMI AKIYA
IPC: H01J9/227
Filed: 1978-05-24
Abstract: PURPOSE: To shorten greatly exposure time by equalizing the integration quantity of a light source at each point when carrying out exposure while the light source is reciprocated in the longer-axis direction of the slot of a shadow mask.  
     CONSTITUTION: To form a fluorescent screen with a black matrix on the inner surface of a face plate, exposure is done while the light source is reciprocated in the longer-axis direction of the slot of a shadow mask. If the exposure time is longer than the driving period of the light source at this time, the driving speed is changed to make the exposure time longer than the driving period by an integer. When the exposure time is shorter than the driving period, on the other hand, the driving speed is set with the exposure time made half as long as the driving period, and while the exposure start is synchronized with the driving time, the drive start from the lowermost or uppermost point and ends at the uppermost or lowermost point. Consequently, even when the exposure time is shortened greatly, a black matrix screen of high quality can be obtained as well as a long-exposure-time case.

Title: Head supporter for double side flexible disk drive
Inventor: KUMAKURA TAKESHI
IPC: G11B17/32
Filed: 1989-03-14
Abstract: PURPOSE:To support an arm perpendicularly to a disk by press-contacting a folded part of a tip of a torsional spring in contact onto the arm with a tilt. CONSTITUTION:A folded part 11a of a torsional spring 11 is press-contacted onto an arm 4 with a tilt. Even when there is a slide to a contact part between the arm 4 and the spring 11, a friction resistance is reduced and the arm 4 is supported in a direction perpendicularly to a face of a flexible disk 12. A 2nd head slider 6 depresses a 1st head slider 2 via the disk 12 with a pressing force of a gimbal spring 7. The force of the spring 11 from a slider 6 is larger than a force from the disk 12 and a slider 2 and the arm 4 is supported in a direction perpendicularly to a face of the disk 12 at the recording and reproduction with a stopper 8a of a sub frame 8. The deflection quantity of the spring 7 is decided at a position of the arm 4 in the direction perpendicular to the face of the disk 12 and the pressing force of the slider 6 onto the disk 12 is decided. Thus, the arm is kept supported perpendicularly onto the disk.

Title: Electronic watch
Inventor: NAKASAKI YASUTAKA
IPC: G04C10/04
Filed: 1978-05-22
Abstract: PURPOSE:To inform a user accurately of the end of the lifetime of a battery irrespec tive of the kinds of a watch by stopping the watch, when the battery voltage is lowered, so that the display is instantly fixed. CONSTITUTION:When the voltage of a battery 6 is higher than that of a reference voltage generator 8, no signal is generated from a voltage comparator 7. As a result, a time measuring mechanism 3 and a display mechanism 4 operate as a normal watch assembly. On the other hand, when the voltage of the battery 6 becomes lower that of the generator 8, signals are supplied from the comparator 7 to a counter 5 and the watch 3 so that the mechanism 3 is stopped and that the mechanism 4 fixes the display at that instant.

Title: Rice cooking jar
Inventor: OKUNO TOMIO
IPC: A47J27/00
Filed: 1990-03-12
Abstract: PURPOSE:To stably cook rice to get gruel by providing a rice gruel cooking control program for executing the heating by switching suitably lowered power and large power, and migrating it to a steaming process, when a prescribed time elapses. CONSTITUTION:When rice cooking to get gruel is selected as a rice cooking menu, and a start key switch 13e is turned on and the rice gruel cooking control is started, water is warmed a little for a prescribed time by the timer control and rice is allowed to absorb enough water. Subsequently, a full electric conduction is executed to a rice cooking heater 6 so as to become the maximum power. Whether its temperature is <100 deg.C or not, and in the case of <100 deg.C, the full electric conduction to the rice cooking heater 6 is continued, and cooking-up is executed without executing a 'go' number decision executed by the regular rice cooking control. In the case a temperature falls to <100 deg.C, the full electric conduction is executed to the rice cooking heater 6 and it is heated, and in the case of >=100 deg.C, heating is continued by lowering the heating power. Whether (t) seconds (for instance, 1600 seconds) elapse or not is decided by time counting by a timer, and in the case of not elapsing, this operation is repeated. When (t) seconds elapse, rice cooking to get gruel is finished and migrated to a steaming process.

Title: Load transferrer
Inventor: HATSUTA MORIAKI
IPC: B65G13/00
Filed: 1988-03-17
Abstract: PURPOSE:To give a deflection corrective function to a load transferrer by setting up a pair of taper rollers, having taper tips themselves opposed to each other, in parallel with a plural pair to a center line of the transfer direction and thereby constituting a transfer roller, in the transferrer for a warehouse or the like. CONSTITUTION:Plural pairs of taper rollers 7, 7 having their small diametral sides opposed to each other are set up symmetrically in a center line 6-6 in the transfer direction, thereby forming a transfer roller group. These paired rollers 7, 7 are connected freely at each center part by a universal joint 9, being connected to a drive mechanism, thereby constituting a transfer device 13. Then, one bus bar at the upper side of the taper roller 7 should be set in horizontality or make the roller tip side lower. With this constitution, since a part moves the remoter than a load center line, the speedier, a load is transferred as moving in direction toward the center all the time. Consequently, even if deflection occurs, it converges on the transfer center line 6. Thus, any deflection is automatically controllable.

Title: Non volatile semiconductor memory
Inventor: MIYAGAWA TADASHI
IPC: H01L29/792
Filed: 1987-03-17
Abstract: PURPOSE:To prevent over-erasing, and to obviate the deterioration of character istics on rewriting by adjusting the quantity of electrons (the potential of a floating gate) extracted from the floating gate on erasing in a nonvolatile semi conductor memory. CONSTITUTION:In operation on erasing, an erasing gate 11 or a drain 15 is brought to high potential, and a gate 12 for supplying electrons or a source 16 is brought to ground potential. When erasing operation is started, electrons in a floating gate 13 are extracted to a high potential section for erasing and erasing operation makes progress and the state of over-erasing is brought, the potential of the floating gate 13 rises. When the potential of the floating gate 13 is elevated to a certain potential or more, the electric fields of the floating gate 13 and ground potential for supplying electrons are raised, tunnel currents are flowed, the floating gate 13 is fed with electrons, and the potential of the floating gate 13 is lowered. Consequently, the potential of the floating gate 13 is brought to fixed potential by the balance of extracted electrons and supplied electrons. Accordingly, the abnormal over-erasing state is inhibited, and program characteristics are stabilized even in rewriting.

IPC: G11B20/18
Filed: 1985-03-28
Abstract: PURPOSE:To stably detect for a high-speed change of a pickup and a change in a disk reflectivity by using the wave crest value of an ordinary FM record signal itself as the comparison reference of the wave crest value of the FM record signal detecting a dropout signal. CONSTITUTION:A comparator 7 compares the wave crest value of an input FW record signal M with the upper limit while a comparator 8 compares it with the lower limit side. The direct current component of the signal M is cut by a capacitor C1 and the resulting signal is introduced into a noninverting input terminal of the comparator 8 and an inverting terminal of the comparator 7. C5 and a resistor R4 make up an upper limit side wave crest value holding circuit, and applied with the divided voltage of R5, R6 of the signal M. C6 and R7 make up a lower limit side wave crest value holding circuit and applied with the same divided voltage. In such a manner, dropout can be detected stably even though the signal M is lowered by changes in the laser output, changes in disk reflectivity or high speed movement of the pickup.

Filed: 1991-03-27
Abstract: PURPOSE:To enhance the brightness to a part requiring illumination and prevent the radiation of light to an unnecessary part by radiating the omnidirectional light emitted from a lamp only in a specified direction by a reflecting plate. CONSTITUTION:A reflecting plate 10 is disposed on one side part of a lamp 1, and its lower end is mounted on the cylinder part upper end of a fixing device 2. The reflecting plate 10 interrupts the radiation of the light of the lamp 1 in an unnecessary direction and reflects the light only in a necessary direction.
