Patent JP-H05223597-A (JP)
Title: Absolute encoder
Inventor: ONO YASUSHI
IPC: G01D5/244
Filed: 1991-03-04
Abstract: PURPOSE:To enable response to high speed by cutting off binary signals from an incremental pattern when the relative speed of a code plate and a detection plate is large. CONSTITUTION:A code plate A is laid out with a 1-track type absolute pattern C and an incremental pattern D of pitch lambda, and a detection plate B with pattern C sensors S1-S8 at interval lambda/2 and pattern D sensors S9, S10 at interval lambda/4. Two sinusoidal waves of the sensors S9, S10 are phase-divided by a dividing circuit E to generate eight rectangular waves of pitch lambda, lambda/2-lambda/2<7> and to convert rectangular waves, thereby detecting the relative speed of the code plate A and the detection plate B in a speed detecting circuit I. Even-numbered output is entered into a ROM circuit M when speed is a predetermined value or less out of the sensors S1-S8, even-numbered output when a predetermined value or more, and odd-numbered output when a predetermined value or more, where they are converted and outputted. A latch circuit F synthesizes absolute position signals with upper 4 digits and lower 8 digits of output of the dividing circuit E. When speed is a predetermined value or more, output of the dividing circuit E are all made into by a control circuit G.

Title: Reciprocating compressor
Inventor: HARADA SHINTAROU
IPC: F04B39/12
Filed: 1983-04-07
Abstract: PURPOSE:To elongate the life of a seal member and prevent the increase of compression work and the reduction of durability of a compressor by providing an after-cooler adjacent a cylinder for cooling working gas. CONSTITUTION:When a piston 2 moves from the upper dead point to the lower one, a discharge valve 7 is closed and a suction valve 6 is opened so that gas enters a compression space 21 from an intake port 15. When the piston 2 moves from the lower dead point to the upper one, the suction valve 6 is closed and the discharge valve 7 is opened by the increase of gas pressure in the compression space 21. While temperature of the gas pressure rises then, the gas is compressed in the compression space 21 and at the same time enters an after-cooler 5 or a thin pipe 16 to be cooled for preventing the rise of temperature. The piston 2 moves to the upper dead point while compressing the gas at this temperature, so that 1 cycle is completed.

IPC: H05K3/06
Filed: 1989-03-13
Abstract: PURPOSE:To prevent generation of a defect such as poor plating and poor etching by performing plasma treatment after putting in a state of being embossed from the surface of a printed wiring board. CONSTITUTION:After swelling a scum 5 of a part 4 deprived of a resist, plasma treatment is performed.

Title: Junction gate type field-effect transistor and manufacture thereof
Inventor: ONODERA TSUKASA
IPC: H01L21/337
Filed: 1986-03-19
Abstract: PURPOSE:To increase the processing precision of short gate element by a method wherein, after forming source/drain regions and a channel, a P-N junction of a gate is formed to remove the surface of a substrate excluding the gate part using a gate electrode as a mask. CONSTITUTION:After forming an N channel region 1 on an i-GaAs substrate 2, drain/source regions are implanted with Si ions to form an N<+> drain 7 and a source 11 in high concentration. Next, a part of region 1 is implanted with Z ions to form a P<+> region. Furthermore, a gate electrode 3 smaller than the P<+> region is formed on the P<+> region.

Title: Formation of resist pattern
Inventor: OSHIO SHUZO
IPC: G03F7/20
Filed: 1986-03-19
Abstract: PURPOSE:To form an inverted trapezoidal resist pattern using a single type resist only without substantial increase in the number of manufacturing processes by a method wherein a different sensitivity is given to the upper and the lower layers of the resist by providing a temperature gradient in the direction of film thickness, and an exposing process is performed selectively. CONSTITUTION:A negative type photoresist film 2 is coated on the upper surface of a substrate 1 in the thickness of 1.0-1.5mum, and irradiation of ultraviolet rays is made through the light-transmitting part of the mask 4 set above the substrate 1. The temperature of the upper surface side of the resist film is raised by the radiation of heat coming from a mercury lamp, but on the contrary, the temperature of the substrate side drops by the radiation of heat to a stage, and a temperature difference of 5 deg.C or thereabout is given in the direction of thickness of the resist film. When an exposing process is performed in the above-mentioned state, the melting speed in the development process is decreased by the acceleration of crosslinking on the upper part of the resist film, whereas, the progress of the crosslinking on the lower part of the resist film is slow due to a low temperature, and the resist film is fused quickly at the time of development. As a result, the lower layer of the resist film is removed by melting more than the upper layer, and the resist pattern is formed into an inverted trapezoidal shape.

Abstract: PURPOSE:To eliminate frequency adjustment of a low frequency oscillation circuit by obtaining a reference time signal corrected with a high frequency oscillation circuit with the contents of a phase difference counter automatically converging to zero. CONSTITUTION:An oscillation block 71 inputs an correction value CC to output a low frequency signal fL corrected with respect to a reference low frequency oscillation frequency fB and a division block 73 outputs a reference time signal fW and a sampling signal fS.

A phase difference count block 74 receives the phase difference signal fP, a reference time TP and a high frequency deviation correction value Ch as input and outputs phase difference count CP. A correction value renewing block 75 receives the phase difference count CP as input and updates and outputs a correction value CC. Thus, with an intermittent updating of the correction value CC, the deviation block 72 provides the reference time signal fW constantly corrected with the correction value CC.

Filed: 1982-04-13
Abstract: PURPOSE:To obtain a high speed transistor by forming an emitter, base, collector forming P-N junctions, and a gate through the P-N junction, Schottky barrier or an insulating film opposite to the base at the collector and depleting the base and the collector at the operating time. CONSTITUTION:When a positive low voltage Ve is applied to an N type emitter 1, a positive high voltage Vc is to an N type collector 3 and a negative voltage Vg is to a gate 4 with a P type base 2 as a reference, P-N junctions are all reversely biased, and the base 2 and the collector 3 are completely depleted except the P<+> type terminal layer 21 and N<+> type terminal layer 31. At this time minority of information carrier which passes through the base 2 is accelerated by the electric field of the collector 3, the collector 3, and the operation of the transistor is accelerated. Further, since the input impedance from the gate 4 is high in its capacity and the base and collector are depleted, capacities CEB, CEC, CBE are all extremely small, and high speed operation is further enabled.

The trainee, then, floats the hands and moves the hands in parallel on the keyboard while retaining the shape of the ten fingers as it is. If the trainee places the little finger of the left hand on the key A, the little finger of the right hand exists on the key.  Not only the 'A', but all the vowel keys 'I, U, E, O' exist in the home positions and, therefore, the greater part of Japanese sentences may be keyed without the movement of the fingers.
