Title: Power unit for laser
Inventor: SASAKI NORIAKI
IPC: H01S3/097
Filed: 1995-11-06
Abstract: PROBLEM TO BE SOLVED: To reduce the switching loss of a power unit for laser by providing an inverter control means which controls an inverter section so that the rise of the output current of the section can be delayed from that of the output voltage of the section. SOLUTION: A frequency command means 10 subtracts a set current value from a prescribed voltage value by means of a subtracting circuit 18 and outputs a signal which reduces the switching frequency fs of an inverter section to a voltage-controlled oscillation circuit 16 in accordance with the increase of the difference. An upper/lower-limit limiter circuit 19 sets the upper and lower limit values of the frequency fs and, on the other hand, outputs a signal which changes the frequency fs in accordance with the difference. Since the output of the limiter circuit 19 is inputted to the oscillation circuit 16 as a frequency command signal which commands the switching frequency fs of the inverter section, the frequency fs is changed in accordance with a discharge current set by means of a current setting means 8. Therefore, the rise of the output current of the inverter section is delayed from that of the output voltage of the section and the switching loss of a power unit for laser can be reduced.

Title: Display device having memory type display section
Inventor: OOSHINO SHIGETO
IPC: G09G3/38
Filed: 1987-11-16
Abstract: PURPOSE: To visually decide that the power source is turned on and off by providing a power source control part which detects the on/off state of a power source disconnecting means and controlling a display control part and the power source part by this power source control part. CONSTITUTION: When the power source disconnection means 15 turns off, the power source control part 14 sends a sign A to a display control part 12 through a control line 17, and consequently end display data is sent out to the storage type display part 11 through a control line 19. The display control part 12 after sending data out to the storage type display part 11 sends an end sign to the power source control part 13 through the control line 17, the power source control part 14 once receiving this sign sends a sign B through a control line 16 so that the power source part 13 turns off the power source, and the power source part 13 turns off the power source on receiving the sign B. The end display data is display data for erasing the display of the whole screen of the storage type display part 11 and a message, etc., indicating the power- OFF state.  Consequently, the power-OFF state can visually be decided at the power-OFF time, so the operability is improved and misoperation can be prevented.

Title: Single crystal pulling apparatus
Inventor: MATSUYAMA SHUNICHIRO
IPC: C30B15/00
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To speed up the growth of a single crystal and also to lengthen the lifetime of a radiation shield by forming beveled part so as to reduce the diameter of cylindrical part of the radiation shield having the shape of a frustum of a cone and having an opening for a single crystal to pass through. SOLUTION: When a single crystal pulling apparatus has a three-layered radiation shield 10 including a heat-insulating material installed above a silicon melt surface 13 for the purpose of effectively shutting out primary radiant heat from the melt 3 to a single crystal 20, of retaining the temperature of the conical part of the shield 10 so as to be low and of effectively shutting out secondary radiant heat from the conical part to the single crystal 20, the temperature gradient of the single crystal 20 in its axial direction increases and high-speed crystal pulling is made to become possible at high rate of single crystal.  Effective exhaust is carried out by beveling or rounding the outskirts of the bottom of the shield 10 (e.g. by forming a cylindrical arc) so as to enlarge the breather path, and therefore it is possible to prevent SiO2 from sticking to the shield 10 and also to prevent the SiO2 from dropping from the shield 10 to the melt surface 13 thus inducing the dislocation.

Abstract: PURPOSE:To obtain such a sense as viewed through glass having a wavelike undulation on the surface by giving a latch enable signal of parallel data to a P/S converting part from a timing signal generator and performing a special effect. CONSTITUTION:Data read out of a memory 1 is brought to parallel/serial conversion by a P/S converting part 3 in accordance with a clock (a), a strobe signal (c), address data (g) and a latch enable signal (d) from a timing signal generator 4. The data from the memory 1 is written in an (n)-stage register (n: an integer) at the time when the latch enable signal (d) is H by synchronizing with the strobe signal (c), and not written at the time of L. Subsequently, an address decoder 8 decodes the address data (g), and switches a selector 7. As a result, the data in the (n)-stage register 6 is selected successively such as #1-#(n) in the selector 7, and outputted from a flip-flop 9 by synchronizing with the clock (a). In such a way, such an atmosphere as frozen, viewed through ice or glass can be generated.
