Title: Light source of semiconductor laser
Inventor: TATENO KIMIO
IPC: G02B27/00
Filed: 1991-09-13
Abstract: PURPOSE:To handle a semiconductor laser having an astigmatism as a point light source which is not affected by adverse influence of the astigmatism by disposing a parallel flat surface plate obliquely in a luminous flux having an astigmatism, to be sent from the laser, and integrating the laser with the plate. CONSTITUTION:Optical beams having astigmatisms of different converging points in a direction parallel to a connecting surface and a direction perpendicular to the direction, irradiate from a semiconductor laser 1. A parallel flat surface plate 3 having a thickness (d) and a refractive index (n), is disposed obliquely in an optical beam to be sent front the laser 1. An astigmatism difference A generated by the plate 3 is given by a formula DELTA. The astigmatism generated by the laser 1 can be corrected by selectively setting the thickness (d), the refractive index (n), and an incident angle (inclining angle) (i) of the plate 3 based on the formula. Here, a light source in which the astigmatism is corrected, by integrating the laser 1 with the plate 3, is obtained by moving an angle regulating plate 6 as indicated by arrows.

Title: Light and heat conversion type heat mode image receiving material and recording material
Inventor: MAEJIMA KATSUMI
IPC: B41M5/50
Filed: 1992-09-02
Abstract: PURPOSE:To make it possible to firmly adhere image receiving material and recording material uniformly in a short time in a small space with a device low in cost and prevent trouble which occurs at conveying by setting surface roughness or waviness of an image receiving face to a specified value with a light and heat conversion type heat mode image receiving material. CONSTITUTION:A value Ra of an ink layer of a recording material 3 or a surface roughness of an image receiving material 4 is 0.4-0.01, but 0.3-0.05 is desirable. When the value Ra exceeds 0.4, adhesive property deteriorates, transfer sensitivity lowers, dot reproducibility of transfer image deteriorates, and color turbidity occurs. Making it below 0.01 is difficult from the viewpoint of production and fog due to pressure transfer will easily occur. On the other hand, the waviness of the surface (irregularity on the surface observed at an interval of 0.1.-several mm) is 2mum or less. It may be larger comparing with the surface roughness. However, when it becomes 2mum or more, the adhesive property deteriorates as well, although it depends on rigidity of the image receiving material 4 and the recording material 3. When vacuum adhesion is to be performed, degree of adhesion changes dependently on pressure-reducing time. The shorter the pressure-reducing time is, the more preferable it is.

Title: Process input and output device
Inventor: UEDA SHINJI
IPC: G06F13/14
Filed: 1985-10-21
Abstract: PURPOSE:To shorten a processing time when a large quantity of information is transferred form peripheral devices by providing a connection switch circuit for peripheral devices to a process input/output device. CONSTITUTION:A process line connection control circuit 8 initializes a control circuit from a central processing unit 1 via a control circuit reset line 9. Then a process line of a peripheral device 3a is connected to a data line 4. An input/ output control line 6 changes its state every time the information is transferred between the unit 1 and a process input/output device 2. Thus the state change of the line 6 is detected within the circuit 8 and the connection commands fed to the process line connection circuits 7a-7h are successively shifted in the order of circuits 7a 7b 7c for each state change of the line 6. Thus it is possible to transmit the information to each peripheral device without analyzing nor connecting data by the program stored in the unit 1.

Title: Heat pump type air conditioner
Inventor: HATTA HIROSHI
IPC: F25B1/00
Filed: 1987-09-18
Abstract: PURPOSE: To prevent refrigerating machine oil from flowing out to a refrigerating cycle by setting a flow control valve provided in oil return piping coupling an oil separator and the suction tube of a compressor in the opening direction at the time of starting operation thereby keeping a constant oil level in the compressor. CONSTITUTION: At the time of starting operation, an operation start detecting means 10b detects starting operation of a compressor 1 through a variable frequency power supply 9. Means 10c for determining the opening of a flow control valve then determines a larger opening than that at normal operation and means 19d for controlling flow control valve controls the opening of a flow control valve for a longer time as compared with normal operation. Since the quantity of refrigerating machine oil flowing out from an oil separator 2 to the compressor 1 increases, a constant oil level can be kept in the compressor and the reliability thereof can be enhanced. Furthermore, flow-out of refrigerating machine oil to the refrigerating cycle causing decrease of cooling/heating capacity can be suppressed.
