Title: Logic circuit
Inventor: TANIMURA TOSHIAKI
IPC: H03K19/00
Filed: 1987-06-08
Abstract: PURPOSE:To suppress the change in an output level due to the fluctuation of a level shift voltage by connecting a FET forming a constant current circuit in parallel with a FET forming a differential circuit. CONSTITUTION:In making a current flowing to a resistor 16 constant, the constant current flowing to a FET 34 is fluctuated, e.g., increased, then the constant current flowing to a FET 46 is increased similarly. In this case, the current flowing to resistors 38, 40 is the subtraction of the constant current flowing to the FET 46 from the current flowing to the resistor 16 and smaller by the current flowing to the FET 46 and the voltage drop across the resistor 40 is decreased, then the potential at a point P is increased. When the constant current flowing to the FET 34 is increased, the level shift level by diodes 28-32 is increased by the increase and the level shift of the diodes 28-32 due to the increase in the constant current flowing to the FET 34 by the increase in the potential at the point P is cancelled, resulting in suppressing the output level change. When the current flowing to the FET 34 is smaller, since the potential at a point P is lowered similarly, the change in the output level is suppressed.

Title: Device for automatically mixing disinfectant with city water
Inventor: MATSUMURA YOSHIHIDE
IPC: C02F1/50
Filed: 1992-04-20
Abstract: PURPOSE:To use liquid disinfectant easily dilluted at required concentration and to attain an effective result a sanitary aspect without trouble such as calculation for preparing the dilluted liquid and replacement of disinfectant by mixing liquid disinfectant automatically diluted at specified concentration with city water when it is allowed to flow out and allowing the mixture to flow out. CONSTITUTION:Detection of flow rate is performed by a gear type flow rate sensor 2 in the inside of an ejector 1. The detected result is outputted to a controlling circuit. A feed pump of liquid disinfectant must faithfully execute the feed rate by a command of the controlling circuit. Therefore the liquid chemical of accurate quantity is fed. A tubular pump is used so that the rotary part of the pump is not directly touched to the liquid chemical. Further the required concentration is set by an operation switch. The correlation of both the flow rate of water and the rpm of the motor for the pump is previously stored in the controlling circuit. When city water starts to flow, the flow rate is measured by the flow rate sensor 2. The pump of disinfectant is turned ON after measurement and rotated only at the set concentration of the operation switch and the calculated result of flow rate and stopped. thereafter it is repeatedly performed.

Title: Torque detecting method and winding torque detecting device
Inventor: KATAOKA AKIRA
IPC: G01L3/14
Filed: 1983-08-06
Abstract: PURPOSE:To monitor winding torque in the vicinity of a winding shaft, by obtaining the transmitting force in the direction of a common tangential line between the tips of the teeth of two gears from the measured value of a load meter when power is transmitted to a measuring gear and a driving gear for said gear, and computing the transmission torque or the amount of change thereof. CONSTITUTION:A shaft 1a of a measuring gear 1 is directly or indirectly supported through a load meter 3 such as a load cell so that the movement in the direction crossing a common central line C of the measuring gear and a driving gear 2 is controlled. When power for both gears 1 and 2 are transmitted, a transmitting force F in the common tangential direction between the tips of the teeth of both gears 1 and 2 is obtained from the detected value (f) of the load meter 3. Based on the force F, transmission torque 7 or the amount of change thereof is computed.

Title: Semiconductor light emitting device
Inventor: NAKAJIMA YASUO
IPC: H01S5/00
Filed: 1985-06-28
Abstract: PURPOSE:To expand the transmitting band of optical fiber without using another optical filter, by providing a dielectric multilayer film mirror on the light emitting surface of a light emitting diode. CONSTITUTION:When a forward direction voltage is applied, electrons and holes are injected in an active layer 5 and confined. Light is efficiently emitted here. The light, which is emitted in the active layer 5, is made to pass a transparent clad layer 6, where band gap is larger than that of the active layer 5. The light is taken out through a dielectric multilayer film mirror 11 comprising high refractive-index material layers 9 having a thickness of 1/4 wavelength and low refractive index material layers 10 having a thickness of 1/4 wavelength. At this time, the dielectric multilayer mirror 11 functions as an optical bandpass filter so as to transmit only the light having constant wavelengths for a narrow band. The band of the transmitted light becomes narrower as the number of both layers 9 and 10 in the dielectric multilayer film mirror 11 increases. Therefore, even if the frequency band of the light transmitted through a clad layer 6 is broad, the spectral width can be controlled to the narrow value by the dielectric multilayer film 11.

Title: Control system for flash emission
Inventor: TSUNEKAWA TOKUICHI
IPC: G03B7/16
Filed: 1981-09-11
Abstract: PURPOSE:To prevent deterioration in picture information due to a noise during the triggering of flash emission by starting to store picture information after the flash emission is triggered for flash image pickup. CONSTITUTION:When an image pickup start switch is turned on at time t1, a trigger pulse is generated at a trigger terminal TR. While a terminal ICG has a high level, photoelectric conversion and storage parts SA1-SAn are cleared through clear gates FA1-FAn, but when the terminal ICG is inverted to a low level at time t2, the storage of picture information is started and the dimming circuit of a flash device starts operation. Thus, the flash device is triggered when image-pickup elements are cleared, thereby eliminating an influence of a noise during the triggering.

In correspondence to the push-down of an index switch key 3 (or 4), the number of the steps for the index character to be displayed in the prescribed number of the rows, which is defined in advance, for the index part 1 is switched to the arbitrary number of the steps from the number, which corresponds to the number of the rows defined in advance, of the steps to one step. Then, the number of the rows is increased and decreased respectively for the index part 1 and data part 2 and the data in the maximum number of the steps are displayed in the data part 2. Thus, it is not necessary to define the number of the steps again when the number of the steps is changed for the index part 1. Then, the index character easily is observed and the large quantity of the data is displayed. Further, the operability is extremely improved.
