Filed: 1980-07-31
Abstract: PURPOSE:To simplify the circuit constitution, by picking up either one of normal signal systems at output side, through the discrimination if two system signals are both normal or either one of them is normal by means of the output state of two comparators. CONSTITUTION:The output of comparators COMP1, COMP2 is (11) when two signal systems A, B are both normal, (01) when the signal system A only is normal and (10) when the signal system B only is normal. In the latch circuit consisting of gates G1, G2, the G1 outputs ''1'' when the input is (01) to switch a selector switch S1 to the signal system A and to output the signal to the output terminal OUT. The G2 outputs ''1'' when the input is (10), the S1 is selected to the signal system B to output the signal. The signal system A or B is outputted at the output terminal OUT according to the selection of the selector switch S2 when the input is (11).

Title: Semiconductor laser element
Inventor: SUYAMA NAOHIRO
IPC: H01S5/00
Filed: 1987-04-28
Abstract: PURPOSE:To make a clad layer of a semiconductor laser thinner without deterioration of laser characteristics and to improve the productivity and yield by making the structure near the active layer of the semiconductor laser a structure wherein the exudation of light from the active layer to the clad layer is very little. CONSTITUTION:Light guide layers 4, 6 which are made a junction with both adjacent layers are interposed between an active layer 5 and clad layers 3, 7 by gradually changing a mixed crystal ratio in the range between the active layer 5 and the clad layers 3, 7 and the thickness of the clad layers 3, 7 is set 0.5 mum or less. Since the exudation of light to the clad layers 3, 7 is made very little by the graded refractive index distribution type light guide layers 4, 6, the absorption loss by a substrate or a cap layer is very little even if the thickness of the clad layer is made thinner and characteristics are not deteriorated even if the thickness is made 0.5 mum or less. This enables obtaining the improvement of productivity without the deterioration of the characteristics of a laser element and simultaneously, the improvement of the characteristics according to the reduction of the density of detects can also be expected.

Title: Inverter apparatus
Inventor: YOKOI OSAMU
IPC: H02M7/48
Filed: 1994-05-20
Abstract: PURPOSE:To detect the current flowing through an AC motor correctly by detecting and storing the leaking current component flowing through the ground from a wiring before the driving of the AC motor beforehand, and subtracting the leaking current component with respect to the detected value outputted at the driving of the AC motor. CONSTITUTION:Before an AC motor 5 is driven, all positive-side elements and all negative-side elements of an inverter 4 are alternately conducted at a specified frequency for the constant time. The positive and negative potentials are applied on the winding of the AC motor 5 by this conduction, but all phases become the same potential. The current does not flow through the AC motor 5. However, the leaking current flows through the stray capacitance of a wiring. The leakage current is detected with a current detecting circuit 7. When the AC motor 5 is driven, the current detecting circuit 7 detects and outputs the leaking current in addition to the current flowing through the AC motor 5. The output of a leaking-current memory circuit 8 is substracted with a subtracting circuit 9 with respect to the above described output. Thus, the current flowing through the AC motor 5 can be correctly detected.

Abstract: PURPOSE: To inhibit the adhesion of dusts onto the paint-applied surface of a strip, by arranging a filter in a circulating line formed inside a furnace, and spraying an in-oven atmosphere clarified by the filter onto the surface of the running strip.  
     CONSTITUTION: A metal strip 2, onto which a desired paint is applied, is let run through an oven 1, while an in-oven atmosphere is sprayed onto the strip 2 to dry and bake the applied paint. A part of the in-oven atmosphere is taken out through a solvent-inhaling hole 8 and introduced into an incinerator. The resultant combustion exhaust gas is fed through a feed hole 9 into the oven 1.

Title: Prism for detecting raindrop
Inventor: ISHINO HIROTSUGU
IPC: B29D11/00
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of bubbles in a resin prism for detecting raindrop and, at the same time, to improve the adhesive strength of the prism. SOLUTION: Since the adhesive surface 10a of a prism for detecting raindrop is treated by the UV-O3 cleaning method, the surface 10a is modified to its molecular structure and the polarity of the surface 10a becomes larger as compared with that of the surface 10a before treatment. Namely, for example, an adhesive layer (hatched circles shown in the figure) having a polarity larger than that on the opposite side of the adhesive surface 10a is formed. Therefore, even when an inexpensive resin prism 10 is used, the occurrence of bubbles in the prism can be prevented under a high-temperature condition, because an adhesive is sufficiently fitted to the prism 10. In addition, the adhesive strength of the prism 10 can be improved, because it is not required to form a plurality of adhesive parts as in the case of the conventional device.
