Title: Formation of bump on semiconductor device
Inventor: ITOU MUTSUSADA
IPC: H01L21/60
Filed: 1993-09-02
Abstract: PURPOSE:To allow formation of good bumps for all devices by coating an underlying material with a photosensitive liquid resist and then laminating a photosensitive dry film resist thereon. CONSTITUTION:An underlying material, i.e., a barrier metal 4, is formed on a semiconductor wafer 1 provided with an Al pad 2 and a passivation film 3. The barrier metal 4 is then spin coated with a photosensitive liquid resist 5 with a thickness corresponding to the height of the bump and then it is heated and temporarily dried until 49-90% of solvent is gasified 6. Subsequently, photosensitive dry film resist 7 having uniform thickness is applied to the temporarily dried fluid resist 5 and laminated by thermocompression such that the surface of the photosensitive liquid resist 5 is planarized uniformly. Crowns existing on the periphery of the semiconductor wafer 1 are pushed into holes 8 along with excess resist through the thermocompression thus bringing about uniform total thickness over the entire surface of resist 5.

Title: Video signal processor
Inventor: KUJIME SADAO
IPC: H04N5/10
Filed: 1990-09-11
Abstract: PURPOSE:To write one frame without missing the half of the field even in the case of a non-standard signal by detecting a state change from an odd- number field to an even-number field (or from the even number to the odd number) and synchronizing the output of a synchronizing separator circuit by a pulse generation circuit. CONSTITUTION:The pulse generation circuit equipped with a function to divide the frequency of a vertical synchronizing signal into two frequencies is further added to a conventional field discrimination circuit. In this case, the pulse generation circuit is formed by a D flip-flop 18 and two gate elements 19a and 19b. Then, the state change from the odd-number field to the even-number field (or from the even number to the odd number) is detected, and the output of a synchronizing separator circuit 11 is synchronized by the pulse generation circuit. Thus, even in the case of the non-standard signal fixing vertical and horizontal synchronizing phases, one frame can be written without missing the half of the field.

Title: Cellular cordless system
Inventor: UMETSU KAZUHIRO
IPC: H04W56/00
Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To allow a slave set to receive stably the service of a base station and a master station by matching a reference frequency of the master set with a reference frequency via the slave set even when the master set is resident in a dead band of the cellular base station. SOLUTION: A control mode designation section 47 of a slave set receives a transmission signal of a cellular base station at initializing and designates a mode of adjusting a reference frequency to a control voltage calculation section 44 and then the oscillated frequency of a reference oscillator 45 is adjusted. On the other hand, when the master set cannot receive a transmission signal from the base station at initializing, a reception signal discrimination section 39 discriminates it and a control mode designation section 37 receives a transmission signal from the slave set to designate the mode of adjusting the reference frequency to a control voltage calculation section 34 and then a reference oscillator 35 is adjusted.  Thus, even when the master set is resident in a dead band of the base station, the slave set surely receives the service by the master station and the base station.

Title: Select return mechanism for transmission
Inventor: TOYODA HIDEO
IPC: F16H59/04
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To exert a proper select return function with a relatively simple structure. SOLUTION: For a selecting action, the extension sections of spring members 24, 25 are displaced at the lower section, reaction is applied upward from the extension sections, i.e., select return reaction is transferred from the spring members 24, 25 to a neutral position from a 5-R select position. Since the tilt angle β of the extension section of the spring members 24, 25 on the 5-R select position side to a vertical rod side is larger than the tilt angle α of the spring member 24 on a 1-2 select position side, the load state of the spring members 24, 25 on the 5-R select position side to the vertical rod is larger than the load state of the spring members 24, 25 on the 1-2 select position side, and the generated select return reaction of the springs 24, 25 on the 5-R select position side is made larger than that on the 1-2 select position side.

Title: Rush current preventing circuit of dc stabilized power source
Inventor: KOBAYASHI TOSHIO
IPC: G05F1/10
Filed: 1984-11-16
Abstract: PURPOSE:To obtain small-sized inexpensive power source by forming an auxiliary power source by the output of a rush current preventing resistor. CONSTITUTION:A commercial power source V0 is rectified by a rectifier 9 to a DC power through the primary smoothing capacitor 10 and a DC/DC converter to obtain an output voltage V2. When the commercial power source is turned ON, if an auxiliary voltage V1 stepped down and rectified by a commercial transformer 19 is generated, the converter operates to feedback the voltage of the winding 13 of a high frequency transformer 12 to conduct a switching element 4. Thus, a rush current preventing resistor 5 is shortcircuited to perform a normal operation. in this case, the voltage V1 is obtained from the output V3 of a rush current preventing resistor 5. Thus, since the output V3 of the resistor 5 is delayed by the time constant of the capacitor 10 and the resistor 5, the power V1 becomes a delay waveform to prevent the rush current when the converter is operated.

Title: Manufacture of multiple parallel lines
Inventor: YAMAGUCHI SHIGEO
IPC: H01B13/00
Filed: 1990-09-11
Abstract: PURPOSE:To manufacture multiple parallel lines with good accuracy and at low cost without providing a winding groove on a mandrel by winding a guide wire around the mandrel in such a way that a base wire is preceded by the guide wire, and by winding the base wire around the groove between each guide wire. CONSTITUTION:A guide wire 11 and a base wire 12 are solidly wound at a certain pitch on a mandrel 10 of certain diameter, in such a way that at least a winding angle theta of 60 deg.C is formed between the guide wire 11 and the base wire 12. The base wire 12 is wound around the groove between the guide wire 11 precedently wound and an adjacent guide wire 11 which is already wound. Each base wire 12 is then bonded and fixed to one another, and a group of base wire 12 bonded and fixed, is cut in the longitudinal direction of the mandrel 10, so as to peel off the group of base wire 12 from the guide wire 11. A mandrel provided with a winding groove is not needed thereby, and multiple parallel lines of fine arrangement wire pitch can thus be manufactured with high accuracy and at a low cost.

IPC: C09D5/23
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To prevent a filler from dropping from a base film surface in a coating process, smoothening process or hardening process of a magnetic layer and to hardly cause dropout by applying a coating liquid for a back coating layer before applying a coating liquid for a magnetic layer on a nonmagnetic base body. SOLUTION: Before a coating liquid (B) for a magnetic layer is applied, a coating liquid (A) for a back coating layer is preliminarily applied on the opposite surface of a nonmagnetic supporting body to the surface where the magnetic layer is to be formed. By this method, contact between the surface of the nonmagnetic base and guide rolls can be prevented in the coating process of the coating liquid (B) to form a magnetic layer or in the smoothening treatment in a calendering machine can be prevented, or direct contact between the surface of the nonmagnetic base body and the magnetic layer surface can be prevented in a hardening process. Therefore, such problems are prevented that the nonmagnetic base body is broken by external stress such as friction and drops from the medium and that fillers in the nonmagnetic base body drop are released.

Title: Diagnostic system of logical circuit
Inventor: SATOU YOSHIO
IPC: G06F11/26
Filed: 1983-12-23
Abstract: PURPOSE:To improve the efficiency of trouble detection by selecting an optimum loop cut point for a circuit including a loop circuit, and inserting an indeterminate value. CONSTITUTION:The efficiency of trouble detection is highest when the number of trace passing pins from a trace origin to the loop cut point is maximum. When tracing starts at input pins 3.16 and 3.17 of an OR gate 3.8 as the trace origin, two circuits (a) and (b) are formed. When the tracing starts at the trace origin 3.19, (a) includes 3.19, 3.18, 3.16, 3.13, 3.12, 3.10, and 3.9 and (b) includes 3.19, 3.18, 3.16, 3.13, and 3.12. Therefore, when the number of trace passing pins is compared, 7:5 is obtained. Consequently, the number of trace passing pins of the circuit (a) from the trace origin to the loop cut point is larger than that of the circuit (b). Therefore, the circuit (a) is a circuit including the optimum loop cut point. An indeterminate value is inserted into this loop cut point to improve the efficiency of trouble detection.

Filed: 1983-12-23
Abstract: PURPOSE:To make a size constant irrespective of brightness of a picture by changing the magnitude of vertical deflection current by voltage corresponding to the beam current of a cathode ray tube. CONSTITUTION:When the brightness of a picture increases and a beam current increases, voltage drop of a resistor 11 becomes larger. This voltage is led through the buffer of a Tr22 and utilized. The voltage obtained in the emitter of the Tr22 is regulated by resistors 20 and 19 and fed to an N-FET18 gate. Thus, when the brightness of picture changes, the gate voltage of the FET18 changes and the resistance between drain sources changes. At it is connected to the feedback path of an IC for vertical oscillation pre-amplification 16 through a condenser 17, saw tooth voltage for feedback AC changes with the brightness of the picture. For instance, when a picture becomes brighter, feedback saw tooth wave components becomes larger, and the vertical deflection current becomes smaller.
