Filed: 1984-07-24
Abstract: PURPOSE:To aim at realizing a high pressure fuel injection and at facilitating the control of injection timing and fuel amount, by utilizing a low pressure type hydraulic pump providing with a distribution type or line type timer and a metering device, and a hydraulically driven injector provided with an amplifying piston in combination. CONSTITUTION:When a cam 102 driven by a cam shaft 101 which rotates in synchronism with the rotation of a crankshaft runs on a roller 103, a plunger 105 ascends to compress hydraulic oil in a cylinder 107. Then the hydraulic oil pushes up a discharge valve 108, and reaches a hydraulically driven injector 110 after passing through a conduit 109. Therefore, high pressure hydraulic coil depresses a plunger 11 provided with an amplifying device to compress fuel oil in an injector cylinder 112, which has passed through an oil feed pipe 119. As a result the fuel oil has a high pressure to push up a fuel injection valve 114, overcoming a valve spring 115, and therefore, fuel oil is injected from a jet port 116 into a combustion chamber 117 which is defined by a piston 118, etc.

Title: Developing device and image forming method using the same
Inventor: MIMURA KAZUYOSHI
IPC: G03G17/00
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To improve image quality by providing a developing roller with an elastic layer, made of a cured composition, whose surface is sticky, and a covering layer formed by attaching toner to the surface by means of the surface stickiness of the elastic layer. SOLUTION: In the developing roller 33, the conductive, elastic layer 41 composed of the cured, conductive composition is disposed around a conductive shaft 40 such as a metal shaft and, further, the covering layer 42 made of the toner or a material similar to the toner is disposed on the surface of the layer. This covering layer 42 is made of the toner or the material similar to the toner, which is attached by means of the surface stickiness of the conductive, elastic body 41. The surface stickiness of the conductive, elastic body 41 is a characteristic inherent to the material. Therefore, because the development toner which has built up is hardly charged frictionally, almost no change is caused in amount of charge.

Title: Electrophotographic developing device
Inventor: TAKASHIMA TAKEKAZU
IPC: G03G15/09
Filed: 1982-09-03
Abstract: PURPOSE:To obtain an excellent reversal picture having no fogging at the leading edge part of a sheet type recording medium, by lowing a bias voltage when a developing current which flows from a developing roll to the sheet type recording medium through toner exceeds a set value. CONSTITUTION:A bias power source 15 equipped with a bias voltage controlling means is connected to the developing roll 11, which is impressed invariably with a constant bias voltage which does not cause fogging in a stationary state. When the leading edge of the sheet type recording medium 3 is conveyed to near the developing roll 1 in said state, the developing current flows from the developing roll 11 to the sheet 3 through the toner. When a current greater than a maximum bias current flows, the bias voltage control means operates to lower the bias to obtain optimum development condition. As the toner starts banking up between the developing roll and sheet, the developing current decreases gradually and the bias voltage, therefore, increases to return to the stationary state gradually. Thus, the excellent reversal picture is formed over the entire surface of the sheet.

Title: Learning system for neural net
Inventor: JO KAZUKI
IPC: G06N3/08
Filed: 1989-06-15
Abstract: PURPOSE:To evenly recognize each data by learning more number of difficult-to- recognize data than the easy-to-recognize ones in a back propagation learning system. CONSTITUTION:An input layer 2 is prepared together with an intermediate layer 3 and an output layer 4 in a neural net where the learning is carried out by a back propagation learning rule. The recognizing result of each learning data and the value of a unit that ignited most with the output against the relevant learning date are checked before the change of the connection 1. Then the value obtained by multiplying the result and value together is defined as a degree of learning. Thus each learning data is correctly recognized and at the same time the degree of learning and the learning data obtained at that time point are wrong recognized. A function M is set in response to that degree of learning, and the weight of the connection 1 is changed based on the value obtained by a prescribed arithmetic formula. Thus the more number of difficult- to-recognized data are learnt and each data is evenly recognized. Then the convergence of learning is urged.

Title: High-frequency induction welding method of silicon material
Inventor: YAMADA GENZOU
IPC: B23K13/00
Filed: 1984-07-24
Abstract: PURPOSE:To produce easily a silicon frame having high purity and high quality by bringing a carbon heat medium body near to the position to be welded of silicon materials and heating said part to a high temp. then increasing high- frequency induction heating electric power to melt and weld said part. CONSTITUTION:High-frequency flows around a central square hole 3 when said current is passed from terminals 51, 52 to a coil 2. The high-frequency energy is first absorbed mostly by the heat medium body 7 to increase the temp. thereof. The temp. in the joint part of the silicon materials is also increased by the radiation heat from the body 7, by which the specific resistance of the silicon is decreased. Then the high-frequency induction current begins to flow toward the inside of the silicon. The distributing ratio of the absorbing electric power in the carbon medium body is decreased to attain an equil. state with a decrease in the specific resistance in the inside of silicon. The joint part attains the m.p. or above when the high-frequency electric power is gradually increased after the medium 7 is parted from the welding part. The joint part is welded by exerting slight pressure from an upper supporting bar and decreasing gradually the high- frequency electric power.

Title: Abnormality detecting device for air-fuel ratio sensor
Inventor: HINO HARUJI
IPC: F02D45/00
Filed: 1994-07-05
Abstract: PURPOSE:To prevent the inside and the outside of a detecting part from being decided to be normal even when the inside and the outside of the detecting part are temporarily brought into the same state as that when they are normal by a method wherein gas flowing through an exhaust passage is switched from only air to exhaust gas occasioned by combustion when the detecting part of an air-fuel ratio sensor is defected and the inside and the outside thereof are intercommunicated. CONSTITUTION:An oxygen sensor 29 is formed in a tubular shape and has a detecting part filled with air and based on a difference in density between the inside and the outside of the detecting part, an air-fuel ratio is detected. An electronic control unit (ECU) 35 measures a lean time in which an air-fuel ratio is rendered rich after it is rendered more lean than a theoretical air-fuel ratio, and decides that the oxygen sensor 29 is abnormal when the measurements exceeds a preset value. When during measurement of a lean time, gas flowing through an exhaust passage 8 is switched from air to exhaust gas occasioned by combustion, during a time in which a predetermined time starting from this point of time elapses, the ECU 35 forcibly continues measurement of a lean time even when an air-fuel ratio by the oxygen sensor 29 is switched from lean to rich.

Title: Step motor controller
Inventor: ARAI YOSHIHIRO
IPC: H02P8/28
Filed: 1991-06-26
Abstract: PURPOSE:To reduce power consumption of step motor by limiting power supply, current supply or voltage supply during pause interval with the intermittent driving timing of step motor. CONSTITUTION:When a voltage signal variable between a driving voltage Va(V) and 0(V) is applied during driving interval, a current Va/R(A) flows as the output current Iout for phase A. A voltage signal variable between a voltage Vb(V) lower than Va and 0(V) is applied during pause interval of coil LA and a current Vb/R(A) flows as the output current Iout for phase A. Similarly, output current Iout is suppressed by the voltage Vb(V) being applied during pause interval of other coils LA', LB, LB'. Consequently, current consumption of a step motor 21 is lowered during pause interval resulting in reduction of power consumption.
