Patent JP-H06232748-A (JP)
Title: Analog/digital converter circuit
Inventor: IZUMIHARA KUNIHIKO
IPC: H03M1/36
Filed: 1993-02-01
Abstract: PURPOSE:To prevent the circuit control from being complicated by operating simultaneously all switching blocks and converting a signal of low-order depending whether number of switching blocks whose input analog signal is higher than a reference voltage is an even number or an odd number. CONSTITUTION:Switching blocks SB1, SB6, SB7, SB12 arranged in a 1st column respectively compare reference voltages V1, V7, V9, V12 with an input analog signal VIn. The results of comparison being signals S1, S6, S7, S12 are outputted to an even number/odd number discrimination circuit EOD1. Then whether or not there is an even number of signal levels being logical 1, and when the number is discriminated to be an even number, the circuit EOD1 outputs a 0 level and when the number is discriminated to be an odd number, the circuit EOD1 outputs a 1 level. Similarly the switching blocks arranged in 2nd and 3rd columns are discriminated and a discrimination result of each discrimination circuit is outputted to a low-order encoder ED1. A conversion code of low-order bits in response to the result of discrimination is obtained from the low-order encoder.

Title: Detecting circuit for out of synchronization of phase synchronizing circuit
Inventor: TAKEUCHI TAKIICHI
IPC: G11B20/14
Filed: 1987-01-27
Abstract: PURPOSE:To detect correctly out of synchronization of VFO circuit for a recording method to an extent that a PLO clock becomes >=2 data bits by comparing directly a detection timing signal issued from the timing signal for data processing and controlling which is the output form VFO circuit with a PLO clock. CONSTITUTION:The circuit is attached with a first device for forming the timing for detecting out of synchronization, and a second device 40' for checking the phase of a clock signal for a phase-locked oscillator (PLO) which is the input signal to a phase-synchronizing circuit (VFO) 20 in the detection timing to detect out of synchronization. Thus, the circuit 40' for detecting out of synchronization forms the timing for detecting out of synchronization from the data processing and controlling signal and acts to turn the error signal to '1' when the PLO clock is raised in the detection timing so as to eliminate the use of the output signal of a demodulator circuit 30' and to detect surely the out of synchronization for the VFO circuit even when the period of the PLO clock becomes larger than '2' data bits.

Title: Ignition timing control device
Inventor: FUJIMOTO TAKANORI
IPC: F02P5/155
Filed: 1980-02-08
Abstract: PURPOSE: To stabilize ignition timing during low revolution speed by delaying the properties of advancing angle obtained from the computational result of an ignition timing computation circuit for a fixed time regardless of the number of revolution at least in a low revolution region.  
     CONSTITUTION: As the time chart C illustrates, the peak potential VT 2 , when charged and discharged, is constant below the specified number of revolution N 2  regardless of the number of revolution. The potential VT 2  either clips at constant- current voltage elements or clips by the source voltage by setting a large inclination of charging and discharge m 2  and n 2 . Constant potential VT 2  makes the inclination of charging and discharging m 2  and n 2  constant. The angle of discharging is smaller as the number of revolution is reduced. With this construction, an accurate and stable ignition timing can be obtained against revolution fluctuations at least fluctuations up to the specified number of revolution N 2 .

IPC: H05B41/18
Filed: 1991-02-06
Abstract: PURPOSE:To provide a discharge lamp lighting device which is in no danger of being damaged or causing an electric shock by a starting high voltage. CONSTITUTION:In starting lighting of a discharge lamp, a monitor and control portion 5 first drives a starting high voltage generating portion 2 to apply a high voltage to the discharge lamp 3, and monitors the starting condition of the discharge lamp from a lamp current which is the output of a current detecting portion 4 and, if the start of lighting fails, redrives the starting high voltage generating portion 2 and monitors the starting condition from the output of the current detecting portion 4: the monitor and control portion 5 repeats the above sequence four times and, if even then the start fails, stops driving the starting high voltage generating portion 2 and also stops an electricity feed portion 1 from feeding electricity. The discharge lamp is thus prevented from being turned off halfway at the start of lighting and generation of the starting high voltage over a long time is prevented.

Title: Soldering method
Inventor: NAKAZONO MASAKAZU
IPC: H05K3/34
Filed: 1983-02-03
Abstract: PURPOSE:To decrease thermal impact and thermal strain and to reduce soldering time by placing a material to be soldered on a soldering part, preheating the neighbohood of the soldering part and irradiating a laser beam to the central solderin part. CONSTITUTION:Soldering parts 3a, 3b of an electronic part 4 are placed on a soldering base plate 1. IR rays 8, 10 or hot air is applied around the soldering parts to preheat the same. A laser beam 7 is then irradiated to a spot position 9 to melt solder 6 and to solder the soldering parts.

Title: Device for protecting/holding alarm
Inventor: TANAKA SATOSHI
IPC: G08B29/18
Filed: 1989-01-25
Abstract: PURPOSE:To protect and hold many alarms even when they are simultaneously generated by providing a protecting/holding device with a pulse generating circuit for supplying pulses in common to plural alarm protecting/holding circuits and processing only an input signal continued for a prescribed protection period or more as an alarm. CONSTITUTION:An alarm protecting circuit 1 receives a rectangular pulse from the pulse generating circuit 2 and sets up a period from the leading edge of the pulse up to its trailing edge as an alarm protection period. When various alarm inputs disappear within the protection period, the signal is regarded as a signal other than an alarm due to noise or the like and ignored, and when the signal is continued for the protection period or more, the signal is processed as an alarm signal to protect the alarm. An alarm holding signal forming circuit 3 forms a holding signal to hold the alarm continuously generated also after the alarm protection period and sends the formed signal to an alarm holding/ resetting control circuit 4. The circuit 4 receives the holding signal and holds the alarm, and when the alarm input disappears, controls the alarm so as to instantaneously cancel the alarm holding.
