Title: Unit control system
Inventor: HASHIZUME MUTSUMI
IPC: G06F9/46
Filed: 1987-10-28
Abstract: PURPOSE:To control a unit without executing operator's unit specification by forming a means for storing operating system (OS) identification (ID) information, a sort processing means, etc., in an area specified at the time of executing initializing processing. CONSTITUTION:At the time of generating a FORMAT command from the OS, i.e. at the time of initializing processing of a medium, a storing processing part 21 stores OS ID information in the previously fixed area of the medium. At the time of inserting the initialized medium, an information ID processing part 22 reads out the OS ID information stored in the previously determined area of the medium and decides the OS. A sort processing part 23 transfers the information to the OS in the system recognized by the processing part 22, stores the OS information in its corresponding unit control information area in a unit control table 104 and executes system sorting processing so that the OS can use the medium. Thus, unit control can be attained without executing operator's unit specification.

CONSTITUTION:When the lap between upper and lower cutter, i.e. the amount of the relative positions between the upper and lower cutters, is measured, a stand is moved to either of the right or left measuring position. Then, a minute-amount sending device 8 is operated, and a measuring piece 16 is aligned with the lowest surface of the upper cutter 13. The numerical value at this time is obtained. Then, a measuring device 11 is moved forward. Thereafter, the measuring piece 16 is lowered by operating the minute-amount sending device 8 until the measuring piece 16 contact the uppermost surface of the lower cutter. Thus, the uppermost surface is detected. After the above described operations, the detected numerical value of the measuring device 11 and the relative moved amount of the minute-amount sending device are determined. Since the relative positions of the upper and lower cutters can be found in a unit of 0.01 mm, the precise setting can be accomplished.

Abstract: PURPOSE:To execute the high accuracy by making the collector current of a first transistor larger than the value of the ratio of the product of a Boltzmann's constant value and an absolute temperature value and the product of an electronic charge quantity and an inscrted resistance value. CONSTITUTION:A resistance R1 is inserted between the base collectors of a transistor(TR)Q1 and a collector current I1 is set so as to become an inequality I.

The intersection of both becomes an action point and a constant current I4 is determined. Here, when the current ratio of a current mirror circuit 10 is dislocated, the relation of both functions complimentarily as per the above, and therefore, a dislocation quantity  I of a current can be minimized.

Filed: 1989-10-24
Abstract: PURPOSE:To prevent the generation of the shift of the rotation stop position of a type wheel by prohibiting the rotation of the type wheel at the time of the shift operation of an erasure ribbon from a use position to a retracted position. CONSTITUTION:The timing cutting off the excitation of a wheel motor 9 is set so as to cut off the excitation of the wheel motor 9 at the time t9 after time t8 when the shift-down of an erasure ribbon 19 is completed.

Title: Phase synchronizing oscillator
Inventor: OOSUMI YUUJI
IPC: H03L7/12
Filed: 1989-10-23
Abstract: PURPOSE:To freely set the level of voltage of a power supply by applying a bias voltage to a loop filter, a sweep oscillator and a sampling phase comparator from a bias circuit in the phase synchronizing oscillator using a sampling phase detector. CONSTITUTION:If synchronization is unlocked, for example, a DC component VA at the output terminal A of a sampling phase comparator 2 is 0V, a current I1 flowing to a resistor 18 through a capacitor 17 is zero and the voltage VC at a point C is zero. A bias voltage VBIAS is applied to one input terminal of an operational amplifier 15 directly from a bias circuit 13 and supplied to the other input terminal via a resistor 14 and an operational amplifier 11, respectively. Thus, even when two power supply voltages VCC, VEE are fluctuated, the current I1 is always larger than a current I2 flowing to a resistor 18 at all times. Thus, a sweep oscillator 12 stops its operation and a loop filter 4 is operated to cause synchronization.

Title: Hydraulic circuit controlling actuator by two-way control valve
Inventor: KOIKE JUN
IPC: G05D16/10
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To miniaturize a circuit and reduce price by providing a leak oil relief valve having a spring against clogging of the orifice of a poppet with hydraulic force acting on an action chamber between an actuator and a two-way control valve. SOLUTION: When a two-way control valve 3 is closed, pressure oil from a hydraulic source 1 does not act in the direction of a hydraulic motor 2 by a valve 3 and enters a leak oil relief valve 10 between the motor 2 and the valve 3 from a P port 12 before leak oil exists and it acts on the motor 2. Because leak oil acts on an action chamber 16, hydraulic force is smaller than pressing force of a spring 18 and a popped 17 opens an orifice 14, leak oil flows to a T port 11 via the orifice 14 and returns to a tank 4. When the valve 3 is opened, pressure oil of high pressure and large capacity from the hydraulic source 1 acts on the valve 10, hydraulic force becomes larger than pressing force of the spring 18, the poppet 17 closes the orifice 14 and pressure oil acts on the motor 2.  Thus, leak oil of the two-way control valve can be relieved to an oil tank by a miniaturization and at low price.

As mentioned above, the photoresist having the good photoabsorption is obtd. by dispersing the org. color matter in said photoresist, and the photoresist having various exposure depths can be formed by changing the power of radiation rays for the exposure.
