Title: Package for semiconductor device
Inventor: YAMAGUCHI HIROYUKI
IPC: H01L23/31
Filed: 1984-05-22
Abstract: PURPOSE:To enable correct alignment to be performed while eliminating the need of sealing jigs, by utilizing a cap provided with holes so that external leads are inserted through the holes and by setting the cap with the external leads inserted through the holes. CONSTITUTION:A semiconductor element 12 is carried and fixed on the semiconductor element carrying section in a ceramic substrate 1. The electrodes of the element 12 are connected to the electrodes of inner leads of the substrate 1 with metallic small-gauge wires 13. Each external lead 6 brazed to the substrate 1 is inserted through a through-hole 8 provided in a cap 7 and the cap 7 is set and sealed by melting sealing glass 9. Since the roots of the external leads are caught by the sealing glass, the strength of fixing the leads is improved. Further, the material cost can be reduced since Au-Sn or the like is not used for brazing.

Title: Fuel feed stop device for internal-combustion engine
Inventor: OOKUBO AKIRA
IPC: F02M3/045
Filed: 1983-06-09
Abstract: PURPOSE:To stop a spout of fuel from a main nozzle as well as to prevent the occurrence of any deterioration and useless consumption in a catalyzer due to an excessive reaction to the catalyzer of an uncombustive air-fuel mixture, by making suction pressure in a Venturi part and pressure inside a float chamber into being almost equal in time of engine stoppage. CONSTITUTION:In time of engine stoppage, when a key SW21 is opened, air inside a float chamber 12 is drawn by suction to the downstream side of a throttle valve 14 from a port 12a via each of pipes 17 and 18 so that a fixed quantity of suction pressure acts thereon. On the other hand, pressure in a Venturi part 11a comes into a fixed quantity of suction pressure because the air drawn by suction to the downstream side of the throttle valve 14 likewise from the lower end opening of a piston 13 via a chamber 13a and each of pipes 19 and 18. Since the pressure inside the float chamber and the suction pressure in the Venturi part become almost equal, fuel injection out of a main nozzle is stopped. In time of ordinary driving of the engine, atmospheric pressure in a pipe 24 is led into the float chamber by upward motion of a solenoid valve 20b, closing the pipe 19, thus ordinary operation takes place.

Title: Still picture device
Inventor: YOKOTA TETSUPEI
IPC: H04N5/91
Filed: 1982-06-16
Abstract: PURPOSE:To obtain a still picture having no blurring with a single button operation while seeing a television screen, by transferring a data to other recording media from a frame memory if the still operation is not released within a fixed time after the still operation is not released within a fixed time after the still operation ends. CONSTITUTION:If a switch 1 is switched to a contact (b) side, the output side of an FF circuit 2 changes to the low, and the output side of an NOR circuit 3 changes to the high. Therefore, the output side of an FF4 changes to the low. At this moment, the output of an AND circuit 5 becomes low level, and the low level is transmitted to an output terminal Q of an FF6 synchronizing with a frame pulse applied for a terminal 7 so that the gate of the circuit 9 is closed to stop the supply of a writing pulse out of a terminal 10 to a frame memory. If it is within a fixed time after entering this state, the said operation is repeated whenever the switch 1 is pushed. As a result, if the operation of still/release is repeated while pushing the switch 1 within the fixed time, and if the switching operation is stopped when a required still picture is obtained, an operation mode starts to transfer the data in the frame memory to other recording media.

Title: Idling-up control method of engine and device thereof
Inventor: ONODERA TAKAO
IPC: F02D29/02
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To suppress large fluctuation of engine speed so as to correspond to change of all loads by increasing an injection rate of fuel when engine speed is lower than idling rotational speed, and stopping the injection rate to increase when idling upper limit rotational speed is larger than idling lower limit rotational speed. SOLUTION: Fluctuation of a load on idling operation is detected by a signal detected by engine speed detecting means 41, and a rate of fuel injected to an engine 1 is increased/decreased so as to set engine speed to be between idling lower/upper limit rotational speed A, B. In this time, the idling lower limit rotational speed A is set smaller than the idling upper limit rotational speed B. Those lower/upper limits are set, and thereby, the lowest lower limit rotational speed A is ensured when a load is small, idling is carried out, stop of the engine 1 on idling is prevented, and also a fuel consumption rate is suppressed to the lowest limit. When the load is large, it can correspond to the load with rotational speed between the lower/upper limits, and idling is carried out having a margin in load fluctuation.

Filed: 1988-04-28
Abstract: PURPOSE:To easily grasp which bus has arrived and which bus has not arrived by displaying the arrival and nonarrival of the bus on a regular route according to each regular route bus arrivals schedule time displayed on a arrival schedule time display means. CONSTITUTION:A diagram display device 15 of a bus stop is equipped with a reception antenna 16 to receive an arriving signal 14, connected to to a signal reception part 17, and here, the arriving signal 14 is detected. The output of the arriving signal 14 is set at a relatively small value related to the sensitivity of the signal reception part 17, and when the regular route bus arrives at a distance shorter than the interval between the bus stops, the signal is detected. The signal reception part 17 receives the arriving signal 14, senses the signal level at two stages, and in the condition in which the signal level is at the relatively small value, bus approaching information is supplied to a display control part 19 as arriving information 18 together with the schedule time. In the condition in which the signal level is at the relatively large value, the bus arriving information is supplied to the display control part 19. Thus, since the arrival or nonarrival of the bus on the regular route is discriminated, a use can easily select the bus, etc.
