Title: Optical deflector, optical scanner and information reader
Inventor: EGUCHI SHIN
IPC: G02B5/18
Filed: 1994-03-18
Abstract: PURPOSE:To obtain a novel optical deflector which is capable of electrically controlling a deflection angle. CONSTITUTION:This optical deflector 1 is constituted by arranging a pair of transparent glass plates 4, 4 provided with transparent electrodes 2 and oriented films 3 on their one-side surfaces so as to face each other and inserting liquid crystals 5 between these glass plates 4, 4. A driving circuit 6 is so connected that an AC voltage or DC voltage is impressed to the transparent electrodes 2, 2. Parallel fringes appear in the liquid crystals 5 when the voltage is applied between the transparent electrodes 2, 2. These parallel fringes function as diffraction gratings. Then, diffracted light appears on an exit side when light is made incident on the optical deflector 1. The light is eventually deflected if the diffracted light is utilized as exit light. The pitch of the parallel fringes changes and the changing of the diffraction angle is possible if the magnitude of the applied voltage is changed and, therefore, the electrical control of the deflection angle is possible.

Title: Ink drop injection type recording device
Inventor: ATSUMI SHIROU
IPC: B41J2/175
Filed: 1979-04-24
Abstract: PURPOSE:To remove corrosion and constitute the recording device in a simple construction by carrying out turning off or on of the ink pressure by means of an electromagnetic valve utilizing air in a device for carrying out recording by reciprocating and tracing a machine stand provided with impulse head type head blocks. CONSTITUTION:In a ink drop injection type recording device of an impulse pump system, an electrimagnetic valve 123 is opened during the recording operation but it is closed when the recording operation is stopped. By this procedure, although the air vent hole 111 of an accepting bedplate 113 for each of ink tanks 113 communicates with the atmosphere during the recording operation, it is interrupted from the atmosphere and closed when the recording operation is stopped. By closing the air vent hole 111, the ink pressure is turned off, and hence the leakage of ink from the orifice 55 due to the vibration of the recording device is prevented. In the recording device, it suffices to provide a single electromagnetic valve 123, and it is air which passes through the electromagnetic valve 123, and, therefore, there is no possibility of occurrence of corrosion.

Filed: 1986-03-06
Abstract: PURPOSE:To start the execution of a reasoning only by inputting a natural sentence and to proceed smoothly a question and answer cycle by providing a Japanese language interface and providing a deep layer structure extracting part in a reasoning module. CONSTITUTION:An input sentence inputted by a keyboard 1 is converted to a surface layer structure by the morpheme processing part and the syntax analyzing processing part of a Japanese interface 3. The surface layer structure is converted to the deep layer structure, which is the basic form of a reasoning calculation, by a deep layer structure extracting part 4a provided in a reasoning module 4. The deep layer structure is stored into a deep layer structure buffer. When the deep structure is fetched into a deep layer structure buffer, a reasoning mechanism interprets and executes what an operator expects at the time of the input continuously. Then, concerning the processing of a calculation formula included in an input sentence, some calculation mechanism is called out and processed from the reasoning mechanism. Thus, only by inputting a natural sentence, the execution of the reasoning is started and a question and answer cycle can be smoothly proceeded.

Abstract: PURPOSE:To obtain the titled paste having high bond strength free from loss of a soldering material even by soldering a lead fitment with a high-temperature soldering material, by blending Pd powder with low expanding frit with Ag powder and CuO. CONSTITUTION:Metallized paste consisting of 100pts.wt. Pd powder, 1-10pts.wt. low expanding frit, 0.5-4pts.wt. Ag powder and 0.1-pt.wt. CuO. Further the composition can be blended with <=50pts.wt. Au as a sintering auxiliary. Au has improving action on sintering properties of Au and wetting properties of pure Ag. The addition of >50pts.wt. Au is unfavorably expensive and causes loss of a soldering material. The low expanding frit is required to improve adhesiveness between the metallized paste and a ceramic substrate or a package.
