Patent JP-S62272759-A (JP)
Title: Electrophotographic recorder
Inventor: ISHIHARA SHUJI
IPC: B41J3/00
Filed: 1986-05-21
Abstract: PURPOSE:To obtain a correct density gradation by exposing by blinking for plural times or stopping the respective light emitting elements of a light emitting element array with an electrostatic latent image holder being temporarily stopping for every one line of subscanning, thereafter moving the electrostatic latent image holder to the following line of subscanning and stopping it to expose in a similar manner. CONSTITUTION:During the time when the electrostatic latent image holder 1 is stopping, the light emitting elements 3 are made emit light for times corresponding to the gradations of respective dots. After ending the exposing of one line, the holder 1 is moved in the direction of subscanning to the place of the following line then stopped to expose in a similar manner. For example, the time necessary for one line of scanning T is divided into four equal parts, and during the time when the holder 1 is stopping, the elements are made emit light respetively for four, three, two, and one times of, said time division respectively for dots 1, 2, 3, and 4. But, for a dot 5, the elements are not made emit. By thus varying the times of light emitting corresponding to the gradation of the dots to be printed, the amount of electrostatic charges in the holder 1 is made variable corresponding to respective dots. Therefore, since the amount of sticking developing powder varies, the five degrees of density gradation are obtained.

Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To prevent sudden change in the temperature of a crystal oscillator by providing an insulating block with satisfactory heat conduction which is supported by penetrating two lead members protruding outwardly from a metallic base and a heat generating body fitted to the insulating block. SOLUTION: The insulating block 32 is constituted of the material of SiC ceramics with high electric insulation performance and thermal conductivity and holes 32a through which the two lead members 31 pass are formed. The block 32 is formed in a cylindrical form and a disk form by considering that a heat line 33 is wound around it. A semiconductor element 34 assisting heating and controlling the conduction power of the heater line 33 is arranged at the center of the block 32 for equalizing the temperature distribution of the crystal oscillator 37. A thermosensitive element S is arranged in an appropriate position in the block 32 so that the temperature becomes equal to that of the oscillator 37.  The start time of a unit using the crystal oscillator is considerably shortened by conducting heat from a heat source to the oscillator 37 in short time by the shortest route through the block 32, the lead parts 31 and supporters 36.

Title: Multi-room type air-conditioner
Inventor: ABE SHINICHI
IPC: F24F11/02
Filed: 1993-05-19
Abstract: PURPOSE:To prevent an abrupt rise of a high pressure side pressure of a refrigerating cycle by making the valve travel of a motor-driven expansion valve corresponding to a stopped room unit larger than that of the valve immediately before it is stopped when any of a plurality of room units which are driven to heat is stopped. CONSTITUTION:When two room units are operated to heat, high pressure gas refrigerant from a compressor 1 is fed from a four-way valve 2 to room side heat exchangers 6, 7 via a tube 8 to motor-driven expansion valves 4, 5 to be reduced under pressure. When the operation of one of the two room units 9 is stopped, a load to the compressor 1 is instantaneously increased, and the high pressure side pressure of a refrigerating cycle is abruptly raised. Then, the valve 4 to the stopped room unit 9 is opened for a predetermined time with its valve travel made larger than that of the valve immediately before stopping. Thus, more refrigerant flows to reduce the load to the compressor 1, thereby preventing abrupt rise of the high pressure side pressure of the cycle.
