Title: Washer nozzle
Inventor: SUZUKI TAKAHIRO
IPC: B05B1/24
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a washer nozzle capable of effectively melting the snow and ice covering a nozzle body and properly injecting washing liquid to a glass plate even in winter. SOLUTION: A space 16 is formed in the side opposite to the washing liquid injecting direction in a PTC heater 15. Owing to this space 16, most of the heat generated by the PTC heater 15 is transmitted to a portion in the side of an injection hole 14 more than a portion in the inner side of a vehicle hood 2 in the nozzle body 11. Accordingly, the snow and ice covering the nozzle body 11 can effectively be melted, making it possible to properly injecting liquid to glass plates even in winter eliminating the necessity of enlarging the heater and batteries.

Abstract: PURPOSE:To eliminate the residue by previously ion implanting a contacting hole forming position through a contacting hole formed at a resist film on an insulating layer, and then reactively ion etching to open a hole. CONSTITUTION:Oxygen ions are implanted to a contacting hole forming portion to implant oxygen atoms into the first and second insulating layers 9, 10 to form the state that ashing feasibly occurs, polymer ion coupling for forming the layer 10 by the ion implantation is disconnected to form the state that an etching feasibly occurs. In this case, since oxygen ions are implanted through the hole 12 to the layer 10, when a reactive ion etching is executed with mixture gas of CF4 and O2 in the same manner as the conventional method, the removal of the resist by the radical of the CF4 and O2 is accelerated by the operation of the oxygen, readily performed, and etching residue is not retained.

Title: Pyrheliometer for air conditioning of automobile
Inventor: TERADA TOMOJI
IPC: G01J1/02
Filed: 1991-03-07
Abstract: PURPOSE:To obtain an attractive pyrheliometer by compressing the total height of a cover without lowering the sensitivity to the light of the low height. CONSTITUTION:An extinction part 4 filled above a photoelectric converting element 2 absorbs, reflects or scatters the penetrating light thereby to attenuate the light. Particularly, since the extinction part 4 is located immediately above the photoelectric converting element 2, the rate when the incident light upon the photoelectric converting element 2 passes through the part 4 is increased when the sun height is high, and therefore, the sensitivity of the photoelectric converting element 2 is decreased. Meanwhile, when the sun height is low, the light entering the photoelectric converting element 2 slantwise penetrates the peripheral part, of a cover 3 slantwise without passing through the extinction part 4. Therefore, the rate of the light reaching the photoelectric converting element 2 is increased, thus improving the sensitivity of the element S2. An optically transmissive filling part 5 reduces the reflection of light at the inner surface of the cover 3, and increases the amount of light penetrating into the protecting cover 3.
