Patent JP-H08236844-A (JP)
Title: Laser equipment
Inventor: OGAWA MAKOTO
IPC: H01S3/042
Filed: 1995-02-23
Abstract: PURPOSE: To make the temperature of secondary side cooling water fit to the temperature of primary side cooling water, by performing temperature control, in the manner in which the reference value of temperature is changed according to the duty of switching time of a solenoid valve on the primary side cooling water supply side of a heat exchanger. CONSTITUTION: A heat exchanger 50 is connected with primary side cooling water FW via a solenoid valve 72. Secondary side pure water CW is made to circulate around the heat exchanger 50, a tank 56 and a chamber 14 by a pump 52. A temperature detection signal St of the pure water CW in the tank 56 is detected by a temperature sensor 64 and a temperature detection circuit 66. The signal St is compared with a reference value Pt. When the signal St is lower than the reference value Pt, the solenoid valve 72 is closed. When St is higher than Pt, the valve 72 is opened. Thus the temperature control is performed, and the reference value Pt is set simultaneously. Firstly, the reference value Pt is set as an initial value P0 , and the duty is obtained on the basis of the switching time of the valve 72. The duty is compared with the previously set value.  In the adequate case, the reference value Pt is kept constant. In the high case, the reference value Pt is increased. In the low case, the reference value Pt is decreased.

Title: Frequency detector
Inventor: ANDO HISATAKA
IPC: G09G5/18
Filed: 1988-03-14
Abstract: PURPOSE:To accurately detect frequencies even if the frequencies change over a wide range by adding or subtracting a constant to or form a set period until the difference between the count value of the reference clock between the N- periods of a horizontal synchronizing signal and the set period decreases down to a constant alpha or below. CONSTITUTION:The count value (x) by a counter 18 of the reference clock F of the N-periods is NTHfCK when the frequency of the reference clock F from an oscillator 17 is designated as fCK and the period of the horizontal synchronizing signal HD as TH. The constant alpha of a setting circuit 22 is added to or subtracted 21 from the set period (y) when the difference between the count value (x) of the output of an arithmetic comparator circuit 20 and the (y) decreases down to the constant beta of a setting circuit 25 or below by the output of a comparator circuit 24 and, therefore, y-x=NTHfCK holds at the error + or -beta or below. Since N and fCK are known, the approximate value of the period TH of the horizontal synchronizing signal HD is obtd. The frequency fH of the horizontal synchronizing signal is the frequency TH and the hH is determined. The stable detection value is thus accurately obtd. even if there is the drop-out of the pulses in the horizontal synchronizing signal HD.

Title: Printer
Inventor: YAGI TAKASHI
IPC: B41J2/28
Filed: 1979-05-17
Abstract: PURPOSE:To accomplish high speed printing with a limited power consumption through reciprocation of the attraction member (composing the magnetic circuit) so connected to the mechanical vibration generating section of the printer that the printing element parallel to the attraction member connects with the electromagnetic action body which is to contact the attraction member when the machine is at rest. CONSTITUTION:The attraction member making up the magnetic circuit with the electromagnetic element of the printer is connected to the mechanical vibration generating section 14 so that a straight reciprocation is made so as to as to have the printing element 10 almost parallel to the attraction member 6 connected with the electromagnetic action body 7 which is to contact the attraction member when the machine is at rest. This causes the attraction member to be forcibly reciprocated by the vibration generating section 14. However, as the electromagnetic circuit fails to be formed unless the electromagnetic element is not energized, the attraction member acts freely while as soon as the electromagnetic element is energized, the attraction member and the electromagnetic action body acts as the components of the magnetic circuit. The electromagnetic action body performs printing following the attraction member 6. Therefore, the vibration generating section 14 provides the main energy for the printing reducing the power consumption.
