Abstract: PURPOSE: To keep the stable operation of a feedback control system for compensating the inequality of an O 2  sensor by compensating the time width of the output signal of the O 2  sensor indicating an air-fuel ratio over or under a fixed level directly.  
     CONSTITUTION: A comparison circuit 10 is used to compare the output signal of the first O 2  sensor 8 provided in the upper stream of a ternary catalyzer 7 with a fixed level, and outputs a signal to indicate the air-fuel ratio to be over (lean) or under (rich) the fixed level. The output signal from this comparison circuit 10 is delayed by a delay circuit 20, and given to an electronic control unit 6 through an integration circuit 40. The delaying time in the delay circuit 20 is regulated by a delaying time regulating circuit 30 according to the output signal of an O 2  sensor 9 provided on the downstream side of the ternary catalyzer 7.

Abstract: PURPOSE:To execute a fine surface treatment effectively by a method wherein a semiconductor is etched by using silicon dioxide and/or aluminum oxide or a double structure of the two and a photoresist as a mask and by using a plasma of dichlorodifluoromethane gas. CONSTITUTION:When specimens 30, 32 on which a mask of a laminated structure of a first mask layer 4 and a second mask layer 5, of prescribed shapes, has been formed on GaN are plasma-etched, the specimens 30, 32 are placed on an electrode 24 and a residual gas inside a reaction chamber 20 is then evacuated sufficiently by using a diffusion pump 19. After that, CCl2F2 gas is introduced into the reaction chamber 20 while a flow rate is being controlled by using a mass-flow controller 14. When high-frequency electric power is supplied between electrodes 24, 22, the introduced CCl2F2 gas is set to a plasma state by a glow discharge, and an etching operation of the specimens 30, 32 is started. By this etching operation, a photoresist of the second mask layer 5 is etched, and the first mask layer 4 is left. SiO2 of this mask layer 4 is etched and removed. After this assembly has been cleaned, it is dried. A fine processed surface whose shape is slackened little can be obtained.

Title: Joy stick device
Inventor: TEI TOSHIAKI
IPC: G05G9/047
Filed: 1994-04-27
Abstract: PURPOSE:To securely prevent an operation lever from being locked with the braking force of an electromagnetic brake and improve the safety by providing a lever lock restricting means which restricts the locking of the operation lever based upon the braking force of the electromagnetic brake. CONSTITUTION:Although the input voltage V to the electromagnetic brake 24 rises in proportion to the output (u) of a load detection sensor and the output UJ of a potentiometer 22, a correction function g(theta) and a constant (k) control the return torque of a neutral return spring arrester 15 within a neutral return torque range since the input voltage V is so corrected that the braking torque of the electromagnetic brake 24 does not exceed the neutral return torque. Consequently, the lever locking caused when the braking torque exceeds the neutral return torque can securely be restricted. This constitution can securely evade such trouble that the operation lever 11 is locked on the basis of the braking force of the electromagnetic brake 24. Further, the safety of a load sense type joy stick device can greatly be improved.

Filed: 1977-09-19
Abstract: PURPOSE: To improve the accuracy of a tape running time display counter by letting n-scale and sexagesimal reversible counters be operated by the detection signals of two phases corresponding to tape movement quantities.  
     CONSTITUTION: Detection singnals differing in phase by 90° are generated at the frequencies corresponding to the movement quantities of tape 1 by the light emitting elements and photo detectors 29 and 30, 32 and 33 which are installed on the radii of an encoder 28 mutually at an angle of 90° by way of the rotary encoder 28 turning cooperatively with a revolving post 27 which revolves in correspondence to the running directions and running quantities of the tape 1. These 2-phase signals invert the polarities of the latch outputs of D type FF 142 according to the tape running directions, to cause a reversible n-scale counter 144 to up-or down count the pulses such as of an amplifier 39, etc., whereby the highly accurate tape movement quantity being 1/n the peripheral length of the post 27 is determined. Hence, if the count value of this counter 144 is subjected to time processing with a sexagesimal reversilbe counter, the tape running time is displayed in the hour, minute and second with high accuracy

Title: Sheet separating mechanism for sheet feeder
Inventor: FUJIOKA SATOSHI
IPC: B41J13/00
Filed: 1988-05-09
Abstract: PURPOSE:To provide separability in quick response to the sort of sheet by furnishing a separating pawl capable of advancing and retracting inside a sheet guide, detaining normal sheets with this pawl at the bottom corner, and retracting the pawl for thicker sheets. CONSTITUTION:In the case of thin sheets, they H1 slide on a slope 12 and can not move a separating pawl 20, and only one at the top will buckle and get over the pawl 20 to be forwarded to the printer body. In the case of stiff sheets, accommodation is made upon adjusting the position of a hopper so as to be in agreement with the cross width of the sheets H2, and when the printer is turned on, the sheet is pulled out downward by sheet feed rollers 5, 5. Therein the stiffness of the sheet H2 overwhelms the resilient force of the separating pawl to cause generation of a force to rotate the pawl 20 ahead, and a gap to allow passage of one sheet is formed between the pawl 20 and slope 12, so that each sheet H2 which has slided on the slope 12 passes through this gap to proceed downward. Thus the sheet H2 will be set in the printer without being buckled by the pawl 20.
