Patent JP-H03223891-A (JP)
Title: Signal level display circuit
Inventor: TAKAHASHI KIYOSHI
IPC: H04N5/445
Filed: 1990-01-30
Abstract: PURPOSE:To adjust the level of a signal without using a measuring device by executing 1st comparison between a saw tooth signal and a level detection signal and 2nd comparison between the saw tooth signal and a reference voltage, thereby executing the 1st comparison in a 1st signal period and the 2nd comparison in a 2nd signal period. CONSTITUTION:A signal (e) from the connection point of the switches SW1 and SW2 and a vertical saw tooth voltage Vs are respectively conducted to the non-inversion input terminal and the inversion input terminal of an operational amplifier A4, which outputs a signal (d) that changes to a high level and a low level and is obtained by comparing the signal (e) and the voltage Vs and supplies it to a picture tube CRT. Therefore, in the case that the level detection signal Vi is equal to the reference voltage VR by setting the level of the reference voltage VR equal to the central potential of the saw tooth signal, an image which is equally divided up and down on a screen is obtained. When the reference voltage VR and the level detection signal Vi are different, the image which has the different ratio of an upper part to a lower part on the screen is obtained in the first half of a horizontal cycle. Thus, the level of the image signal is adjusted with a sense of viewing a level meter displayed on the screen without using the measuring device.

Title: Electronic type watthour meter
Inventor: TAKAHASHI KATSUHIKO
IPC: G01R21/133
Filed: 1991-01-23
Abstract: PURPOSE:To correct the error and offset of the gain of a voltage and current converter at the time of the full load of an object to be measured by correcting the reference voltage of an A/D converter whose conversion ratio is prescribed by reference voltage to the optimum value. CONSTITUTION:Voltage whose value corresponds to full load and is converted to voltage Vmax0 when a voltage converter 2 is accurately prepared is applied to the voltage input terminal 1 of the voltage converter 2. The voltage Vmax1 after conversion is converted to a digital value by an A/D converter 6 through a multiplexer 5. A CPU 7 issues a command to the bias circuit 11 in a correction means 20 while monitoring the digital value. The circuit 11 outputs the signal corresponding to the command to a reference voltage circuit 8 and, for example, in the case of Vmax1 >(<)Vmax0, the reference voltage Vr of the A/D converter 6 is increased (decreased) not only to increase (decrease) voltage per one bit but also to reduce (increase) the digital value so as to bring the same to the value corresponding to Vmax0. By this method, the error and offset of the gain of the converter are corrected.

Title: Rotor of flywheel magnet equipped with trigger pole
Inventor: KAMIDATE MAKOTO
IPC: F02P1/02
Filed: 1984-02-07
Abstract: PURPOSE:To obtain a large moment of inertia, increase the strength of a crankshaft installation hole, facilitate machining and cut cost, by soft nitriding treating trigger poles which are welding-fixed onto the rim part of a rotor and the rotor body. CONSTITUTION:The thickness of a rim part 21c is made to be sufficient to provide a necessary moment of inertia for a rotor 20c, and two trigger poles 22a and 22b which are formed by cutting a cold-pressed steel plate having a prescribed thickness into paper-strip form and bending said steel plate along the outer peripheral surface are welding-fixed onto the outer peripheral surface of the rim part 21c. After the trigger poles 22a and 22b are welded onto the rotor body 21, these members 21, 22a, and 22b are soft-nitriding-treated, and all the surface including the inner surface of a tapered hole 21d is hardened. Therefore, the moment of inertia of the rotor 20 can be increased, and since the material is low-carbon steel, turning work is facilitated, and trigger poles can be easily welded onto the outer peripheral surface of the rim. Further, since the soft nitriding treatment generates little stress, correcting machining is hardly necessitated, and production cost can be cut. Further, the strength of the installation hole onto a crankshaft can be increased.

Title: Optical information recorder and driving method for semiconductor laser used for this recorder
Inventor: YAMAGUCHI EIJI
IPC: G11B11/10
Filed: 1992-01-13
Abstract: PURPOSE:To enable direct verification with high stability by using a semiconductor laser having an active layer consisting of two light emitting layers and imaging spots for recording and reproducing apart prescribed intervals in tracks. CONSTITUTION:A semiconductor laser driving circuit 22 supplies driving currents in correspondence to recording signals to the semiconductor laser 6. The laser 6 had the active layer consisting of the two light emitting layers and outputs light rays of wavelengths lambda1, lambda2. These light rays are no longer paralleled in optical axes with each other by the wavelength dispersion characteristic of a beam shaping prism 4 and are projected as light spots 104, 103 of the wavelengths lambda1, lambda2 onto a recording surface. The light spot 103 is the light output of a high light intensity and, therefore, a recording pit 102 is recorded on the recording surface. This pit is scanned thereupon by the light spot 104. The light spot 104 is set at a reproducing power and, therefore, information is not recorded. The light spot 104 is detected by photodetectors 13, 15 and is then reproduced. The information of the recording pit recorded by the preceding light spot 103 is reproduced.

Title: Steering shaft device
Inventor: WATANABE JIYUNYA
IPC: B62D1/19
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To prevent a steering shaft from being pushed up in car crush. SOLUTION: A pin yoke 1 and a socket yoke 2 are mounted on the arm section extending toward the outside in the axial direction and both directions of a coupling yoke 3 through cross pins 4 and 5. This steering shaft device is constituted in such a way that when a steering shaft is positioned at the neutral position, the axis line of the shaft supported by the coupling yoke 3 of the cross pins 4 and 5 extends in the cross direction of a vehicle. Since when force works in the direction to enlarge a joint angle because wheels are pushed backward due to the shock in car crash, the socket section 2a at the tip of the socket yoke 2 readily comes off from the inside of the coupling yoke 3, enlarging the joint angle, impact force is not transmitted to the steering shaft side, preventing the steering shaft from being pushed up.

Title: Atomizing feed nozzle and its use method
Inventor: MULDOWNEY GREGORY PATRICK
IPC: C10G11/18
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To atomize a liquid stream in the presence of a dispersion medium for making fine liquid droplets by tapering the inner surface of a first conduit located in a mixing zone which reduces the cross section area of the first conduit in the mixing zone. SOLUTION: The tapered inner surface 30 of a first conduit 20 across the length 35 of mixing zone 26 forms a thin liquid film 39 by gradually reducing the thickness 37 of a liquid stream. The degree of a taper is shown by an angle θ(52) formed between the inner surface 21 of the first conduit and the tapered inner surface 30. When the liquid film 39 continues to move along the inner surface 30 tapered conically, ripples are formed along an interface 36 of the dispersion medium and the liquid, and a thick band 38 and a thin band 40 of the liquid film 39 are alternately formed.

Title: Feedforward controller for inverse response process
Inventor: KUWATA RIYUUICHI
IPC: G05B17/00
Filed: 1979-02-27
Abstract: PURPOSE: To enable perfect control so that the control variable can not be disturbed due to external disturbance, by transmitting amount of operation through the reduction of the output signal of transfer characteristic element from the output signal of the element receiving external disturbance signal.  
     CONSTITUTION: In the process control having the characteristics of tentative inverse response, the signal reception element RE receives external disturbance and provides the element G(S) of transfer characteristics determined with the characteristics of control objective process. Further, the output signal of the reception element RE for external signal is inputted to the transfer element G(S) to subtract the output signal M 2  of transfer characteristic element from the output signal M 1  of the reception element RE for external disturbance signal and to activate the amount of operation. Thus, the process control having the characteristics of tentative inverse response enables perfect control so that the control amount can not be disturbed with external disturbance.
