Title: Semiconductor laser device
Inventor: ITOU RIYOUICHI
IPC: H01S5/042
Filed: 1980-01-25
Abstract: PURPOSE:To eliminate the variation in the laser output of a semiconductor laser device due to the alteration in the temperature of the laser device by detecting the variation in the output light of the laser device and controlling the input of a thermoelectric cooling element for controlling the temperature of the laser device according to the detected output. CONSTITUTION:When a semiconductor laser element 1 oscillates, it irradiates laser lights 3, 4. The laser light 3 is utilized as a light source, and the laser light 4 irradiated to the light receiving surface of a photodetector 5 arranged in the vicinity of the element 1. After a signal proportional to the output 4 monitored by the photodetector 5 is amplified by an amplifier 6, it is compared with the standard value to change an electric current supplied from a power supply 7 to a thermoelectric cooling element 12 so as to approach the varied amount of the signal from the standard value to zero. Since the temperature control by the thermoelectric cooling element is rapid in response and has an advantage to lower or raise the environmental temperature according to the polarity of the current, this element 1 can retain the laser output constant even in the environment largely varying the environmetnal temperature.

Title: Optical recording medium and its manufacture
Inventor: HAMADA EMIKO
IPC: G11B7/24047
Filed: 1989-01-14
Abstract: PURPOSE:To obtain reproducing signals comforming to the CD formats by forming such a layer which is deformed by the energy generated by absorption of laser light in a light-absorbing layer, on the side closer to a light-transmitting substrate than to the light-absorbing layer. CONSTITUTION:When the light-absorbing layer 2 is irradiated with laser light, the layer 2 absorbs the light and generates heat, and local increase of pressure is caused by gas or swelling due to melting, evaporation, sublimation, reaction, decomposition or modification of the layer. When the light is focused to irradiated the light-absorbing layer, energy generates and affects the adjacent layers to locally deform them. Thus, optically modified area (pit) is formed, which is similar to a pit formed on the substrate 1 by pressing or other methods. Thereby, the reproducing signals comforming to the CD formats can be obtained.

Abstract: PURPOSE:To improve the shape and dimensional accuracy of a lens by welding a ring-like member to the circumference of a lens forming section on the internal surface of a cap main body while the member is brought into contact with light-transmitting glass. CONSTITUTION:After placing a glass tablet T composed of hard glass plate, etc., on one end side of a cap main body 10, the tablet T is melted by heating the tablet T from the one end of the main body 10.

Title: Electric framed heater for foot warming
Inventor: JITSUKAWA SHIGERU
IPC: F24H3/04
Filed: 1986-01-18
Abstract: PURPOSE:To maintain or change the temperature in an electric framed heater for foot warming depending on whether its temperature is constant or unstable with temperature variation by providing a temperature sensor which makes control of lowering to some extent the inner temperature of the framed heater for foot warming in the state that the air temperature of the air flowing through a wind passage maintains a certain temperature for a certain time and makes control to lower the temperature in the heater step by step repeatedly and finally does not lower the temperature to a temperature lower than a set temperature. CONSTITUTION:It is judged by the control treatment in an outer control controller 9 whether the state of temperature in a temperature sensor 5 keeps a certain temperature or is unstable with varying temperature. For instance, if the temperature inside an electric framed heater for foot warming is constant, control is made to lower the inside temperature somewhat lower than a temperature initially set. Next, when, with the inside temperature lowered, a stable condition continues for a certain time period, control is made again to lower the temperature to a temperature which is a little lower than the present temperature. This procedure is repeated to lower the temperature gradually and when the temperature reaches a limit temperature to which the heater temperature could be lowered, control is made without lowering the temperature repeatedly.

Title: Foaming apparatus
Inventor: TADA TETSUYA
IPC: B05B11/06
Filed: 1980-01-28
Abstract: PURPOSE:To prevent careless or unprepared flow of foam by attaching a rod to close the spray hole of a nozzle and a cap with foam flowing holes to the nozzle fitted as slide-move freely to hook the cap on the seal position and close the spray holes. CONSTITUTION:At the seal position where hook 52 of cap 18 is fit into hook groove 45 and lod 26 closes spray hole 24. When cap 18 is slided to the direction of an arrow and hook 52 is fit into front hook groove 44 while holding projection 58, lod 26 is separated from spray hole 24. When trigger 12 is turned at this foaming position, compressed liquid is flows out from spray hole 24 and flowing spray liquid is dispersed by the collision with lod 26. Since noncollided spray liquid is mixed with the dispersed spray liquid and also sufficient air is mixed with these spray liquid, generated foam flows out from foam flowing hole 30.
