Title: Method and device for switching cooling/heating mode in absorption type water cooling and heating machine
Inventor: MACHIZAWA KENJI
IPC: F25B15/00
Filed: 1999-09-29
Abstract: PROBLEM TO BE SOLVED: To prevent the self-boiling of bromide lithium solution, reserved in an absorber, upon switching the heating mode operation of a bromide lithium absorption type water cooling and heating machine into the cooling mode operation of the same. SOLUTION: A conventional bromide lithium absorption type water cooling and heating machine is provided with a heat exchanger 21 for cooling bromide lithium solution (a radiator 26 can be provided). The bromide lithium solution (shown by parallel oblique lines in a diagram), whose temperature is raised during heating mode operation, is cooled upon the switching operation of heating into cooling by guiding the same into the heat exchanger 21 for cooling the solution. According to this cooling, the self-boiling of the bromide lithium solution can be prevented.

Title: Photo detector
Inventor: JIYOOJI RICHIYAADO ANTERU
IPC: G01J1/02
Filed: 1988-11-01
Abstract: PURPOSE: To obtain an efficient photodetector by applying a bias voltage to a diode and producing a photovoltaic signal corresponding an incident light signal and then amplifying the photovoltaic signal through an amplifier. CONSTITUTION: An inner barrier 10 is formed between an N type InGaAs layer and an InP layer of a PIN diode. The barrier 10 blocks holes 11, generated in the InGaAs layer by a light, from migrating to the outside of a detector. Consequently, photovoltaic power is not generated under unbiased state. When a reverse bias is applied, an air region spreads into the InGaAs layer and the height of barrier decreases greatly. A bias voltage of 10V, for example, is then applied selectively to the PIN diode 12 by closing a switch 15. A diode applied with a bias voltage is thereby enabled to respond to an incident light signal. Consequently, a photovoltaic output code is generated and amplified through an amplifier 13.

IPC: B41M5/155
Filed: 1984-12-25
Abstract: PURPOSE:To obtain excellent fluidity with a low viscosity, by adding heavy calcium carbonate previously ground by a wet-type process to an inorganic color developer.

Filed: 1990-10-15
Abstract: PURPOSE:To increase an operating speed by making the voltage of a power source supplied to a transistor with which an output terminal and a drain electrode are connected higher than the voltage of the power source supplied to the transistors except for the transistor and making the gate length of the transistor longer than those of the other transistors.

However, a VDD 2 101 on 5.0V which is higher than a VDD 11 on 3.3V is impressed to the sources of Tr 116 and 117, so that the drain currents of the Tr 116 and 117 can be larger than the drain currents of the Tr 11-15. and 21-25 with the same gate width, and therefore, the capacities added to the output terminals can be charged at a high speed. Thus, the dependency of the load capacities of a logic circuit can be sharply improved, and an integrated circuit device can be operated at the high speed.

Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To facilitate the arrival of the correcting position of a feed saddle, regardless of an electronical decoupling of an operating part from the driving device of the feed saddle. SOLUTION: An electronical correcting device to correct the position of a feed saddle 6 to feed a material to be cut has a rotating pulse generator 21 including a switch 20 which can be operated manually, and an evaluation unit 23 controlled by the rotating pulse generator 21, and the evaluation unit 23 controls the driving of the feed saddle 6.

The starting of the rotating pulse generator 21 is released at the second change-over position of the switch 20.  In order to facilitate the arrival of the correcting position of the feed saddle 6, regardless of the decoupling of a manual wheel from the driving device of the feed saddle 6, the operation speed of the feed saddle 6 is reproduced on the display panel 11 of the device, directly or indirectly, and as to the direction, when the position of the feed saddle 6 is corrected.

Title: Thrust deflection controller
Inventor: ONO MICHINARI
IPC: F42B10/66
Filed: 1984-12-27
Abstract: PURPOSE:To make a simple and durable constitution as well as to make an actuator small in size by controlling deflection thrust according to the degree of comformity between deflection ports and a rotary ring port of the thrust deflection controller of a flying object. CONSTITUTION:Exhaust gas burnt inside a rocket motor 1 is injected from a nozzle 2, and when the port 6 of a rotary ring 5 does not conform with deflection ports 7a-7e, it does not generate crosswise thrust, but when they conform with one another, a part of exhaust gas generates crosswise thrust through the rotary ring port 6 and the deflection ports 7a-7e. Therefore, in order to acquire crosswise thrust of desired direction, the rotary ring 5 is rotated by a DC motor 4 installed inside a box (A) through a rotary power transmission section 8 so that the rotary ring port 6 is conformed with any desired positioned deflection ports 7a-7e, with the magnitude of crosswise thrust to be controlled by the degree of conformity between the rotary ring port 6 and the deflection ports 7a-7e. This rotation does not need strong torque, and thus, a simple constitution is possible, and durability is improved.
