Title: Fuel injection valve for diesel engine
Inventor: IRIE YASUTAKA
IPC: F02M61/10
Filed: 1983-06-17
Abstract: PURPOSE:To secure good spray and injection directions at the whole driving range as well as to improve the capacity of combustion, by installig such an injection group as being opened or closed automatically by means of fuel injection pressure and making fuel injectable over the whole driving range, while installing another injection group which spouts the fuel to a high load range alone. CONSTITUTION:Fuel is led into a fuel reserve well 8 via a passage 7 and with fuel oil pressure, a first needle valve 4 is pushed up against the energizing force of a first needle valve spring 6, then flows in a nozzle chamber 21 by way of a first seat part 4a and gets spouted out of a first nozzle hole 1a. At this time, at a high load range, the fuel oil pressure of the nozzle chamber 21 is higher than the calve opening pressure of a second needle valve 14 so that this valve 14 is pushed up against the energizing force of a second needle valve spring 16 whereby the fuel is spouted as well from a second nozzle hole 1b via a second seat part 14a. And, in a low load range, fluid pressure is made to act on a fluid chamber 20 by means of each of valve on-off pressure controlling devices 31-41, controlling the valve opening pressure of the second needle valve 14, and the fuel is also spouted out of the second nozzle hole 1b at every constant injection frequency.

Title: Measurement of contact angle
Inventor: HERUMUTSUTO SHIYUNAIDAA
IPC: G01N13/02
Filed: 1989-04-28
Abstract: PURPOSE: To measure the contact angle accurately by taking advantage of the fact that a predetermined geometrical relationship is present between the contact angle γ and the angle δ between partial beams reflected, respectively, on the flat surface of a solid and the surface of a liquid. CONSTITUTION: A test liquid, i.e., a water droplet 12, is placed on the surface of a solid 10, e.g. a silicon wafer. A laser beam 16 is directed toward an interface line 14 between the water droplet 12 and the surface 10 and reflected while being separated into two partial beams 20, 22. The beam 22 functions as a measuring beam. An angle δ corresponds to the surface 10 and a beam image 24 and formed between the interface region of beam 22 starting from the interface line 14. The angle δ has a predetermined geometrical relationship with a contact angle γ determined by a tangent 34 and observed on a scale 38. Consequently, the contact angle γcan be determined according to a predetermined expression.

Title: Transmission and reception circuit for data transmission
Inventor: NISHIMURA SHINJI
IPC: H04L5/16
Filed: 1984-05-30
Abstract: PURPOSE:To obtain an inexpensive transmission/reception circuit which transfers data through a short-distance transmission line at a low speed, by using just several units of transistors with no compensation needed for waveform distortions. CONSTITUTION:Transistors TrQ1-Q4 constitute a BTL type transmission circuit, and TrQ1 and Q4 are turned on with TrQ2 and Q3 turned off respectively with the transmission signal given from a logical circuit CC for control of transmission. Then a forward current flows to the primary side of a pulse transformer PT, and the ''+'' codes are transmitted via terminals T3 and T4 of the secondary side. While the ''-'' codes are transmitted when the TrQ1 and Q4 are turned off with the TrQ2 and Q3 turned on respectively. Thus the transmission is possible for a double-current binary code. Then the transmission of a ternary code is possible by turning off all TrQ1-Q4. A TrQ5 is turned on when an input code is fetched via the PT and an end T1 has a higher potential than the other end T2. Then the variation of the collector potential of the TrQ5 is fetched by a logical circuit CC. If the T1 has a lower potential than the T2, the variation of the collector potential of a TrQ6 is fetched by the circuit CC. In case the ternary code is received, the TrQ5 is separated from the TrQ6 and the variations of collector potentials of both TrQs are fetched independently by the circuit CC.

Title: Preparation of semiconductor device
Inventor: SASAKI NOBUO
IPC: H01L21/02
Filed: 1982-06-23
Abstract: PURPOSE:To eliminate mis-processing of automatic processing apparatus in the wafer process utilizing a transparent insulating substrate by applying a photo- shielding resist film including dyes as a pre-treatment in the photo-process. CONSTITUTION:A silicon Si epitaxial layer 11, a photo shielding resist film 12, a patterning resist film 13 are sequentially applied to a sapphire plate 10. The film 12 and patterning resist film must be in the same photosensitivity, namely, they must be negative or positive. If the resist film includes dyes, a resolution is deteriorated but pattern accuracy is restricted by the film 13, resulting in no problem. Thereby, if a wafer is composed of and SOS substrate which allows transmission of light, mis-processing due to incorrect detection by photo sensor can be prevented even if a wafer exists.
