Title: Pressure drive type power wrench
Inventor: KAARU BOIKE
IPC: B25B21/00
Filed: 1991-01-11
Abstract: PURPOSE: To provide a pressure-operated power wrench that needs shorter time in rotating bolts and smaller power of its pressure assembly. CONSTITUTION: Two pistons 38 and 41 disposed in mutual telescopic relationship abut against a pressure member 26 to pivot a lever 18, which is coupled to a bolt head to be rotated by way of an annular member 14. In the working stroke, the travel of the first piston 38 is limited when it abuts against an abutment part 46, while the second piston 41 moves on. The largest part of the working stroke is made exclusively by the second piston 41 and is thus performed with low hydraulic throughput. When the force of the second piston 41 becomes insufficient, the working stroke is made by both pistons 38 and 41 over shorter piston travel.

Title: Controller for feedwater flow rate
Inventor: KIYOFUJI MITSUGI
IPC: G05D9/00
Filed: 1989-01-11
Abstract: PURPOSE:To suppress the level fluctuation of a container by integrating the deviation signal between the container level and the set level value via an integrator having the increased input gain, applying the limitation of higher/lower limit levels to the integration output, and adding this output to a feedwater control valve opening amount request signal as a feedwater control valve opening amount correction signal. CONSTITUTION:A deviation signal 11 between the container level and the set level value is multiplied by a large input gain via a proportion unit 1 and then integrated by an integrator 2 for acquisition of a feedwater control valve opening amount correction signal 13 which actuates early a feedwater control valve 16 over the blind sector width of the valve 16 even with a minute level deviation. The signal 13 received from the integrator 2 is limited down to the small value by such an extent that never deteriorates the stability of the container level based on the upper/lower limit set value 3. Thus a feedwater control valve opening amount correction signal 14 is obtained and sent to an adder 6. Then the signal 14 is added to a feedwater control valve opening amount request signal 12 and sent to a feedwater control valve 15 to control this valve 15. Thus it is possible to suppress the undesired fluctuation of the container level in a normal operation state.

Title: Bar code reader
Inventor: ISHII MITSUHARU
IPC: G06K7/10
Filed: 1986-01-10
Abstract: PURPOSE:To form an economical bar code reader by omitting a light emitting sensor and a complicated control circuit. CONSTITUTION:Laser beam transmitted from a light source 9 is reflected by mirrors 10 and 12, diffracted by a hologram disk 14, and reflected by mirrors 14 and 15 and transmitted from a scan window as an arrow E shows, thereby reading a bar code printed on passing goods. After the prescribed time expires, a pulse transmitted by a monostable vibrator 16 stops, and a transistor 17 is turned off. Accordingly an electromagnet 18 stops its attraction of the mirror 10, which returns to its original position as an arrow B shows. As a result the laser beam transmitted from the scan window disappears, as the arrow E shows, whereby double-reading can be prevented even if an operator moves goods in the reverse direction.

Title: Dc linear motor
Inventor: NISHIZAWA TAKASHI
IPC: H02K41/035
Filed: 1991-01-16
Abstract: PURPOSE:To obtain an inexpensive miniature DC linear motor which exhibits brake function even under unexpected conditions, e.g. power interruption, by disposing a brake unit on a line so that it is juxtaposed to a thrust generating exciting coil. CONSTITUTION:Brake exciting coils 10a, 10b are excited simultaneously under normal operation. Consequently, attraction force functioning between the exciting coils 10a, 10b and an iron plate 11 causes a brake pad 12 to be released from a field permanent magnet 3 thus ensuring an air gap. When the operation of DC linear motor is interrupted, the brake exciting coils 10a, 10b are brought into no-excited state and released from the iron plate 11. A spring 13 carried on the iron plate 11 causes the brake pad 12 to be pressed against the field permanent magnet 3 thus keeping the runner 9 of the DC linear motor at an original position.
