Title: End pumped solid-state laser
Inventor: SUMIYA MINORU
IPC: H01S3/06
Filed: 1992-07-20
Abstract: PURPOSE:To suppress the fluctuation of the output, which is generated with an end-pumped solid-state laser that generates an inner-resonator type second higher harmonic. CONSTITUTION:An end-pumped solid-state laser, which generates an inner- resonator type second higher harmonic, is constituted of an Nd:YVO4 crystal 1a, which is a uniaxial solid-state laser crystal, a KTP crystal 2a, which obtains the second-kind phase matching, and an output mirror 3. A (c) axis of the crystal 1a is orthogonal to the axis of a laser resonator. An angle theta of a wedge satisfies tan<-1>{lambda/DELTAn (D-d)}<theta<tan<-1>{(lambda/4)/DELTAnd}. The effective diameter in the direction, where the thickness of the crystal 1a changes, is made to be D, and the diameter of the oscillating beam at the position of the crystal is made to be (d). The difference in retardations of the crystal at a position, which is separated by D-d, becomes 2pi or more. This condition is satisfied. When the crystal 1a is moved orthogonally with respect to the axis of the laser resonator within the range of D-d, the light polarizing state in the resonator can be freely controlled. The fluctuation of the output can be suppressed at one or more points.

Abstract: PROBLEM TO BE SOLVED: To perform recording and erasion to a polarization address type recersible liquid crystal recorded by the use of a general non-polarization optical write-in system by making a polarizing element also function as an optical polarizing means used for optical write-on or erasion. SOLUTION: The longitudinal direction of a recording medium 11 (aligned with the direction of the transmission axis of an upper polarizing plate) is defined as a direction 12, a direction perpendicular to the longitudinal direction 12 and parallel with the direction of the transmission axis of the lower polarizing plate is defined as a direction 13 and a direction deviated from the directions 12 and 13 by 45 deg. respectively is defined as a direction 14. In a state where an upper polarizing plate 5 is removed, all the surface of the medium 11 is previously irradiated with polarized light whose polarization direction is the direction 14. An irradiation wavelength region is set within a range where the orientation of the molecular axis of a diachroic compound is changed. Since the orientation direction of liquid crystal becomes 45 deg., light is transmitted ion accordance with the degree of the retardation of a liquid crystal layer 8. By the irradiation of light in the wavelength region that the molecular axis of the dichroic compound is changed by using a pen light in such a state, liquid crystal molecules at the irradiated part are oriented in the direction 13, so that a write-in part becomes dark.

Title: Inverter of gate turn-off thyristor
Inventor: KURODA SANSHIRO
IPC: H02M7/515
Filed: 1984-09-14
Abstract: PURPOSE:To protect a GTO by connecting a resistor in series with a GTO, thereby suppressing a shortcircuiting current in the simultaneous firing error operation of the GTO to a low value. CONSTITUTION:A resistor 11 is connected in series with a GTO2, and a resistor 12 is connected in series with a GTO3. When a firing signal is erroneously input simultaneously to the GTOs 2, 3, the GTOs 2, 3 are conducted, but the shortcircuiting current at this time is suppressed by the resistors 11, 12 to a controllable current value or lower of the GTOs. If the shortcircuiting current is detected by a current transformer 7 and compared with the set current value of an overcurrent detector 8 and the detected current value is larger than the set current value, an OFF signal is applied to the gates of the GTOs 2, 3.

Title: Vector processor
Inventor: KAJI NAOTO
IPC: G06F15/78
Filed: 1986-08-19
Abstract: PURPOSE:To improve the performance of a vector processor by producing an interruption in case the number of data to be processed by a vector instruction is smaller than a certain value and at the same time the data length of the next instruction is smaller than the value that can be processed with a single instruction and then replacing the part where said interruption is produced with a scalar instruction. CONSTITUTION:A comparator 16 compares the data length set at a vector length register 13 and the reference length shown by a reference length register 14. A comparator 17 delivers value '1' when the value of a maximum length register 15 which holds the maximum vector length that can be processed with a single instruction is smaller than the value received from a selector 12 of a control part 1. An AND circuit 22 of an interruption generating circuit 30 sends the value '1' to a control part 3 in case an instruction having the vector length smaller than the maximum set length is received after an instruction having the vector length smaller than the reference length. Thus the circuit 22 produces an interruption and this instruction is carried out by a scalar operation.

Filed: 1981-11-30
Abstract: PURPOSE:To perform high-precision TIG welding by connecting a capacitor to an output termina and removing a ripple of a welding current, and thus eliminating uncomfortable sound during arc generation. CONSTITUTION:When a welding current flows, a current relay 22 is energized to connect the plus electrodes of a capacitor 21 to the output side of a DC reactor 4 through the contact of the current relay. Before the current relay 22 is energized, the capacitor 21 is charged to a power source voltage by a DC power source 2 through the contact 23 of the relay, so once the relay 22 is energized, an external load is connected in parallel to the output terminal, so that while no large current flows to the capacitor 21, there is no decrease in supply current to the external load. During welding, a control circuit 9 receives a signal from a current detector 5 to sends an on-off signal to a transistor 3 so that the peak value of a welding current is held constant. A generated ripple is removed through the filter operation of the DC reactor 4 and capacitor 21.
