Title: Changeover switch allowing integration
Inventor: BERUNHARUTO TSUOIYAA
IPC: H03K17/567
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To obtain the changeover switch which is low in the cost for its circuit and has low internal resistance and high dielectric strength. SOLUTION: This switch has a 1st switching means B which has one terminal connected to a positive supply potential VP and the other connected to a load terminal L and an (n) channel type DMOS field effect transistor F which forms a 2nd switching means. Then the source terminal is connected to a reference potential M, the drain terminal is connected to one load terminal L, and the gate terminal is supplied with the reference potential M for generating a cutoff switching state and a control potential SP which is more positive than the reference potential M for the generation of a conductive switching state.  Further, its ON state resistance is made small so that a source-drain voltage drop by a maximum source-drain current is lower than the base-emitter threshold voltage of a parasitic bipolar transistor B formed of the bulk and drain of the field effect transistor F and a substrate terminal SUB, and the switching states of both the switching means B and F are generated reversely to each other.

Title: Formation of color image
Inventor: SATOU TADAHISA
IPC: C03C25/10
Filed: 1983-03-18
Abstract: PURPOSE:To form a magenta image good in color reproducibility by developing a silver halide photosensitive material in the presence of a specified coupler and/ or a polymer or copolymer coupler derived from a vinyl monomer having this specified part in the molecule with a developing soln. contg. aromatic primary amine. CONSTITUTION:A silver halide photosensitive material is developed with a developing soln. contg. aromatic primary amine in the presence of a coupler of the formula (R1, R2 are each H or a substitute, and X is H or a group releasable by coupling reaction), or a polymer or copolymer coupler derived from a vinyl monomer having said part of the formula in the molecule. As a result, the subabsorption of 5-pyrazolone type coupler near 430nm can be eliminated, and color reproducibility, color developing speed, and max. color density can be improved. The coupler can be converted into a so-called 2-equiv. type by introducing a releasable group to the active site of coupling, and therefore, a magenta image capable of cutting down an amt. of silver to be used can be formed.

Title: Speed controller of motor
Inventor: HOSHINO AKIHIKO
IPC: H02P29/00
Filed: 1984-03-12
Abstract: PURPOSE:To obtain a stable and equal response even if the inertial moment of a drive system varies by correcting a gain in response to the variation in the inertial moment of the system. CONSTITUTION:A mechanical constant stored in advance in a memory 7 is led to a correcting gain calculator 8 in response to a signal from a coupling variation pattern detector 6 for detecting the coupled state of the first and second couplers 3a, 3b. The calculator 8 corrects the gain of a speed deviation signal in response to the constant output from the memory 7, and leads the signal corrected in the gain to a speed controller 11. The controller 11 controls a thyristor converter 5 which supplies the armature current of a DC motor 1 so that the speed deviation signal corrected in the gain becomes zero while compensating the variation in the power source current.

Title: Recording and reproducing device
Inventor: YAGISAWA TOSHIHIRO
IPC: G06F21/10
Filed: 1990-02-28
Abstract: PURPOSE:To eliminate the need for the addition of a redundancy signal into a main signal by setting the recording enable state when a code comprising initial prescribed bits is coincident with a copy enable code or not is discriminated at recording and both the codes are coincident and setting the recording disable state when dissidence. CONSTITUTION:An enable signal addition circuit 178 as a copy enable code addition means adds a copy enable code to a head of a reproduced main signal at the start of normal reproduction. Then a CPU 171 being a discrimination means discriminates whether or not the code comprising the first prescribed bits is coincident with the copy enable code at the recording and when both the codes are coincident as the result of discrimination, the CPU being a recording control means sets the mode into the recording enable state and when dissident, the CPU brings the mode into the recording disable state. Thus, it is not required to add a redundant signal in the main signal.

Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To provide multiple heat pump type air conditioner which can maintain a proper operation in the heating operation. SOLUTION: During the heating operation, when the pressure of a delivery piping of a constant speed rotary compressor 2 exceeds a specified value, a liquid line solenoid valve 7 is closed to bring the capacity (endothermic quantity) of an outdoor heat exchanger 4 as evaporator down to zero and a hot gas bypass valve 11 of a hot gas bypass circuit 13 is opened to reduce the amount of a refrigerant which should flows into a room unit 20. Then, a liquid refrigerant bypass valve 14 of a liquid refrigerant bypass circuit 16 is opened to restrict the amount of the refrigerant with a capillary tube 15 so that a suction pressure of the constant speed rotary compressor 2 is lowered to prevent a rise in the delivery temperature of the compressor.  Thus, an input value of the constant speed rotary compressor 2 is lowered to be kept below the degree of heat radiation of the room unit 20 in operation.

Title: Heat accumulating vessel by use of metal hydride
Inventor: UEDA KEISUKE
IPC: F28D20/00
Filed: 1981-03-31
Abstract: PURPOSE:To make it possible to improve the thermal efficiency of the titled heat accumulating vessel by a method wherein hydrogen gas passages are so provided in the metal retaining space that they come into contact with a heat exchange surface of the vessel. CONSTITUTION:Each of the hydrogen gas passages 5 provided in the metal retaining space 4 in a heat accumulating vessel is formed by hemp cords or stranded copper wires and the hydrogen gas flows through the passages 5 from a space adjacent to the connecting ports of the passages 5. Consequently, the  hydrogen gas enters a metallic particle layer formed in the metal retaining space  4. In this case, the reaction between the metallic particle and the hydrogen gas takes place very quickly at positions near the passages 5, that is, the position near the heat exchange surface 1 of the heat accumulating vessel so that the reaction heat is quickly transferred to a heat exchange fluid flowing through a passage 2 to thereby improve the thermal efficiency of the heat accumulating vessel.
