Title: Data logger device
Inventor: KANEKO TOMONORI
IPC: G08C15/00
Filed: 1989-07-17
Abstract: PURPOSE:To prolong the life of a product while maintaining the satisfactory convenience of use by dividing a data logger into an on-line part and an off-line part, accumulating data in a main memory for the prescribed number of days for the off-line part and electrifying the on-line part only at a necessary time. CONSTITUTION:The data logger is divided into an on-line part 33, which is always energized, and an off-line part 34 to be energized only at the necessary time. The on-line part 33 periodically fetches signals by an analog input card 28 and a digital input card 29 of a process input/output device 26. These input signals are accumulated in a main memory MS 20 of a controller 18 for the prescribed number of days. Next, the power source of a personal computer 1 in the off-line part 34 is turned on and a keyboard 13 is operated. Then, a slip printing command is applied to an MPU 5. The MPU 5 processes daily report data, which are accumulated in the main memory MS 20, through communication 12 and 23 according to the program of a main memory 10. Thus, it is enough for the off-line part 34 to supply power only at the necessary time and the life of the product can be prolonged while maintaining the satisfactory convenience of use.

Title: Still picture recorder
Inventor: NAGANO MASAHIKO
IPC: H04N5/781
Filed: 1982-10-22
Abstract: PURPOSE:To obtain pictures of high quality with a small still picture recorder, by performing record/reproduction so as to arrange properly the phases of a horizontal synchronizing signal and a center carrier wave between tracks corresponding to the 1st and 2nd fields. CONSTITUTION:In a record mode a reference phase signal on an auxiliary track TP is reproduced by a magnetic head hP and sent to a phase comparator 4 to be compared with the reference phase signal of a reference signal oscillator 5. Then the signal corresponding to the phase difference is sent to a voltage control oscillator VCO6. The VCO6 has its oscillation frequency corresponding to the rotary phase of a rotary magnetic disk and sends a carrier signal to a phase modulator 8. While a luminance signal Y undergoes the phase modulation under the control of a vertical synchronizing signal through a 1/2HOLD in the 1st field and directly from the modulator 8 in the 2nd field respectively. Then the signal Y is supplied to magnetic heads h1 and h2 respectively in accordance with the 1st and 2nd fields. Then horizontal synchronizing signals are arranged properly in the radius direction, and at the same time the phase of luminance signals are also arranged properly between adjacent tracks. In such a way, both horizontal synchronizing signals and luminance signals are recorded and then demodulated approximately in an opposite way.

Abstract: PURPOSE: To effectively utilize a hydraulic pump for other purposes by connecting the neutral position of a leveling valve provided between a suspesion cylinder and a pressure accumulator to another hydraulic device and switching this valve to a vehicle height detector controlled by a timer.  
     CONSTITUTION: A hydraulic detection sensor 18 detects the vacant or loaded state of a vehicle, operates a timer 16 and closes a position sensor 14. The sensor 14 detects the relative position between an axle 5 and an automotive body 6, switches a leveling valve 8 to normal or reverse position via a solenoid air valve 12 and a control cylinder 11, and starts the leveling operation. After the time set by a timer 16 is elapsed, the valve 8 is neturned to its original neutral position. Thereafter, hydraulic pressure may be used for another hydraulic device. The elevational movements of the axle 5 are absorbed by a pressure accumulator 10. With this structure, the hydraulic pump is used ony at the time of operating vacant and loaded vehicles, but may be used for the other hydraulic device so as to save the energy.

Inventor: KAMATA MASAHIKO
IPC: H05B41/24
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp lighting device that prevents striation with a simple structure. SOLUTION: An oscillator 13 is oscillated, a diode D1 comes into a reverse blocking state when a capacitor C1 is charged so that the capacitor C1 is charged only based on the resistance value of a resistor R1, and the diode D1 conducts current when the capacitor C1 is discharged so that the capacitor C1 is discharged based on the combined resistance value of the resistor R1 and a resistor R2. In the case that the capacitor C1 is discharged, because the resistor R2 is connected in parallel with the resistor R1, the combined resistance is lowered, so that the discharge time becomes shorter than the charge time. A driving circuit 15 turns on and off field effect transistors Q1, Q2 by setting their on-time different from each other so as to make them asymmetrical in terms of polarity.  An inverter circuit 11 converts the direct current of a D.C. power source E into a high-frequency alternating current, equalizes lamp currents by using a balancer L3 and lights fluorescent lamps FL1, FL2 while preheating filaments FL1a, FL1b, FL2a, FL2b of the fluorescent lamps FL1, FL2.

Title: Fm demodulator
Inventor: NISHIWAKI MASAHARU
IPC: H03D3/24
Filed: 1981-11-18
Abstract: PURPOSE:To improve the threshold characteristics, by providing loop filters having broad and narrow band characteristics in a PLL circuit and taking the synthesized output of both as a control signal. CONSTITUTION:A loop filter 6 receives an output of a phase comparator 2 and gives a demodulated output of an input FM signal to a terminal 5. This loop filter 6 controls a voltage controlled oscillator 4, which has a broad band characteristics so as to follow an FM signal inputted to a terminal 1. A loop filter 7 has an amplifier 13 with a large gain and the DC open loop gain is sufficiently large with narrow band. Even if noise is inputted and the PLL is unlocked, when a weak signal is inputted to the phase comparator 2, since the voltage controlled oscillator 4 is locked to a center frequency in a long time constant, the threshold characteristics can be improved.

Title: Eye inspector
Inventor: KOBAYAKAWA YOSHI
IPC: A61B8/10
Filed: 1990-07-13
Abstract: PURPOSE:To achieve automatic identification of right and left eyes when inspected even in an ophthalmological apparatus of a hand carrying type or without sliding base by measuring a level, intense or weak, of a reflected light of a luminous flux emitted from a light source which lights a side part of a signal eye to identify the right and left eyes. CONSTITUTION:When an eye inspecting axis X aligns a left eye EL, lighting areas a and Db of light sources 2a and 2b are given on the right and left. A luminous flux from the light source 2a is intense in reflection as hitting a nose of a person S to be inspected and hence, a relatively large signal is obtained with a photo detector 3a. On the other hand, the luminous flux from the light source 2b becomes weaker as it is off a face of the person S to be inspected and hence, a relatively small signal only is obtained with a photo detector 3b. Thus, by comparing the size of output signals of the photo detectors 3a and 3b, that the left eye EL is inspected can be identified.
