IPC: H01L21/56
Filed: 1995-04-20
Abstract: PURPOSE: To provide a highly reliable semiconductor device which does not require a large area for resin sealing but requires a less amount of sealing resin and assures accurate connection of bonding wire with a circuit substrate and also well balanced sealing with the sealing resin. CONSTITUTION: A semiconductor element 2 is mounted on a circuit substrate 1 and a bonding wire 3 is fixed on the circuit substrate 1 using wire fixing resin 4 having higher bonding strength to the connecting part of the bonding wire 3 connecting the circuit substrate 1 and semiconductor element 2 on the circuit substrate 1. Meanwhile, the resin sealing is performed by selectively using the sealing resin 5 having reduced stress to have the excellent sealing characteristic at the internal side of the wire fixing resin 4 at the surface of semiconductor element 2. Thereby, protection of the connecting part of the bonding wire 3 is enhanced to prevent generation of warpage or deformation of semiconductor element 2 due to resin sealing.

Title: Method of transmitting measured value in fire alarm unit and device for executing same method
Inventor: PEETAA MIYURAA
IPC: G08B26/00
Filed: 1981-06-22
Abstract: In a fire alarm system individual fire alarms are connected in series by reporting lines with a central signal station. In order to be able to connect a greater number of fire alarms with the individual reporting or signaling lines and/or in order to be able to dispatch an increased amount of current through the reporting lines, the reporting or signaling lines from the last fire alarm of a line are returned back to the central signal station in the form of a ring circuit or loop. Upon the absence of signals at a reporting line an interrogation device is reversed, so that there can be ensured that in the event of a line disturbance or breakdown of a fire alarm the remainder of the fire alarms still can be utilized for giving a signal. The individual fire alarms are structured such that during assembly the inputs and outputs can be mutually interchanged.

Title: Head lamp provided with polarizing plate
Inventor: ADACHI KIYOSHI
IPC: B60J1/02
Filed: 1985-05-04
Abstract: PURPOSE:To make possible to run a vehicle always with the use of high beam lamps to obtain a wide field of view and to avoid dazzling the drive in a car running in the opposite direction to reduce accidents in the nighttime, by incorporating a polarizer in a high beam bulb along in each head lamp, and by incorporating an analizer in the front shield pane. CONSTITUTION:A polarizer is incorporated in a high beam bulb alone in a head lamp at an angle shown in the drawing, and an analyzer is incorporated in the front shield pane. Therefore, the driver may be prevented from being dazzled by a high beam from a car running in the opposite direction. Since no polarizer is incorporated in a low beam bulb, it is possible to confirm a low beam alone as usual. Further, the car may run always with high beams and therefore, it is possible to ensure a wide field of view, avoiding dazzling the driver in a car running in the opposite direction. Therefore, the number of accidents which is relatively large in the night time can be reduced.

Title: Discharge quantity control device for viscous fluid pump
Inventor: OMURA TAKAYOSHI
IPC: F04B15/02
Filed: 1990-04-11
Abstract: PURPOSE:To keep the quantity of discharge constant regardless of fluctuation in oil temperature and loading by sending commans to an electromagnetic proportion pressure reducing valve in such a way that there exists on difference between the number of pulses and a target number of pulses during the time until pistons reach each end of strokes. CONSTITUTION:An electromagnetic proportion pressure reducing valve 19 sets up the tilt angle of an oil pump 14 which supplies pressure oil to main cylinders 1 and 2 actuating a viscous fluid pump. A CPU 22 generates pulses by means of a timer contained, in order to compare the number of pulses produced during the time until pistons 6 and 7 reach each end of strokes with a target number of pulses, and it applies commanding voltage to the amplifier 20 of the electromagnetic proportion pressure reducing valve in such a way that the number of pulses produced agrees with the target number of pulses. By this constitution, the quantity of discharge out of the oil pump 14 is adjusted so that the discharge quantity of viscous fluid is thereby controlled. Accordingly when the actual discharge quantity is made to agree with a set discharge quantity, the discharge quantity can thereby be made constant regardless of fluctuation in oil temperature and loading.

Title: Packet retransmission control system
Inventor: ETSUNO MASAYUKI
Filed: 1988-04-21
Abstract: PURPOSE:To shorten the data holding time of a packet retransmitting buffer by making packet retransmission control possible between a transmitting exchange station and a receiving exchange station as well. CONSTITUTION:If two data packets, for instance, for which an answer from a data receiving terminal 4 is not yet confirmed exist among the data packets transmitted from the receiving exchange station 3 to the data receiving terminal 4, the receiving exchange station 3 transmits a receiving exchange station confirming answer packet 16 whose confirming order number is 2 toward the transmitting exchange station 2. The transmitting exchange station 2 stops a retransmitting timing monitor 6, and releases the copy of a transmission data packets 5 and 10 held in the packet retransmitting buffer 7, and clears it. Thus, the data holding time of the packet retransmitting buffer 7 is extremely shortened compared with the past.
