Title: Ink jet recording apparatus
Inventor: MATSUMOTO SHUZO
IPC: B41J2/05
Filed: 1988-12-26
Abstract: PURPOSE:To enhance energy efficiency by selectively irradiating the recording liquid in a liquid chamber with electromagnetic wave energy to heat the recording liquid and reflecting the electromagnetic wave energy transmitted through the recording liquid by an electromagnetic wave reflecting layer to reutilize the transmitted energy in the heating of the recording liquid to emit a liquid droplet. CONSTITUTION:The laser beam transmitted through the first substrate 5 to be incident to a recording liquid 2 is absorbed by said liquid but a part of said laser beam transmits through the recording liquid 2 to be discharged to the outside of said recording liquid 2. When an electromagnetic wave reflecting layer 3 low in the absorbancy and transmissivity of laser beam and having high reflectivity against said beam is arranged to the wall surface of a liquid chamber, the laser beam transmitted through the recording liquid 2 is reflected by said layer 2 to again advance through the recording liquid 2 and absorbed by said liquid 2. At this time, when a focal position is controlled to the vicinity of the layer 3, the reflected laser beam is almost reflected to a focal region to concentrate energy effectively. Therefore, when a laser beam driving pulse is turned ON, a sudden heating state is formed at a focus and an air bubble is generated and expanded in the liquid 2 and, by the pressure change due to said air bubble, the recording liquid 2 is emitted from a jet orifice 1.

Title: Production of optical fiber
Inventor: SETO KATSUYUKI
IPC: C03B37/027
Filed: 1992-11-16
Abstract: PURPOSE:To provide a process for producing an optical fiber at a high drawing speed by increasing the cooling efficiency of fiber immediately after the drawing process. CONSTITUTION:A quartz-based optical fiber preform is drawn in the form of a fiber. Immediately after the drawing of the preform, the formed fiber is cooled with hydrogen gas and then coated with a UV resin, etc. Since hydrogen gas has a conduction efficiency of as high as 0.1682W/m.K and excellent cooling efficiency, even a hot fiber drawn at a high speed (about 1200m/min) can be quickly cooled. Accordingly, the high-speed drawing of an optical fiber can be carried out without causing the generation of bubbles and the deterioration of the appearance caused by the temperature increase of the coating resin.

IPC: H01L21/22
Filed: 1993-12-01
Abstract: PURPOSE:To prevent contamination, which is generated at a region where heating units exist, from infiltrating into a heat-treating region where matters to be treated exist. CONSTITUTION:A soaking tube 31 is made to interpose between a reaction tube 41 to be loaded with wafers W, which are matters to be treated, and heating units 6 for creating a heat-treating atmosphere.

IPC: F04B39/00
Filed: 1989-12-20
Abstract: PURPOSE:To suppress drop of the dielectric resistance simply by applying plastic coating to the surface of a receptacle terminal and the inner side face of an airtight terminal forming electrode while fitted to each other, and thereby decreasing the area of electrode exposed to the refrigerant. CONSTITUTION:In a motor-driven compressor 1, a motor part 4 and a compressor part 3 driven thereby are accommodated in the upper and lower parts of a sealed vessel 2, in which lubricant is stored at the bottom. A receptacle terminal 16 fixed to the end of a lead 15 at this motor part 4 is fitted on a pin 22 on an airtight terminal 17 secured to the lower part of the sealed vessel 2, and thus an electrode is formed. In this constitution, the sealed vessel 2 inner side face of the airtight terminal 17, the peripheral surfaces of the pin 22, and the whole surfaces of the receptacle terminal 16 are coated with a covering layer 23 of synthetic resin having resistance against refrigerant and oil, for ex. ethylene tetrafluoride resin.

Title: Diagnostic processor
Inventor: HISHINUMA TAKAYUKI
IPC: G06F11/34
Filed: 1988-12-26
Abstract: PURPOSE:To prevent the occurrence of exchanging mistakes by disposing a display device approximating and corresponding to a fault exchange unit and displaying the fault area pointed by a diagnostic process part in approximation to a fault part and recording the exchanging result. CONSTITUTION:Plural display devices 3 are disposed in approximation to the fault exchange units 11 - 1N connected to a diagnostic process part 1 respectively. When a fault occurs at a part 10 to be diagnosed, the part 1 collects the fault data from the part 10 and analyzes these data to decide the area of the fault. When the fault area is decided, the device 3 corresponding to the fault exchange unit including the fault area is turned on to report the fault. Thus a maintenance engineer exchange the fault exchange unit corresponding to the lighting device 3 with the nondefective one. Then an exchange switch 4 is opened/closed, and the part 1 turns off the lighting device 3 when the correct exchange of the exchange units is confirmed and at the same time records the exchanging result data to a data recording part. Thus it is possible to eliminate the exchanging mistake and the misexchange.

Title: Heat body detector
Inventor: MASUO YOSHIHISA
IPC: G01J1/42
Filed: 1987-12-26
Abstract: PURPOSE:To highly accurately detect a heat body even if a background temperature is changed by providing the title device with an infrared detecting means, a threshold level signal generating means and a comparing means. CONSTITUTION:The infrared detecting means 11 including a detecting element 1a generates an electric signal corresponding to infrared ray energy in a prescribed area. The threshold level signal generating means 12 forms a threshold level signal corresponding to the quantity of infrared ray energy radiated from the prescribed area. The comparing means 13 compares both level signals outputted from the means 11, 12 with each other and decides the existence of a heat body. Since the heat body is detected by comparing the signal outputted from the detecting means 11 with the threshold level signal, the influence of a changed in a background temperature due to the influence of sunbeams or the like or variation in a detecting signal level due to the fine movement of a static human's hand, foot, etc., in a monitoring area can be suppressed at its minimum.
