Title: Fuel injection nozzle
Inventor: IIYAMA AKIHIRO
IPC: F02M61/16
Filed: 1989-11-27
Abstract: PURPOSE:To prevent dispersion in the atomization state in each injection hole as well as the generation of the defect of a sheet by setting a contact between a needle valve and a spring bearing on the center shaft of the needle valve, and on the inside of a sliding part. CONSTITUTION:A contact S of a needle valve 11 and a spring bearing 12 is set on the center shaft of the needle valve 11, and on the inside of a sliding part 11a. The spring bearing 12 is tilted due to the curving of a spring 6, difference in accuracy and so on of a lift regulating plate 3, of a nozzle holder 4, and of spring bearings 8, 12, whereby the needle valve is not energized in an upright condition. When it is energized in an oblique direction, the contact S of the needle valve 11 and the spring bearing 12 is located on the center part of the inside of a sliding part 11a of the needle valve 11, whereby rotational force that rotates the needle valve 11 obliquely is not generated. When the energizing power works on the needle valve 11 obliquely, the entire one side of the sliding part 11a is pressed in the direction of the component force generated in a perpendicular direction of shaft, whereby the eccentricity of the needle valve 11 includes only a clearance C between the sliding part 11a, to a nozzle chip 1, and decreases in this way.

Title: Method and device for ground excavation with pressure air injection and vacuum suction
Inventor: YAMAGATA HAJIME
IPC: E02F3/34
Filed: 1991-11-20
Abstract: PURPOSE:To perform excavation safely and easily by spouting compressed air from a nozzle for preceding penetration, scratching, tearing, and crushing a natural ground with a bunch of cutting pawls installed projectingly on a rotary drum, and sucking and removing the produced material through a suction pipe. CONSTITUTION:Compressed air is spouted from a nozzle 6' to a natural ground in the place to be excavated, for preceding penetration, and the natural ground is scratched, torn, and crushed with a bunch of cutting pawls 7 installed projecting on the peripheral surface of a subsequent rotary drum 9 in rotating. Then the material wound up by means of rotational induction of the rotary drum 9 is sucked and exhausted from a suction hole of a suction pipe 11 which opens at an anchor plate 10 along with proceeding of the excavation. In this place excavated, such things are embedded as pipeline for communication, service water pipe, sewer pipe, gas pipe. etc. This permits performing excavating works without damaging underground embedded objects or without requiring particular skillfulness.
Patent JP-H04177907-A (JP)
Title: Input circuit
Inventor: MORITA TOMONORI
IPC: H03F3/45
Filed: 1990-11-09
Abstract: PURPOSE:To attain the normal operation even when a DC bias at an input terminal is fluctuated by connecting an output of a 1st switching FET in a couple of switching FETs to a gate of a 2nd switching FET via a capacitor. CONSTITUTION:A capacitor C1 is arranged between a drain electrode of a switching FET 101, that is, an output 119 and a gate electrode of a FET 102. The capacitor C1 delivers a potential change in the drain electrode 119 to a gate electrode of the FET 102. Since a potential change at a node 119 is opposite phase to a potential change fed to a gate of the FET 101, the FETs 101, 102 are operated at an opposite phase, that is, the FETs act like biphase drive type FETs. Thus, even when a DC level at the input terminal is fluctuated due to any cause, the two output DC levels opposite to each other in the differential amplifier circuit are prevented from being parted, the overlapped waveform is kept large and the operation of the differential amplifier circuit is kept normal.

Title: Line switching system by fault at sending end
Inventor: NAKAJIMA TOSHIO
IPC: H04B1/74
Filed: 1988-12-02
Abstract: PURPOSE:To reduce a standby monopoly rate due to a fault of an active line by detecting a fault while distinguishing a fault of a carrier interface section at the sending end from a fault of an interface section of a bipolar unipolar converter and of a sending end switch. CONSTITUTION:In the case of a fault at a point A being a carrier end interface section and in the occurrence of production of AIS, an FF is latched and alarm information is outputted at its Q output. The switching operation of a sending end switch TSW is started by alarm information. In the case of a fault on the point A, a standby line is brought into the AIS state and its information is applied as a reset signal of the FF. Thus, after the occurrence of AIS in the standby line, the status information of the AIS in the active line is inhibited and chattering of the changeover of the sending end switch TSW is prevented. If a fault takes place at an interface section (point B) between the sending end switch TSW and a bipolar unipolar converter B-U, since no AIS is detected because the level of the standby line is at 11, a receiving end switch RSW is changed over. Thus, a signal (data) is sent by using the standby line.

IPC: G06F3/033
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to use an operating means for inputting information to a computer irrespective of the sequence of starting of the device in a picture display device. SOLUTION: Sources PCV and GND are supplied to a mouse connector 228 via a connecting cable 12 from a PC 10. These sources PCV, GND are defined as sources to operate each block forming a mouse function part 220, i.e., an IR light receiving part 222, selector 224 and mouse I/F controller 226. Thus, source is supplied to each configuration part of the mouse function part 220 at the almost same time as the starting of the PC 10, and they are to be operable. At this time, the PC 10 checks a prescribed signal which is included in a mouse data signal MSDATA and confirms whether or not to be in a mouse operable state. Thus, the mouse function is used as well as the PC 10 is started irrespective of that the picture display device is operated or not.

IPC: H01F41/02
Filed: 1986-12-22
Abstract: PURPOSE:To prevent deterioration in magnetic characteristic and form a resin film by forming a magnetic core of an amorphous magnetic material having magnetic distortion, and polymerizing the resin gasified and decomposed at a high temperature at the surface under normal temperature for solid-dification. CONSTITUTION:A wound magnetic core is formed of an amorphous magnetic material having positive magnetic distortion and it is then annealed. Next, after a raw material A of paraxylene as the casting resin is vaporized to gas within a vaporization furnace, it is phrolyzed within a decomposition furnace 2. This monomer gas is absorbed with a vacuum pump within a vaporization furnace 3. A magnetic core 7 after annealing is housed in a rotating chamber 5 of a vaporization furnace 3 and the rotating chamber 5 is rotated. Thereby, the surface of magnetic core 7 is equally exposed to the gas to effect polymerization at the surface of magnetic core 7 under the normal temperature and then a polyparaxylene film can be formed. Thereby, a resin film can be formed by preventing deterioration of magnetic characteristics.

Abstract: PURPOSE:To shorten the heating up time, to decrease a heater capacity for heating and to uniformalize the temp. distribution over the entire width of a roller by constituting the end of the roller of a thermoplastic resin having the thermal deformation temp. of a specific value or above. CONSTITUTION:The shaft end 1b of the heat fixing roller 1 is constituted of a heat resistant polyimide resin having >=200 deg.C thermal deformation temp. The thermal deformation temp. is preferably >=230 deg.C. Such thermoplastic resin is exemplified by a polyimide resin, polyamide imide resin, polyether ketone resin, arom. polyester resin, polyphenylene sulfide resin and polybenzimidasole resin. This heat fixing roller shuts off the escape of the heat of the metallic roller heated by a heater for heating through shaft flanges then through bearings and gears. As a result, the heater capacity is decreased and the uniformity of the temp. distribution of the roller surface is greatly improved as compared with the conventional heat fixing rollers. The toner fixing with the good quality is thus executed.
