Patent JP-S6225477-A (JP)
Title: Laser oscillator
Inventor: USUI AKIRA
IPC: H01S3/04
Filed: 1985-07-26
Abstract: PURPOSE:To prevent a member such as a reflecting mirror from damaging by providing a branch tube and a leakage water detector for detecting the moisture dropped to the tube in a laser gas circulating passage. CONSTITUTION:When the supply of coolant is forgotten and coolant is supplied from the midway of operation, a discharge tube 1 is already at high temperature, and accordingly cracked to invade the coolant to be mixed with laser gas 5. When this gas is arrived at a branch tube 15, the mixed coolant is dropped to the bottom of the tube 15. The dropped water is detected by a leakage water detector 14 to stop operating of a laser oscillator, to operate valves of an inlet 12 and an outlet 13 of the coolant, thereby stopping supply of the coolant and exhausting the coolant. With this construction, the coolant leakage is rapidly detected to prevent a member such as a reflecting mirror from damaging.

Filed: 1983-09-05
Abstract: PURPOSE:To reduce thickness of internal diameter of secondary split winding bobbin by separating the primary coil from a secondary high voltage winding part and forming iron core with the ferrite core having resistivity of several MOMEGA-cm. CONSTITUTION:A thickness of internal diameter (t) of secondary split bobbin 2 is set to 3mm. or less from combination with an iron core 1. The primary coil 5 is wound separately so that it is not located near the internal diameter part of secondary high voltage winding of the bobbin 2. Moreover, a ferrite core having resistivity of several MOMEGA-cm is used as the iron core 1 which is internally in contact with the bobbin 2 and the iron core 1 is protected from terminating to the ground potential. Thereby, thickness t of bobbin 2 can be reduced and as a result coil can be reduced in size. Moreover, the bobbin is formed with uniform thickness and can be formed easily.

Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a pack for a semiconductor device which can be produced in stable processes having high heat-radiating performance and nigh reliability. SOLUTION: A metallic substrate of a three-layer structure having a metal plate with an insulating body on the plate and a copper foil on the insulating body is used.

Title: Facsimile equipment
Inventor: KATO TETSUYA
IPC: B41J29/46
Filed: 1997-06-07
Abstract: PROBLEM TO BE SOLVED: To prevent contents of information received in the state of having possibility to generate a printing defect from being incapable of being understanding. SOLUTION: When a detected voltage Voff at a photodetector in the off-state of an LED(light-emitting diode) is lower than 1.5 V, the state of too strong external light to discriminate paper jamming or empty ink can be judged, so that the message of 'reception in progress ...' is displayed on a liquid crystal display without starting printing operation. When a start switch is operated, formed printing is started (S1-S9). Afterwards, the received data are erased from are reception memory for the first time when a reset command is issued (S11-S13). Even when the presence of a printing defect is discriminated as a result of printing defect discrimination due to a check mark, received data are held as well.
