IPC: G02B5/32
Filed: 1994-08-22
Abstract: PURPOSE: To clearly discriminate the copy made by means of a copying machine by combining both the pattern in which two kinds of picture pattern elements having the directions of diffraction grating different by 90 degrees each other are combined, and the pattern in which the directions of the picture pattern elements have been turned by 90 degrees respectively are combined. CONSTITUTION: A diffraction grating pattern, is provided with a pattern A in which a letter 1 having a direction of 90deg. and a background 2 having a direction of 0deg. both having the same space frequency of a diffraction grating are combined, and a pattern B in which a letter 3 having a direction of 90deg. and a background 4 having a direction of 0deg. are combined. In the other part except the above, considering the visual effect, either of the dot angle constituting the diffraction grating or the space frequency, or both of them may be delicately changed. Thus, even if a copy is made by a monochromatic copying machine or by a color copying machine, the copying mode by means of the combined pattern A and the copying mode by means of the combined pattern B are clearly different from the way of seeing of the actual combination of A and B by means of the naked eye.

Title: Excess current protection circuit for power transistor
Inventor: ICHIJO MASAMI
IPC: H03K17/08
Filed: 1986-08-21
Abstract: PURPOSE:To surely prevent a power transistor from being damaged by an excess current due to the short-circuit of load, etc., by setting the clamping voltage of a snubber circuit below the potential of a DC power source, before the power transistor is turned off at time of generating the excess current. CONSTITUTION:When an ON signal is supplied to the power transistors Q1 and Q4, and the short-circuit of the load is generated, an ignition signal is supplied to thyristors Th1 and Th4, before the transistor Q1 is turned off. The terminal voltage of snubber capacitors CS1 and CS4 is equal to a DC power source voltage Ed until then, however, discharge to the terminal voltage Ed/2 of capacitors C1 and C2 is generated. By turning off the transistor Q1 at a time when the terminal voltage of the snubber capacitors CS1 and CS4 arrives at the Ed/2, the voltage between the collector and the emitter of the transistor Q1 is limited to a value exceeding a little the Ed/2, and the voltage duty of the power transistor Q1 at the time of turning off can be considerably reduced. Also, since the excess current continues to flow on the transistor Q4 if the state is kept as it is, the Q4 is also turned off similarly.

Title: Manufacture of semiconductor device
Inventor: KATSUKAWA KIMIAKI
IPC: H01L21/52
Filed: 1983-10-21
Abstract: PURPOSE:To prevent the generation of cracks even during high temperature operation by reduction of thermal strain by a method wherein a pellet is brazed by interposing a Cu-W sintered material thin film having countless through holes between the pellet and a package. CONSTITUTION:The pellet 11 is brazed with a solder 12 after the Cu-W sintered chip 13 having countless through holes is brazed to the pellet-mounting part 14 of a package with a solder 12. This manner enables the alleviation of the thermal strain which the pellet receives because of the interposal of the thin chip 13 of Cu-W sintered material having a coefficient of thermal expansion close to that of the compound semiconductor material constituting the pellet between the pellet and the pellet-mounting part of the package. Further, this thin chip using the material has countless through holes, and heat dissipation via the solder filling these through holes is in a large amount; therefore the increase in the thermal resistance can be kept to the minimum.

IPC: H04M1/658
Filed: 1987-08-07
Abstract: PURPOSE:To improve the probability of establishment of communication with an opposite party by detecting the terminal operation by a called party or the end of talking of the caller so as to inform it to an inquiry terminal equipment or a caller terminal requesting the talking. CONSTITUTION:A terminal set 1 starts the supervision of a communication control signal by a signal control circuit 19 by taking a number registration of a terminal equipment 3 as the opportunity. When a cut-off request signal reaches a signal control circuit 19 from the terminal set 2 by a sequence 10, a microprocessor circuit 17 returns a cut-off acknowledge signal to the terminal set 2 by a sequence 11 by talking it as an opportunity and sends a signal signifying the communication enable notice to the terminal set 3 by a sequence 12. The terminal set 3, based on the discrimination by the user, uses a sequence 13 to transmit the result to the terminal set 1. Since the talking is enabled in this state in the terminal set 1, the microprocessor circuit 17 energizes a ringer circuit 28 to call the called party. When a hook switch circuit 22 is activated, the microprocessor circuit 17 returns the acknowledge signal by a sequence 14 to attain talking between the terminal sets 1 and 3.

Title: Discharge lamp lighting device
Inventor: OKADA TAKASHI
IPC: H05B41/282
Filed: 1993-08-09
Abstract: PURPOSE:To provide a discharge lamp lighting device with no noise by synchronizing a chopping frequency for chopping a DC voltage with the frequency of a tube voltage. CONSTITUTION:A DC voltage Vin is chopped by a chopper circuit 1, converted into an alternate current by a D/A converter 2, and applied to a discharge lamp 3. On the other hand, the tube current frequency detected by a tube current detecting circuit 4 and the chopping frequency set by a chopping frequency setting circuit 6 provided on a chopper control circuit 5 are synchronized. Namely, since the chopping output is stopped when the tube current is reduced, and the chopping output is started when the tube current is increased, the tube current waveform is synchronized with the chopping waveform, and the tube voltage waveform is made constant. Thus, the audible frequency component by the voltage fluctuation based on the non-synchronization of both the waveforms is reduced, and noise is eliminated.

Filed: 1981-12-07
Abstract: PURPOSE:To control the 1st and the 2nd equipments connected by one connection cord in both ways by adding a both-way control circuit in parallel to an interface circuit. CONSTITUTION:When a player 1 is operated from an amplifier side 2, closing a selector switch SW3 in the amplifier 2 inverts the state of a corresponding FF in a switching circuit 6 and a selector circuit 11 is switched to a player position by the inverted output. In this state, closing a start switch SW2 grounds the emitter of a TR2. Consequently, the emitter of the TR3 of an interface circuit 13 is also grounded and the TR3 turns on to ground the lower end of the resistance circuit R1 of the player 1. Therefore, a TR1 in the player 1 turns on and the player 1 starts. When the amplifier side 2 is operated from the player side 1, closing the start switch SW1 turns on the TR1 and the player 1 starts. At this time, the amplifier side 2 is switched by the selector circuit 11 through a both-way control circuit 14.
