Title: Communication device and remote control device
Inventor: YAMASHITA SHUJI
IPC: E05B49/00
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to surely receive oscillating frequency with a transmitter even if oscillating frequency of the transmitter making use of an LC oscillation circuit is unstable. SOLUTION: A transmission control section 2 reads out an ID code from an ID code storage device 3, and it is transmitted to a VCO control circuit 5. Output voltage of the VCO control circuit 5 is increased from VL to VH in an H level part of the ID code, and it reaches VL in an L level of the ID code. Since a VCO 6 generates frequency varied with output voltage of the VCO control circuit 5, carrier frequency is varied in the H level part of the ID code. When sweep range of the carrier frequency is swept across a received frequency band, even if the carrier frequency of the transmitter is varied, the carrier frequency swept by the transmitter 1 is received by a receiver as long as the carrier frequency is overlapped with the received frequency band. Then, transmission data is shaped by a waveform shaping circuit to reload.

IPC: G11B15/02
Filed: 1984-08-13
Abstract: PURPOSE:To simplify external circuits by inputting a reproducing output of two magnetic recording and reproducing heads to a signal detection circuit after being mixed, inputting an output of the signal detection circuit to a microcomputer for mechanism control and allowing a microcomputer to discriminate the relation between an operated mechanism and the signal detection circuit. CONSTITUTION:Outputs reproduced by recording/reproducing heads 1, 2 are amplified by reproducing preamplifiers 3, 4, the result is inputted to a low-pass filter 5 via resistors 35, 36. When either a reproducing output of the 1st recording/reproducing head or that of the 2nd recording/reproducing head exists in an input port 25, an output of an input scan output port 23 is inputted, an interblock is reproduced for both and after a prescribed time is elapsed, no input exists at the input port 25. Thus, it is not required to provide two circuits after the low-pass filter. When a program search function is given to plural mechanisms in addition to the 1st and 2nd mechanisms, it is executed by using resistors only and the circuit constitution is simplified remarkably.

Title: Automobile heating device
Inventor: KUBOTSUKA TAKAO
IPC: F01P7/16
Filed: 1984-08-13
Abstract: PURPOSE:To maintain the temperature of a passenger's compartment substantially constant, by directly or indirectly detecting the temperature abnormal condition of blow-out air from a heater core to control the discharge amount of coolant from a heater pump. CONSTITUTION:When a heater switch 34 is turned on, a heater pump 18 is operated to introduce a part of coolant from the cylinder side 6 of a cooling jacket 2 through a heater coolant introduction passage 20 into a heater core 17 where it heats air for heating the passenger's compartment which is blown by a blower 23 and it lowers its temperature due to heat-exchange. Further, the coolant whose temperature has been lowered is introduced into the cooling jacket 2 through a coolant return passage 21 by the heater pump 18. The air whose temprature is raised up due to heat-exchange in the heater core 17, is blown out into the passenger's compartment from a heater blow-out port 24 for heating. At this time, the temperature of air is monitored by a temperature sensor 27 and is delivered to a controller 28. When the temperature of blow-out air exceeds a set value, a stepping motor 29 is driven to lower the rotational speed of the pump 18 so that the amount of heat-radiation from the heater core 17 is reduced.

Title: Optical element coupling module
Inventor: SHIKADA MINORU
IPC: H01L31/02
Filed: 1983-09-12
Abstract: PURPOSE:To manufacture an optical element coupling module which has high couping efficiency at high yield and in a short time by moving a fixture base for an optical fiber, etc., and adjusting the positions of both optical fibers and coupling them optically. CONSTITUTION:The incidence terminal 12 of an optical fiber 6 is put close to a semiconductor laser element 1 previously and soldered fixedly to the optical fiber holding part 9 of the fixture 7. When an external force is applied to the holding part 9, the holding part 9 moves around a thin plastic deforming part 11 as a fulcrum, so the position of the incidence terminal 12 of the optical fiber 6 is adjusted by varying the fitting attitude of the holding part 9 so that the output light of the element 1 couples with the optical fiber 6 efficiently. The plastic deforming part 11 made of copper is easy to deform plastically, so the external force is removed after the incidence terminal 12 is set at the best coupling position, and then the shape of the deforming part 11 is held as it is, holding the best coupling state as it is. The deforming part 11 is closest to the incidence terminal 12, so the motion is reduced to a fraction of several of the motion of the holding part 9 to make a fine coupling position adjustment.

Title: Structure of connecting terminal of contact
Inventor: MORIKAWA MORIKAZU
IPC: H01R4/02
Filed: 1995-06-12
Abstract: PURPOSE: To improve the strength of soldering by soldering on as wide an area as possible and drawing solder into parts to be connected by surface tension. CONSTITUTION: A terminal part 83 of a contact 82 has a groove of larger diameter than the diameter of a lead wire and a small hole 84 bored in the bottom of the groove. When solder 19 flows between the terminal part 83 and the lead wire by surfaced tension, air between the terminal part 83 and the lead wire is removed because of the above described structure of the terminal part 83, whereby air layer does not remain between the terminal part 83 and the lead wire and the solder 19 flows into the small hole 84. Since the small hole 84 is small, the solder 19 does not drop. It is judged whether the solder 19 surely enters gaps or not by ensuring from the bottom side that the solder 19 flows also into the small hole 84.

Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to judge whether or not a circuit is passive fast and to specify what causes the circuit not to be passive before a circuit simulator analyzes circuit characteristics. SOLUTION: Circuit information on an electronic circuit to be simulated is inputted (S1) and it is judged that a linear element circuit included in the circuit is passive, i.e., whether the circuit is a circuit which always consumes electric power. In this process, an inductance matrix of the circuit is generated (S2) and it is checked whether or not the inductance matrix is plus by finding the value of its small matrix expression (S5); when the diagonal term of the matrix is plus, it is judged that the circuit is passive (S6 and S8) and when not, it is judged that the circuit is not passive (S5 and S9). In this case, additional information showing what causes the circuit not to be passive is outputted from the information of the said small matrix expression (S10).

IPC: G01B21/08
Filed: 1987-07-06
Abstract: PURPOSE:To achieve a rationalization of measuring work and a higher accuracy, by lifting and moving a plate body to be measured by vacuum suction while a measuring device is set at a fixed position. CONSTITUTION:A frame 19 of a suction pad 20 is adjusted to match a plate body 13 to be measured and the plate body 13 is placed on a controller 23 using a teaching device 24 and a position and a measuring position on a flat plate 11 to be taken off are inputted. As started with a control panel 25, a moving device 15 lowers the suction pad 20 onto the plate body 13 to suck it in vacuum; then, the plate body 13 is lifted and a first plate thickness measuring position is lowered to match the position of a measuring section 14. The measuring section 14 lowers to measure the thickness of the plate body and rises again after the results are recorded on the device 23. Then, a second measuring position is shifted to match the position of the measuring section 14 and a measurement is performed. The results of measurement are displayed on a printer 25. This achieves efficient operation by automatic measurement and a higher accuracy as the measurement is performed at a fixed position, thereby realizing a rationalization and a higher accuracy without damage otherwise caused by the movement by vacuum suction.

Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To make the effective inductance of a metal interconnection connecting an electrode pad on a semiconductor chip to an inner lead on a package zero in order to realize a wire bonding-type high-speed semiconductor device in which a noise and a crosstalk noise due to a simultaneous switching operation are small. SOLUTION: Electrode pads on a semiconductor chip are arranged alternately in the order of electrode pads for a power supply, at least one electrode pad for a signal and electrode pads for a ground. Metal thin wires 4 which connect the electrode pads to internal terminals are formed in such a way that one metal thin wire for the power supply, one metal wire for the ground and a metal thin wire, for the signal, which is sandwiched between the metal thin wire for the power supply and the metal thin wire for the ground form one set, and the metal thin wires are wire-bonded in such a way that they are nearly parallel and that their length is nearly identical. When the metal thin wires as one set are arranged in a width of within 700μm, an effect is large.  When an interconnection for a power supply system and an interconnection for a ground system are put together from the internal terminals up to external terminals so as to reduce the number of external terminals, the compatibility of a wire bonding-type semiconductor device with a conventional semiconductor device can be ensured regarding a mounting property.
