Title: Lead frame for plastic seal type semiconductor device
Inventor: YAMANAKA SEISAKU
IPC: H01L23/50
Filed: 1983-05-30
Abstract: PURPOSE:To obtain a lead frame having a function of high-sealing reliability by joining the lead frame and plastics through SiO2 or Si3N4 layers formed on both surfaces of the inner lead section of the lead frame in a plastic seal type IC. CONSTITUTION:Bond-ability among a sealing resin 12 and lead frames 11 is improved by forming thin layers consisting of SiO2 or Si3N4 coatings 14 on both surfaces of inner lead sections 13 as sealing sections with plastics 12 of the lead frames 11, and the intrusion of moisture into a package from a joining interface is prevented. The SiO2 or Si3N4 layers 14 are used in order to improve bond- ability because these silicon compounds have excellent adhesive properties with epoxy resin as the sealing resin 12 and a Fe-Ni alloy (such as 42 alloy) or a copper alloy employed as the lead frames. Since variance under the state of oxidation of the surfaces of the lead frames due to heating in chip bonding and wire bonding processes is eliminated and the properties of the surface are made constant at all times, a matching with the conditions of sealing is facilitated, and a leakage path is shortened particularly.

Title: Analog voltage reader
Inventor: KURIYAMA SHIGEZO
IPC: H03M1/08
Filed: 1993-04-23
Abstract: PURPOSE:To provide an analog voltage reader formed simply and inexpensively in which the input and the output are isolated. CONSTITUTION:A voltage-pulse train conversion circuit 2 outputs a pulse train whose frequency corresponds to a read object analog voltage. A photocoupler 3 is used to provide isolated pulse trains to a counter 4. The counter 4 counts the number of pulses of the pulse train. A CPU 6 calibrates the count in the counter 4 based on the reference pulse number stored in a memory 5 to obtain a digital value in response to the read object analog voltage. Since the photocoupler is used to isolate the reader, the effect of externally incoming noise is hardly susceptible. Since one photocoupler is enough for one channel, the configuration is simple and inexpensive.

Abstract: PURPOSE:To make it easy for the rider of a vehicle to get into and out of it, by providing a flip-up locking unit which is operated in motive conjunction with the opening and closing of a door so that a tilter bracket in a flip-up position is locked when the door is opened. CONSTITUTION:When a door is opened after a tiltable column 73 is flipped up, a wiring 115 is pulled because of the opening stroke of the door so that a flip- flop locking cam 83 is turned clockwise. As a result, a cam surface 83a is brought into contact with a locking lever 83 and stopped. The tiltable column 73 is thus flipped up and locked. At that time, the excess stroke of the door after the flip-up locking cam 83 has reached the limit to its turning is absorbed by the elongation of a helical spring 116. When the door is closed, the wire 115 is returned so that the flip-up locking cam 83 is turned counterclockwise by the force of a helical torsion spring 84. As a result, the tiltable column 73 is unlocked.
