IPC: H01J29/48
Filed: 1979-10-03
Abstract: PURPOSE:To improve the withstand voltage characteristics by employing a longitudinally laminated structure of an insulator, a resistor and an insulator for an electrode supporting structure while projecting electrodes to be applied with low or midle voltage from the resistor. CONSTITUTION:A longitudinally laminated structure of an insulator 2a, a resistor 2b and an insulator 2c is employed for an electrode supporting structure 2. Supporters 31, 41, 51 for cathodes 3, 4, 5 and portions for projecting the first, second and third grids 6, 7, 8 are projected from the insulator 2a, while portion 91 for projecting the fourth grid 9 is projected from the resistor 2b and portions 101, 111 for projecting the fifth and sixth grids 10, 11 are projected from the insulator 2c. Then 25kV, and 500V are applied through a spring 15 and a stem lead 18. Consequently 7kV is applied on the thrid and fifth grid electrodes, and instable charge in the proximity of low voltage electrode flows through the resistor 2b into the fourth grid resulting in the improvement of withstand voltage.

Title: Controller for glow plug
Inventor: DANNO YOSHIROU
IPC: G05B11/16
Filed: 1977-10-21
Abstract: PURPOSE: To judge the temperature of a plug to properly control the same by dedecting either the resistance of a switching element or the pressure drop of the plug which is intermittently supplied with an electric power through the switching element.  
     CONSTITUTION: An oscillator 5 oscillates in response to the conduction of a key switch 4 so that the resultant signals are shaped by ashaping circuit 6 and are fed intermittently to the base of a transistor 3 forming a switching element. When this element 3 is connected, each glow plug 2 is preheated by a battery 1. On the other hand, when the element 3 is rendered inconductive, the voltage at a resistor 7 and the plug 2 is fed through an amplifier 8 to a comparator 9 and a memory circuit 11 so that it may be compared with a reference value thereby to judge the temperature of the plug 2 from the voltage drop. When the temperature detected is lower than the preset value, the time for the element 3 to be conductive is elongated to preheat the plug 2

Title: Electronic analog display time piece with solar battery
Inventor: YAMAGUCHI YOSHITO
IPC: G04G19/00
Filed: 1981-08-12
Abstract: PURPOSE:To enable the indication of the conditions of batteries with a simple construction by controlling the number of steps of the time indication with multi- step radial segments according to the conditions of a solar battery and a secondary battery charged therewith. CONSTITUTION:According to detection outputs of a generation state detection circuit for a solar battery depending on voltage value of the solar battery and a secondary battery in a power supply circuit and a charge state detection circuit for the secondary battery, a gate group is controlled so that segments 4a-4d making up a radial segment for the time indication, extending from the inside to the outside, will be selected from the inside. With such an arrangement, the time will be indicated in such a manner that a pointer is stretched according to the conditions. This enables the indication of following various conditions of the batteries with a simple construction eliminating any special display section: there is no irradiation of light on the solar battery, hence leaving the power generation at rest, the secondary battery is not charged sufficiently despite operation of the solar battery and both batteries are working properly.

Title: Bending method of steel pipe
Inventor: NAKAYAMA YOSHIO
IPC: B21D7/16
Filed: 1983-07-14
Abstract: PURPOSE:To bend a steel pipe to have the uniform strength after bending by heating the steel pipe to the temp. above the A1 transformation point and bending the steel pipe. CONSTITUTION:Hot bending of a steel pipe is accomplished by heating the steel pipe within the range where the A1 transformation point in the phase diagram of steel or below or the temp. lower by 50 deg.C than the A1 transformation temp. is made the upper limit temp. and the recrystallization temp. of the steel is made the lower limit temp. and bending said pipe. The heating temp. distribution from the bent part of the steel pipe to the straight pipe part which is not bent is then made the temp. distribution from the annealing temp. to a room temp. Thus the part where the temp. is above the A1 transformation temp. and just below the A3 transformation temp. does not exist and therefore the uniform strength is obtd. to the steel pipe after bending and cooling.

Abstract: PURPOSE:To prevent a magnetic disk control device from the reduction of performance by automatically correcting an interruption signal sending timing correspondingly to the response speed of a master device. CONSTITUTION:When a data read/write instruction from/to a magnetic disk device is received by the magnetic disk control device 4 from the host device 1, a control means 7 temporarily releases coupling with a common bus 11 so as to position a head on a specified track of the device 9, and after the end of the positioning of the head, interrupts the host device 1 through the bus 11 at initializing timing. A counting means 8 counts up the number of sectors based on an index signal and a sector signal sent from the devices 9, 10 and the means 7 calculates the time required up to an objective sector for writing/ reading data based on said counted value and interrupts the host device 1 at the fixed timing before the arrival of the heat at the sector. At the time of response of the host device 1, the means 7 inspects the timing, and if the response is fast or slow, corrects the timing so as to be the optimum timing until the succeeding instruction processing.

Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To provide a facsimile equipment with excellent operating convenience for the user to which setting contents like an exclusive facsimile equipment are made simply with a simple operation even if the facsimile equipment is a function-shared facsimile equipment. SOLUTION: When a document bank has been linked with a designated department code (S13:Y), the linked band is assigned to operating knobs of an operation display section 2 (S14).

Title: Method and apparatus for detecting discharge capacity of battery and controller for car battery
Inventor: IMAI ATSUSHI
IPC: G01R31/36
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To make detection accuracy of a discharge capacity higher by reducing the influence of charging polarization and changes with passage of time in a lead and acid battery. SOLUTION: A battery voltage Vbat, a current value I, a regulator voltage Vreg, a battery temperature T are sampled (S1) by a prescribed sampling period Δt. A present discharge capacity Cd(t) is computed from current integration (S4, S5). Here, a charging efficiency η based on the discharge capacity Cd and the battery temperature T detected last time are used, if the battery is in the course of charging (S2, S3). If it is in the course of constant voltage charging, whether the charge rate with time (dI/dt) of the charging current value I has become a prescribed value k or less is decided (S5, S6). If dI/dt is not larger than a prescribed value k, a discharge capacity Cdres is found on the basis of data which are stored in memories, from the current value and temperature T. The value of the discharge capacity Cd is corrected to Cdres (S9).  On the basis of the detected capacity Cd, the output control of an alternator/regulator 3 is performed (S10-S13).

Title: Amplifier circuit
Inventor: TAMURA YOSHIYUKI
IPC: H03F1/32
Filed: 1983-07-14
Abstract: PURPOSE:To execute an amplification of a high quality by constituting so that a distortion rate does not become large even if an input signal level of an amplifier circuit becomes large. CONSTITUTION:An output signal level vo is compared in both a comparing circuit 3 in which it is compared with an output potential VCC2 of a reference potential circuit 5, which has dropped by a prescribed voltage from a high potential side power source VCC1 of an amplifier circuit 2, and a comparing circuit 4 in which it is compared with an output potential VEE2 of a reference potential circuit 6. If there is an output of one of the circuits 3, 4, a controlling circuit 7 for outputting a control voltage VG brought to a DC ratio operates, and an amplification factor of its amplifier circuit 2 is controlled by this VG. As a result, the output level becomes such an output waveform as saturated between the potential VCC2 and the potential VEE2. When an input level vi becomes gradually large, as for the output level vo, the waveform is not clipped but suppressed at a level B, therefore, a distortion rate does not become large.
