Abstract: PURPOSE:To prevent the oxidation of end faces of a high-output semiconductor laser and to elongate the life of the laser, by depositing a multilayer dielectric film having a low reflectivity also on the front end face of the laser. CONSTITUTION:End-face protective films covering both end faces of a resonator are each made of a multilayer dielectric film consisting of at least two different types of dielectric layers deposited alternately: first dielectric layers having a lower refractivity and second dielectric layers having a higher refractivity. Further, at least one of the multilayer dielectric films covering one end face is formed out of a light transmitting film having a reflectivity of 30% or less.

Title: Life monitoring system
Inventor: SASAKI TOSHINORI
IPC: H04B3/46
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To make the occurrence of malfunction to be difficult by permitting a product operation situation detection means to directly detect the operation situation of respective electrical fittings. SOLUTION: In the product operation situation detection part 1, CCPU, IC and a transmission part are mounted on a substrate and CPU detects the types of products and the operation situation. The detection part 1 is connected with centralized management parts 2 provided for respective houses through intra- house electric wirings 7. The management part 2 receives signals from the detection part 1 on the respective electric fittings 8 in a reception part and stores them in an incorporated memory. Even if a request from a life monitor part 3 does not exist, the stored signal is transmitted to the monitor part 3 through a telephone line 12 from incorporated CPU. The monitor part 3 one- dimensionally manages the signals from the management parts 2 provided for the respective houses.  Thus, a life situation can remotely be monitored without changing life environment and the occurrence of malfunction becomes difficult. Then, an inexpensive life monitor system can be obtained.

IPC: F15B15/14
Filed: 1995-03-09
Abstract: PURPOSE: To improve the dimensional accuracy of a piston, reduce the starting pressure in a cylinder and to reduce the leakage of pressurized fluid from a piston packing. CONSTITUTION: A rodless cylinder received in a cylinder tube 1 is provided with a piston 14 slid in the cylinder tube 1 by fluid pressure.

Filed: 1983-03-26
Abstract: PURPOSE:To prevent natural oscillation of a stylus holder from approaching a half of horizontal synchronizing frequency, i.e. 7875Hz even if peripheral temp. is changed, and to prevent a picture image from disturbance by dividing an arm point part into two parts and holdig and fixing the stylus holder between the divided arm point parts. CONSTITUTION:The point part of the arm 7 is constituted by opposing two divided parts 7A having U-shaped sections. The right and left sides, a part of the upper surface and the lower surface of the stylus holder 8 are held by the two divided parts 7A. Since at least both the sides of the stylus holder 8 are held by the arm 7 in said constitution, the rigidity of the stylus holder 8 is increased. Consequently, the natural oscillation of the stylus holder 8 fitted to the two divided parts 7A is not almost changed by the peripheral temperature change. Therefore, the natural oscillation of the stylus holder 8 does not approach 7875Hz even if the peripheral temperature is changed.

Filed: 1989-03-02
Abstract: PURPOSE: To suppress light reflection by the (substrate)-(photo resist) interface to an allowable level by using a dyestuff system having a high absorption coefficient at the peak wavelength of i-line light. CONSTITUTION: In a PCM system 8, a substrate 10 having irregular parts 11 on its upper surface 12 is covered with a lower layer 14 and a dyestuff 13 capable of absorbing i-line light and another dyestuff 15 capable of absorbing ultraviolet light are dissolved in the lower layer 14. There is an interface 18 between the lower layer 14 and an upper layer 16 and i-line light 20 is made incident on the upper layer 16 and any adverse effect due to the reflection of light by the (substrate 10)-(lower resist layer 14) interface 12A is eliminated by the dyestuff 13.  When the exposure energy intensity is about 400mJ/cm<2> , a sufficient concn. of the dyestuff 13 that actually absorbs the i-line light is obtained in the lower layer 14 and the absorbance at a 365±5mμ wavelength becomes sufficiently high and accordingly, about 80% of the incident light on the lower layer 14 is absorbed in it by only once passing the i-line light through the lower layer 14. Thus, the reflection by the interface 12A is reduced and the resolution with respect to line width in the upper layer 16 is improved.
