Furthermore, the series circuit comprising a resistor Rc and a capacitor C is connected between the emitter of the Q2 and a DC power supply Vcc. An output signal v0 is expressed in equation I , where ie1, IE1 are the AC and DC component of the emitter current of the Q3 and ie2 and IE2 are the AC and DC component of the emitter current of the Q3. Thus, with the relation of ie1/IE1=ie2/IE2, the distortion component is cancelled. Then the value of the resistor Rc of the series circuit comprising the resistor Rc and the capacitor C has only to be set as ie1/IE1=ie2/IE2.

Title: Dampproofing material for organic dielectric and its manufacture
Inventor: JIIKUFURIITO BIRUKURE
IPC: H01L23/29
Filed: 1990-01-30
Abstract: PURPOSE: To obtain a preferable adhesive moisture-proof material which can hermetically cover an organic dielectric in an integrated circuit by using a thin film made of amorphous hydrogen contained carbon (a-C:H). CONSTITUTION: A thin film made of amorphous hydrogen contained carbon (a-C:H) is used as a moisture-proof material for an organic dielectric in an integrated circuit. It is advantageous that the moisture-proof material using the a-C:H thin film having the thickness of about 0.05 to 3μm does not have a pin hole by its relatively high density (up to 18g.<-3> ) when the thickness is only 0.2μm or less and does not include any particle boundary and similar particle unevenness because of the amorphous structure. Further, since no crack occurs, a metal peak cannot invade a dielectric layer when an alminium conductive path is arranged. Consequently, the preferable adhesive moisture-proof material which can hermetically cover an organic dielectric in an integrated circuit can be obtained.

Title: Message generating communication device
Inventor: JIYON AARU AGAASU
IPC: H04J3/16
Filed: 1990-01-30
Abstract: PURPOSE: To shorten the processing time of a system required for interpreting a message and to improve the processing efficiency of the system by generating a preamble indicating the presence of a message in a prescribed format for each message transmitted by means of a node. CONSTITUTION: In the partial blocks of transmission-side nodes, messages are generated in the format shown in the figure and the messages are serially transmitted through a data bus 26. When the messages are transmitted, a microprocessor 20 generates a direction bit 10, identification code pattern 11, and the message length 12 of a path 22 which are transmitted through a path 21A. Since the preamble indicating the presence of a message is generated in a prescribed format to each message transmitted from the nodes in such a way, the time required for discriminating the destination of each message can be shortened and the processing efficiency of a communication network system can be improved.

Title: Laser device for observing electronic part
Inventor: SAKAGUCHI HIROYUKI
IPC: G01R31/26
Filed: 1991-02-14
Abstract: PURPOSE:To eliminate a defective measurement caused by dispersion in reflective directions of a laser beam, which has been reflected from a declined lead, by arranging a plurality of laser receiving parts around a laser emitting part. CONSTITUTION:While a moving head 1 picks up an electronic part P through suction and carries the part to a board, the moving head 1 comes above a laser device 3 so as to put a lead L just above a light emitting part 6. A laser beam emitted from the emitting part 6 is reflected to a lead L1. Since the lead L1 is located with a tilt angle alpha, the laser beam provides a large quantity of light to a receiver 8a, but a small quantity of light to another receiver 8c. Consequently, a positional shift or floating of the lead L1 is calculated from a mean value of a total light quantity received at the receiving parts 8a and 8c. When reflected light is received by one of the receiving parts 8a-8d, the lead L1 is considered to be found out. Furthermore, the laser device 3 is shifted to the left, and then a laser beam is emitted from the emitting part 6 to measure a lead L2.
