Patent JP-H04101436-A (JP)
Title: Field-effect transistor
Inventor: MATSUZAKI KENICHIRO
IPC: H01L21/205
Filed: 1990-08-21
Abstract: PURPOSE:To improve the characteristics of FET interposing a first conductivity type semiconductor layer with its impurity concentration higher than the buffer layer between the buffer layer and a channel layer. CONSTITUTION:This invention comprises pulse dope structure formed on a semi-insulation GaAs substrate 1, a source electrode S, a drain electrode D, and a gate electrode G formed on the surface. An impurity implantation region into which N<+> ions are implanted in a self-alignment/manner, is formed below the source electrode S and the drain electrode D. This pulse structure P uses an undoped p<-> type GaAs layer 2, which is a buffer layer, an n<+> type GaAs layer 3, which is a channel layer, and an n<-> GaAs layer 4 whose impurity concentration is lower than the layer 3 and serves as a cap layer. A p<+> type GaAs layer 5, whose impurity concentration is higher than the GaAs layer 2, is arranged to be present between the layer 2 and the layer 3, which makes it possible to enhance the effect to confine the carriers under the pulse dope structure and improve the FET characteristics for mutual conductance or the like.

Title: Connector
Inventor: TABATA MASAAKI
IPC: H01R13/42
Filed: 1996-08-21
Abstract: PROBLEM TO BE SOLVED: To sense certainly a half inserted condition of a terminal. SOLUTION: A sensing projection 34 to interfere with a stabilizer when a female terminal 20 is in a half-inserted state, is positioned in front more than the center of a retainer 30. Accordingly, the front part of the retainer 30 will protrude to the fitting area of the hood part 41 of the mating connector housing 40 from the bottom surface 15 of the connector housing when the female terminal remains in half insertion, so that the foremost part of the hood 41 collides with the front of the retainer 30 when the hood 41 is going to be fitted, which should restrict the fitting of the hood 41 certainly to lead to enhancement of the reliance upon sensing of the half inserted condition of the female terminal 20.

Title: Construction machine
Inventor: TADOKORO WATARU
IPC: E02F9/24
Filed: 1999-08-03
Abstract: PROBLEM TO BE SOLVED: To simplify the connection part constitution of a rise and fall lever and lock valve. SOLUTION: A mounting block 45C is rigidly fixed to the base end side of a rise and fall lever 45, and the mounting block 45C is fitted to a rotating shaft 44 of a lock valve 41 provided on the lower face side of a floor plate 5A.

Title: Dc power unit
Inventor: KAMATA HISAHIRO
IPC: G05F1/613
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To suppress the weight, size, and cost of a DC power unit and, at the same time, to improve the power factor of the power unit. SOLUTION: AC power inputted from an AC power source 1 flows to a negative common line from a positive hot line through a choke CH, capacitor C1, and transistor Q1 after the power is full-wave rectified by means of a diode bridge 2 and charges a capacitor C1. The current discharged from the capacitor C1 is supplied to a load 3 through a diode D1, the capacitor C1 and the choke CH. A switching control circuit(SWCC) 5 detects the voltage of the hot line and, while the instantaneous value of the detected voltage is higher than the DC-component voltage of the detected voltage, namely, during the charging cycle of the capacitor C1, outputs a driving signal which switches the transistor Q at a high speed.  Therefore, the peak current of the AC power source 1 is remarkably reduced and the power factor of a DC power source is improved, because the control circuit 5 works as a choke input smoothing circuit even when the inductance of the choke CH is small, reduces ripples, and widens the conducting angle.

Abstract: PROBLEM TO BE SOLVED: To reduce energy consumption by filter regeneration means. SOLUTION: An exhaust passage 10 of a diesel engine is branched into a first exhaust passage 14 and a second exhaust passage 16 in which a filter 22 to collect particulate matters is interposed. An opening control valve 20 is provided at a branch portion 12 and a bypass passage 28 is provided for communicating upstream and downstream of the filter 22. An electric heater 24 as filter regeneration means is provided upstream of the filter 22, while a blower 32 is interposed in the bypass passage 28.

IPC: H05K13/04
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To obtain an aligning method for an automatic assembling system in which the parts can be assembled while being aligned highly accurately with no limit to dimensions thereof. SOLUTION: The attitudes of a body 10 to be assembled and an assembling parts 11 are detected by measuring the position of more than one measuring part for each of them. The shift of body 10 to be assembled from the assembling position of assembling parts 11 is then determined based on the decision results of the attitude. Since the assembling parts 11 is aligned by means of an X-Y-X-θ robot while taking account of the shift thus determined, it can be assembled at an accurate assembling position into the body 10 to be assembled while judging the relative positional relationship between the body 10 and the parts 11 highly accurately regardless of the dimensions of the assembling parts 11.
