An emitter area ratio of TRs Tr7 and Tr1 and TRs Tr8 and Tr2 is set to 1:N (N is a positive real number), and the value of a resistance R6 connected to the emitter of a TR Tr4 is so set that a collector current I3C of the first driving TR Tr3 is larger than a collector current I4C of the TR Tr4 in the first by-pass means. The value of a resistance R7 is set in the same manner. Thus, the idling current is reduced without reducing the drive capability for a load.

Title: Driving device for liquid crystal display element
Inventor: SU SHOKU SHIM
IPC: G09G3/36
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To enable one DAC to handle many channels and to make the driving device small in size by preparing a counter part and a DAC part, and sampling and holding the voltage level of the DAC part output by a sample holding circuit according to a counter value outputted by a comparator. SOLUTION: The comparator 43 compares the output of the counter part 41 with inputted data and outputs it when they match each other. The output signal of this comparator is a digital signal, which has a level of almost 0 to 5V. The level of the output signal outputted from the DAC part 42, on the other hand, is approximately 0 to 10V, so the levels are mutually different. To solve this problem point, a one-bit level shift 44 is prepared at the output end of the comparator 43. When the comparator 43 generates the output, the sample holding circuit 45 samples and holds the current level of the DAC part 42, i.e., the voltage level outputted with the count value of the counter 41 with the signal from the level shift 44.

Title: Antenna measuring method
Inventor: TSUTSUMI TAKASHI
IPC: H01Q3/26
Filed: 1983-12-06
Abstract: PURPOSE:To shorten the measuring time of a digital phase shifter by obtaining a ratio (r) of maximum to minimum of amplitude variance and a phase variation DELTA0 for a maximum amplitude from a measured value of specific bits by calculation processings. CONSTITUTION:When a phase variation is denoted as DELTA, a received amplitude variance ¦E1¦<2>/E0<2> is expressed with A+Bcos(DELTA+DELTA0). Therefore, the phase variation DELTA is measured at intervals of a value corresponding to three bits, namely, 45 deg., and measured values are used to calculate values A, B, and DELTA0 by, for example, the minimum squaring method. Thus, the ratio (r) of maximum to minimum of amplitude variance is obtained in accordance with r=[(A+B)/(A- B)]<0.5>. The measuring time is shortened to ZN/Z<3> when an N-bit phase shifter is used.

Title: Switching power supply unit
Inventor: EGURI MOTOHARU
IPC: H02M3/28
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To reduce the size of a switching power supply unit by suppressing the generation of its through current, in the case of its transience. SOLUTION: In the case of the transience of a switching power supply unit, a large current ID2 for charging a capacitor 5 flows in the forward direction of a built-in diode 8, when turning off a MOSFET 2. A through-current suppressing circuit 33 interrupts the feeding of a drive voltage VG1 to the MOSFET 2, until the current ID2 becomes zero. That is, in a state of the forward current flowing in the self-contained diode 8, the MOSFET 2 is not turned on. Therefore, a large throughcurrent be prevented from flowing in the built-in diode 8, by bringing it into an electrical continuity during its recovery time.

Title: Optical information recording medium
Inventor: HIRANO MASAO
IPC: G11B7/2433
Filed: 1990-08-31
Abstract: PURPOSE:To improve the accuracy of recording and reproducing information by disposing a 1st and 2nd lattice layers which hold a recording layer in-between in such a manner that the positional relations of light transmission regions and light shielding regions are alternated with each other. CONSTITUTION:This recording medium has such structure that the recording layer 1 recorded with information by the presence and absence of double refractive regions 11 is sandwiched by the 1st lattice layer 2 and the 2nd lattice layer 3. The light progressing in the thickness direction by passing the light transmission regions of the 1st lattice layer 2 is shielded by the light shielding regions 22 of the 2nd lattice layer 3 if this light advances rectilinearly with substantially no bending of the course, but if the course direction is changed at a proper angle by the recording layer 11, the light is emitted through the light transmission regions 31 of the 2nd lattice layer 3 to the outside in some cases. Namely, the double refractive regions 11 of the recording layer 1 emits the light passing the light transmission regions 21 of the 1st lattice layer 2 and progressing in the thickness direction to the outside from the light transmission regions 31 of the 2nd lattice layer 3 by properly changing the course direction of a part of this light. The information recorded by the presence or absence of the double refractive regions 11 is read in this way. The exact recording and reproducing are thus possible.

Title: Method for detecting interrupt signal of microcomputer
Inventor: SAITO KAZUHIRO
IPC: G06F11/30
Filed: 1984-11-02
Abstract: PURPOSE:To surely detect interruption whether it is caused by a noise, etc., or produced by a proper interrupt signal, by discriminating the state of an interruption requesting FF at the beginning of the interruption processing. CONSTITUTION:When a signal inpressed upon an interruption input terminal INT becomes '0' due to a noise, '1' is again impressed upon the terminal INT during a waiting time T, since the time T is set in a microcomputer 1 by means of a timer. Therefore, both an output terminal A1 and the input terminal INT become '0' and the fall is detected by a detecting circuit 2. After the fall is detected, an interruption requesting FF 3 is set. Therefore, an interruption requesting signal INTREQ is discriminated as '1' and the signal impressed upon the input terminal INT is discriminated as a noise, and the successive interruption processing program is not executed, but a prescribed instruction is executed and the FF 3 is reset. Furthermore, an interruption permitting FF 9 is set by means of a set instruction and operations are returned to the original program.

Abstract: PURPOSE:To eliminate poor discharge of ink due to a clogging and mixing air at an ink discharge port by providing a closing means in a path for supplying air to the head adapted to perform a recording flying ink drops on an air current to jet an ink in a ink chamber by an air pressure. CONSTITUTION:An ink liquid is discharged to record by a voltage to be applied between an electrode 1 and an ink in an ink discharge port 2 and an air current always flowing out of an air discharge port 3. When no signal voltage is applied, the air pressure due to the air current near the ink discharge port 2 is made equal the pressure of the ink in the ink chamber 4 to stabilize ink meniscum at the discharge port 2 and to meet this requirement, the air current from an air supply source 5 is sent to an air chamber 6 while to an ink reservoir 7. Therefore, when a closing valve 8 is proved in an air supply path between the air supply source 5 and the air chamber 6 and closed, the balance of the pressure breaks and the ink in the ink chamber 4 spurts out of the discharge port 2 to discharge dirts and bubbles. In the recording operation, the closing valve 8 is kept open.
