Title: Rotor core for motor
Inventor: WATANABE TAKASHI
IPC: H02K1/26
Filed: 1982-02-18
Abstract: PURPOSE:To improve characteristics of a motor by a construction wherein a rotor core slot is formed with a wedge-like portion at a rotor core slit thereof. CONSTITUTION:A wedge-like portion 113 is formed at a rotor core slit 116 of a rotor core 108 on the side to be cut by a cutting bit 114. Since the wedge-like portion 113 has a larger contact area because of its wedge-like form, the contact resistance between a secondary conductor 109 and the rotor core 108 becomes also larger. Thus, when the secondary conductor 109 is poured, it has no tendency to flow into the wedge-like portion 113 and instead the wedge-like portion 113 is filled with gas 112 generated at the time of pouring, so that a completely vacant space is formed there because of its specific structure. By so doing, it becomes possible to maintain the resistance between the secondary conductors and hence to improve characteristics of the motor.

Title: Electrostatic lens
Inventor: HONDA KAZUHIRO
IPC: H01J37/12
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To provide a small-sized electrostatic lens with a small aberration. SOLUTION: In this electrostatic lens, first, second and third electrodes 1, 2 and 3 are disposed along the optical axis of an electron beam. A voltage introduction terminal 8 is contacted to the second electrode 2. Dummy terminals 20, 21 and 22 are provided on three points on the side wall of the third electrode 3 through insulating materials 17, 18 and 19. The dummy terminals 20, 21 and 22 are approximately in the same shape as the voltage introduction terminal 8. The voltage introduction terminal 8 and the dummy terminal 21 are symmetrically disposed crossing the optical axis, and the dummy terminals 20 and 22 are symmetrically disposed crossing the optical axis. Thereby, the same electric field as the electric field generated near the voltage introduction terminal 8 can be created near the dummy terminals 20, 21 and 22.  As a result, a rotationally symmetric (symmetry four times) electric field as the electric field of a electrostatic lens can be maintained, the aberration of a lens can be reduced and the axial shift of an electron beam can be significantly reduced.

Title: Output circuit device with high dielectric strength
Inventor: SAKASHITA HIROHIKO
IPC: H03F3/42
Filed: 1982-02-16
Abstract: PURPOSE:To constitute an output stage with high dielectric strength which uses transistors (TR) whose VCBO and VCEO are low, by using a voltage dividing circuit and an emitter follower circuit in combination and suppressing VCE  applied to individual TRs low. CONSTITUTION:A signal inputted from an input terminal 1 is current-amplified by a TR2. On the other hand, a voltage a half as high as the sum of the voltage applied to the input terminal 1 and a power voltage VCC is applied to the base of a TR3 through resistance 4 and 5. The emitter voltage of the TR3 is VBE (about 0.7V) less than the base voltage. Therefore, the collector voltage of the TR2 is suppressed to the voltage obtained by dividing the sum of the input voltage and power voltage by the resistances 4 and 5. In this case, when the resistances 4 and 5 have nearly equal values, a maximum voltage regarding the VCE of those two TRs 2 and 3 is a half as high as VCC and the rated voltages of the individual TRs are reduced to a half as high as that of a conventional circuit which uses one TR.

Title: Method and device for treating liquid
Inventor: JIYATSUKU KENESU IBOTSUTO
IPC: C02F1/48
Filed: 1992-02-10
Abstract: The present invention relates to a method and apparatus for treating electrically conductive fluid. Positive (1) and negative (2) electrodes of electrically conductive materials having different electrochemical potentials are spaced apart and electrically isolated from one another so that the only electroconductive connection that develops an electrochemical potential between the electrodes (1,2) is established by fluid to be treated flowing between the electrodes. Such fluid is therefore ionized which will both prevent the precipitation of solids from the fluid which would tend to form a scale on the inner surface of piping through which the fluid flows, and aid in the removal of a previously formed scale. A third electrode (3) is also provided so as to be electroconductively connected with the positive electrode (1) but electrically isolated from the negative electrode (2). Therefore, the third electrode (3) will release metal ions into the fluid. These ions will inhibit the release of compounds into the fluid having a principal element that is the same as that of the metal ions released by the electrode (3). In such a way, the fluid can also be treated to inhibit a particular compound, to which the fluid might be exposed, from dissolving into the fluid. <IMAGE>

Title: Mold cooling device
Inventor: SAITOU TOSHIKATSU
IPC: B22D21/02
Filed: 1979-02-27
Abstract: PURPOSE: To ease the putting the mold into and out from the mold cooling device and perform powerfuly cooling and directional solidification by disposing a pipe part which leads inert gas to the position which does not hamper various operations and constituting the nozzle part separated from the pipe part movably together with the mold table.  
     CONSTITUTION: A nozzle part 2 is fixed onto a mold table 1 and a mold 3 is placed on this. The table 1 is moved upward and is poured with molten metal, after which it is again lowered and inert gas is blown from the pipe part 4 through a nozzle. In this case, the nozzle part 2 and table 1 as well as pipe part 4 will not hamper their movements with each other. The outlet of the pipe and the inlet of the nozzle are simply in proximity and a gap exists therebetween but the gas hardly leaks from this gap. Hence, the greater portion of the gas may be applied to the mold through the nozzle.

Abstract: PURPOSE: To maximize an image pickup area without a special operation by performing an operation to the side of a wide end for prescribed plural steps from a telescopic to the wide field end for which an image pickup magnification state can be set. CONSTITUTION: A controller 132 reads the output of a rotary encoder 113 and compares it with the read value of a previous time. When both values are equal, since the encoder 113 is not operated, an operation is ended. When they are different, a rotation direction is discriminated and the variable of the encoder 113 is updated. When it is defined as right rotation, first, the states of zoom, focus and diaphragm operation specifying members 114, 115 and 116 are read to the controller 112 and what is to be operated is decided. A motor 104 is moved to the telescopic side for two steps at the time of a zoom operation 114, the motor 105 is driven near the step at the time of a focus operation 115 and a photometric target is increased by two from a present value at the time of a diaphragm operation 116. Also, when the encoder 113 is in left rotation, the operations are inversed.

Filed: 1988-02-05
Abstract: PURPOSE:To cancel the change of the low band signal component of an analog input signal by providing a correcting current generating means and offsetting a switching current generated to a C-MOS.A/D converter by means of a mean switching current. CONSTITUTION:At the time of m-number of comparing circuits, a clock frequency fs, a synthetic capacity Cs of a capacitor C, and a mean voltage VRM, the mean voltage of the switching current is made into an expression I. From a dummy comparing circuit 20, a switching current Is' expressed by an expression II is outputted. Voltages between the drains and sources of transistors Q5 and Q6 are made into Io+Is' and (1+m)(Io+Is'), respectively, and (1+m)Io is supplied from a constant current source S3. Consequently, an output current from a circuit 10 is made into I=-Is'(1+m), and an expression III is obtained from the expression II. Consequently, when a mean current value Isa of the expression I and the current Is' to flow in the circuit 20 are made to flow out from a coupling capacitor Cc, the current of the expression III is made to flow in from the circuit 10. As a result, an expression IV is made, and the switching currents to flow to (m+1)-number of comparing circuits can be offset by the current I.

Abstract: PROBLEM TO BE SOLVED: To provide a gas purge box which can shorten the time the gas concentration of a cassette storing chamber reaches a target value and lessen the gas flow. SOLUTION: A gas purge box 11 is divided into a right and a left chamber 16A, 16B by a partition wall 15. The chambers 16A and 16B can be opened and closed by doors 12A and 12B separately.
