Patent JP-H02280360-A (JP)
Title: Semiconductor package
Inventor: ONO YUKIMITSU
IPC: H01L23/28
Filed: 1989-04-20
Abstract: PURPOSE:To remove the nonconformity based on the chips and gaps of a package by setting the width dimension between both side faces at the upper half of a package narrower than the width dimension between both side faces at the lower half so that the lead hold may not abut on the margin of the semiconductor package. CONSTITUTION:In mold resin 5, the width dimension X1 between both side faces at the upper half 5 positioned on the side upper than the projected position of a lead terminal 4 may be narrower than the width direction X2 at the lower half 5b positioned on the lower side, that is, so that they may be X1<X2. And the outside ends of the lead terminals 4, which are projected from both sides of the resin mold 5 being formed this way, are curved by using a die 11 and a punch 12. Hereupon, since the width dimension X1 of the upper half is made narrower than the width dimension X2 of the lower half 5b, the lead holder 13 never abuts on the margin 5a of the upper half 5a of the resin 5 installed in the die 11, so such trouble, as that this margin 5c chips off, or that the interface between the margin 5c and the lead terminal 4 opens, ceases to occur.

Title: Failure diagnostic device for occupant protecting device
Inventor: NOMOTO KAZUO
IPC: G01R31/28
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To prevent an ignition current from flowing into a squib in diagnosing a failure. SOLUTION: One end of a squib 10 is connected to an ignition power supply V1 via a parallel circuit between an FET 2 and a resistance 6 and the other end of the squib 10 is grounded via the parallel circuit between an FET 12 and a resistance 16. The resistances 6, 16 have such resistance values becoming to a degree that the current flowing, when either one of the FET 2 or the FET 12 is turned on, does not ignite the squib 10. The FETs 2, 12 are constituted of parallel circuits between drive FETs 22, 122 and high resistance check FETs 21, 121 respectively and a bias voltage is applied to respective gates by turning-off of FETs 5, 15.  In diagnosing a failure, when a wire L1 or a wire L2 is instantly or stationarily short-circuited to a power supply line or an earth respectively, the flowing current is restricted by the check FETs 21, 121 so that the ignition current is prevented from flowing therein and prevent the starting of the air bag device.

Title: Test head with dc measuring function for ic tester
Inventor: SAITOU YOSHIHIRO
IPC: G01R31/26
Filed: 1983-06-10
Abstract: PURPOSE:To complete upto a DC test for a relative short time by adding a DC parametric testing circuit to a test head of an IC tester to perform a DC parametric testing as intact with a logic IC tester. CONSTITUTION:When a DC measuring function is added to a driver and a comparator, a higher speed of the drive and the comparator are not possible and hence, a hybrid IC-converted and miniaturized DC measuring section 3 as discrete unit is carried on a pin electronics. When the pin electronics is used as intrinsic high-speed driver and comparator, a switching relays 5 and 6 are connected to the position (a) to turn OFF an opening/closing relay 7. When the pin electronics is used as DC measuring device, switching relays 5 and 6, are connected to the position (b) to turn ON the opening/closing relay 7. With such an arrangement, the time required for an IC test including a DC parametric test can be reduced significantly.

Title: Joint connector
Inventor: FURUYA MITSUGI
IPC: H01R31/08
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To prevent contact between short-circuit members and to compatibly secure a degree of freedom in setting a short-circuit pattern. SOLUTION: A terminal 20 can be positioned selectively in a plurality of waiting positions, and the position of each receiving groove 21 can be varied in a direction in which it crosses short-circuit plates 25. Since the short-circuit plates 25 fitted into the receiving grooves 21 in different positions are spaced apart in their crossing direction, the plurality of short-circuit plates 25 do not make contact with one another as they would if they are arranged in a horizontal line. Moreover, since there is no need to provide a partition wall such that the mounting area of the short-circuit plates 25 is divided in order to prevent contact, the short-circuit plates 25 of any lengths can be mounted in any positions.

Title: Cpu operation monitor system
Inventor: TAKADA TOKUJI
IPC: G06F11/30
Filed: 1989-04-21
Abstract: PURPOSE:To prevent erroneous output of a signal by comparing address information on an address bus and data information on a data bus with a reference and outputting a restart signal at the time of coincidence between them. CONSTITUTION:An address and data as the reference value are set to an address/data setting means 1. Each time an address and data are outputted to an address bus 101 or a data bus 102 from a CPU 3, they are compared with the reference value by a comparing circuit 2. When this comparison results in coincidence, the CPU 3 is judged to be normally operated and a watchdog timer WDT 7 is reset. If the WDT 7 is not reset within a set time, the operation of the CPU 3 is judged to be abnormal, and an alarm signal is outputted to a signal line 104, and the CPU 3 is reset. Thus, the control is returned to the start of a program and erroneous output of the restart signal of the WDT 7 is prevented.

Title: Hot water-water mixing device
Inventor: YONEKUBO HIROAKI
IPC: G05D23/00
Filed: 1986-05-06
Abstract: PURPOSE:To reduce the transient temperature fluctuation together with reduction of the driving force by controlling the mixing ratio of a mixing valve with control of driving means done by a controller so that the mixed hot water is obtained at a level of temperature set by a temperature setting unit for mixed hot water and at the same time keeping the fixed flow rates of both hot water and water via the fixed flow rate valves set at the hot water and water sides. CONSTITUTION:A setting unit 32 sets the desired temperature and flow rate of the mixed hot water and indicates the start of supply of the hot water. Then both a hot water-side motor 24 and a water-side motor 25 are actuated by a command of a controller 33. Thus a hot water-side valve 19 and a water-side valve 20 open each path. The flow rates of both hot water and water sides are roughly decided by a hot water-side constant flow valve 17 and a water-side constant flow valve 18. Furthermore the temperature of the mixed hot water detected by a thermistor 28 is compared with that set by the setting unit 32 by the controller 33. Then motors 24 and 25 are controlled to eliminate the deviation between said both temperatures. Thus the mixing ratio is finely controlled. In the same way, the mixing flow rate detected by a flow rate sensor 29 is compared with the value set by the unit 32 via the controller 33 for fine control of the mixing flow rate.
