Title: Controller for alternator in vehicle
Inventor: WATANABE HIRONORI
IPC: H02J7/14
Filed: 1995-06-05
Abstract: PURPOSE: To prolong the service of lamps in a vehicle by sustaining the charging efficiency of battery in good state. CONSTITUTION: When a switch 7 is turned on, output from a Tr 402 goes Low and a Tr 305 becomes nonconductive. When the duty ratio for turning the field current on/off detected by a detector 8 is lower than a predetermined level in this state, a voltage division point B is not yet grounded and the output voltage from an alternator 1 is regulated to a first level (13.5V). When the detected duty ratio is higher than the predetermined level, the voltage division point B is grounded and the output voltage from the generator 1 is regulated to a second level (14.5V). When switch 7 is turned on, output voltage from the alternator 1 and the terminal voltage of a battery 5 lower as the voltage at a voltage division point A lowers regardless of the detected duty ratio.  Consequently, the voltage at the voltage division point A lowers to cause increase of the output voltage from the alternator 1 and the terminal voltage of the battery 5. The operation is repeated and the output voltage from the alternator 1 is regulated to the second level.

Title: Dot type printer
Inventor: KOUNO MITSUNORI
IPC: B41J2/295
Filed: 1978-11-07
Abstract: PURPOSE:To enable reduction in the size while minimizing noize and vibration with less drive energy per one impact by means of a drive element for giving self-resonant vibration being mounted on the arm member supporting the hammer section. CONSTITUTION:While a pressure-sensitive paper is fed at a constant speed with a feed roller 1, a pulse-like AC signal is applied by an envelop across terminal 101 and 102. Consequently, for example, when a piezoelectric element is used for the drive element 10, the element varies in the thickness facing between the electrodes to give vibration to arm members 9. If one of the members resonate to the frequency of the AC signal applied, the arm begins to vibrate at the amplitude several to several scores times as large as that of the drive element 10 whereby the hammer at the tip gives a strong impact on the paper to effect a printing. The respective arm members are made in varied resonant frequencies so that the drive signals are allowed to be selectively applied according to the desired arm members.

Abstract: PURPOSE: To avoid occurrence of the phase distortion and then to solve the buzz of the aural signal by supplying the tuner's output to the BPF featuring such characteristics in that the range where the double side-band wave centering on the video carrier frequency exists is flat.  
     CONSTITUTION: The color TV signal received through antenna 1 is supplied to mixer 3 via high-frequency amplifier 2 and then supplied to the video intermedium frequency amplifier via BPF5 after the frequency conversion. The signal sent from  amplifier 6 is supplied to multiplier 7 as well as limiter 9 via BPF8, and the  carrier of this output is supplied to multiplier 7. The output of 7 is supplied to correction filter 10. BPF5 features such characteristics in that the range where the double side-band wave centering on the video carrier frequency exists is flat, and as a result the amplitude distortion and the phase distortion can be eliminated. However, this output features the amplitude of the low-range band whose level is double as high as other band component. Thus the detection output is corrected by filter 10 featuring the frequency characteristics in that the amplitude of the low-range component is 1/2 the other band amplitude.

Abstract: PURPOSE:To provide a main spindle temperature control method and device which control cooling of main spindle head circulating cooling liquid so that the temperature of a main spindle is adjusted to a given value in a short time during the starting of the main spindle of a machine tool and suppresses thermal displacement of the main spindle to a low value. CONSTITUTION:Cooling liquid is circulated between a cooler 21 and a main spindle head 11 to cool a main spindle. A heat generating power of the main spindle responding to the number of revolutions of a main spindle is previously stored in a control means (CPU) 31. When a main spindle starting signal and the number of revolutions of the main spindle are received from a machine control device (MTC) 33, a heat generating power of the main spindle responding to the number of revolutions is determined. An insufficient cooling work volume due to a delay in a time in which a cooling power of the cooler 21 attains the heat generating power of the main spindle is determined. A CPU 31 controls a cooling liquid temperature by driving an inverter 23 so that a work volume equivalent to the determined insufficient cooling work volume is consecutively executed as an additional work by means of the cooler 21.

Filed: 1988-06-06
Abstract: PURPOSE:To surely detect a defect of a medium which is apt to generate a data error and to tracking error by reproducing an information track of an unrecorded medium and bringing its reproducing signal waveform and a tracking signal to analysis processing. CONSTITUTION:A laser light from a laser light source 1 is converted onto an information track which has been formed on an optical card 7 through an optical system, and a reflected light from the card 7 is converged onto a photosensor 8.

Title: Liquid crystal projector
Inventor: HAMAGISHI GORO
IPC: G03B21/00
Filed: 1990-05-28
Abstract: PURPOSE:To restrain the generation of the strain of a glass plate which constitutes a liquid crystal panel and to prevent a black brightness spot from occurring by disposing the liquid crystal panel and a polarizing plate in the glass container of a cooling device in a state where they are immersed in a cooling medium. CONSTITUTION:The liquid crystal panel 2 and the polarizing plates 5 and 6 are disposed in the cooling device 3 obtained by sealing the cooling medium 34 in the glass container in the state where they are immersed in the medium 34. The heat generated from the polarizing plates 5 and 6 and the panel 2 is transmitted to the medium 34, transmitted to a radiating fin 33 by the natural convection of the medium 34 and discharged to the outside. It is only the liquid crystal panel 2 and the liquid cooling medium 34 that exist between the two polarizing plates 5 and 6 in the cooling device 3, and the medium 34 does not disturb polarization. As a result, it is only the strain generating in the liquid crystal panel 2 because of temperature distribution that causes the black brightness spot. Therefore, the temperature rise of the liquid crystal is suppressed in virtue of the heat transmission of the cooling medium and the temperature is uniformized in the panel 2. Thus, the strain of the glass plate which constitutes the panel 2 is prevented from generating and the black brightness spot is not caused.

Title: Fuel injection control method
Inventor: KUBO SUEHIRO
IPC: F02D41/00
Filed: 1983-07-28
Abstract: PURPOSE:To assure good operability by preventing the variations of acceleration caused after a fuel decreasing treatment when a fuel returns from a fuel cut state to an original condition by controlling the amount of fuel injection to increase it by a prescribed rate after said treatment. CONSTITUTION:A control circuit 20 checks the number of counts of a rotary counter since the time fuel injection returned to an original condition if the number of engine revolutions is less than that at said fuel returning and an idle switch is turned on. And, it judges a speed regulator if the number of revolutions is less than the specified number of revolutions, e.g., 12, and if a flag is set to 1 showing wherther or not the fuel should be increased in succession to the fuel amount decreasing treatment at fuel returning after the fuel cut. In case of the speed regulator being a manual one, the amount of fuel injection at fuel decreasing control is evaluated, and an injection amount at each stage is evaluated so as to increase the injection amount stepwise at each one revolution of the rotary counter till twelve revolutions thereof from the fuel cut state. The fuel injection data are stored in RAM33, and fuel injection is controlled in another routine thereof using said data. Hereby, it is possible to make an air fuel ratio rich for preventing a surge phenomenon from being produced.
