Title: Manufacture of fresnel lens
Inventor: YAMAMOTO YOSHIHARU
IPC: B29C61/00
Filed: 1980-04-14
Abstract: PURPOSE:To easily manufacture large-size Fresnel lens having good flatness by a press molding using molds consisting of a convex mold to form the mother mold size of Fresnel lens having a high releasing resistance and a concave mold facing the convex mold. CONSTITUTION:A wholly convex Fresnel lens mother mold is carved in a mold 8 to form the lens face of Fresnel lens, and concave face is carved in the counter mold 9 in such a way as to match the said mold 8. To these molds 8 and 9, a pressure is applied in the direction of arrow 10 at a proper temperature in order to press a transparent resin sheet, e.g., of vinyl chloride or acrylate, between them. Thus, in releasing the molded Fresnel lens from the molds, warping caused by differences in its releasing resistance can be prevented within such a range that no trouble arises when being used.

Title: Laser driver, driving method and imaging system
Inventor: KAWAKAMI TAKAYUKI
IPC: H01S5/0683
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To prevent faint emission of light due to bias current from an undriven laser emitting means when a plurality of laser emitting means are driven sequentially for automatic power control(APC) operation and the quantity of light is detected by single laser monitor means in a structure for feeding the plurality of laser emitting means individually with a bias current and a pulse current. SOLUTION: At the time of driving a plurality of laser emitting means 34, 35 sequentially and continuously, bias current supply to undriven laser emitting means 34, 35 is interrupted. Since bias power supplies are slow starter power supplies which can not be switched at high speed, dummy power supplies 42, 43 for canceling the bias current are connected with the bias power supplies 38, 39 while being switched.

IPC: B60L15/20
Filed: 1980-04-18
Abstract: PURPOSE: To miniaturize the ATC device by a method wherein discrimination of ATC signal and comparison of speed are performed in one device.  
     CONSTITUTION: A multifrequencies generation circuit 18 outputs the standard frequency in order to a multicomparator 19 conforming to data for the generation of the standard frequency being inputted in order from a memory 17 with each time slot. While an input circuit 16 outputs the ATC signal received by a receiving antenna 10 to the multicomparator 19 during this time slot. Therefore the multicomparator 19 compares the ATC signal with the standard frequency, and inputs thus obtained result to the memory 17. In the next time slot, the multifrequencies generation circuit 18 outputs limit speed frequency corresponding to the discriminated result, while the input circuit 16 outputs train speed frequency applied from a tachometer generator 10. Accordingly the multicomparator 19 compares the train speed frequency with the limit speed frequency, and outputs thus obtained result to an output circuit 20.

Abstract: PURPOSE:To increase a carrying stroke and improve the positioning accuracy of parts by moving a crossfeeding screw, to which a parts pinching device is installed freely to move, against a pair of parallel feeding screws with a nut so as to move the parts pinching device. CONSTITUTION:When a motor 16 is rotated to the arrow A direction, a first feeding screw 21 is rotated to the arrow A direction, and furthermore, a second feeding screw 22 is rotated to the arrow A direction through a wrapping and transmitting member 25. Consequently, a first and a second nuts 31, 32 move a nut 33 of a third feeding screw 23 to the arrow X1 direction smoothly at high speed. When a motor 18 is rotated to the arrow B direction, the third feeding screw 23 is rotated to the arrow B direction to move the third nut 33 to the Y1 direction. Consequently, a parts pinching device installed to a head fitting plate 34 is moved to the X1, Y1 direction. When the motors 16, 18 are respectively reversed to the C, D directions, the parts pinching device is moved to the reverse X2, Y2 direction. With this structure, a carrying stroke can be increased and the positioning accuracy can be improved.

Title: Heat-treatment of semiconductor device
Inventor: HIRAO TADASHI
IPC: H01L21/22
Filed: 1983-03-26
Abstract: PURPOSE:To protect semiconductor substrates on a boat in a furnace from being heated excessively or insufficiently according to their position by controlling the desired heat-treatment temperature when the semiconductor substrates are inserted into the furnace. CONSTITUTION:When semiconductor substrates 5 begin entering into a furnace, the set- point temperature at an entrance 6 of the furnace is ascended to be higher than the desired treatment temperature. Although the temperature of the furnace begins descending due to the cooling effect, because the difference between the furnace temperature and the set-point temperature becomes large in a short time, the maximum electric power for heating the zone of the furnace is applied quickly to prevent the furnace temperature from descending. Even if the furnace temperature begins ascending from the lowest, because the difference between the furnace, temperature and the set-point temperature is sufficient, the heating electric power, large enough to recover the furnace temperature quickly, is applied. With this constitution, the temperature of the semiconductor substrates entering into the entrance 6 of the furnace becomes nearly the same as the determined temperature when the boat 4 enters into the furnace completely. On the other hand, the temperature of the substrates 5 enter into the innermost recess of the furnace 3 reaches the determined temperature faster but large over- shooting are avoided.

Abstract: PURPOSE: To increase the arithmetic processing speed for a slave processor by omitting a process where an unexected instruction is read again out of a memory and then interpreted. CONSTITUTION: When a master processor 2 reads an instruction out of an instruction memory 1, an instruction interpretation part 21 interprets the read instruction. If this instruction is not executed, the number of this instruction is stored in an interface register 22. Then the processor 2 applies an interruption to a slave processor 3 and interrupts its processing. The processor 3 takes the number out of the register 22 for the instruction that could not be executed by the processor 2 and instructs an executing module specifying part 32 to specify the head address of an executing module which is stored in an execution instruction table 31 in response to the instruction number that is taken out of the register 22. Then the processor 3 carries out the specified executing module.

IPC: H04N5/44
Filed: 1995-03-10
Abstract: PURPOSE: To stably operate a frequency control loop without causing malfunction for detection of a weak electric field in the case of non-signal channel reception or VTR reproduction. CONSTITUTION: A synchronizing separator circuit 13, a phase detection circuit 14, an oscillator 15, and a horizontal system count-down circuit 16 form a horizontal synchronizing frequency control loop. A secondary differentiation circuit 12 obtains the secondary differentiation output of a video signal. A horizontal system count-down circuit 16 obtains a mask pulse for a pattern period and a vertical system count-down circuit 17 obtains a mask pulse for a vertical period. When noise at a position of a DC level of a horizontal synchronizing signal exceeds a threshold level, a noise detection circuit 18 provides a noise detection signal to a weak electric field detection logic circuit 23.  The weak electric field detection logic circuit 23 decreases the detection output of the phase detection circuit 14 when a horizontal locking is set and only when a standard vertical synchronizing signal is received in the case of high noise level to suppress horizontal jitter.
