Title: Group call system
Inventor: MATOI KAZUMASA
IPC: H04W8/20
Filed: 1994-12-06
Abstract: PURPOSE: To eliminate trouble in operation and enable a communication with plural opposite stations by sending call code data including the memory addresses of all stations in one group that a master station store in its memory and data on communication conditions as a group call memory signal, and storing the signal in memories when all the slave stations receive the signal and entering a selective calling operation ready state. CONSTITUTION: A master station call code is inputted to an address 0 of a memory from the keyboard of an operation part 6. Assuming that there are 15 subordinate stations in a group, the call code of a slave station 1 is inputted to an address 1 and similarly, the call code of a slave station to an address F from the keyboard of the operation part 6. When the call codes of all the slave stations are thus inputted, they are read out in order and displayed on a display unit 7 for confirmation. After the all the memories are confirmed, a transmission switch is pressed to send a stand-by signal. Group call memory data, on the other hand, is converted by a DTMF generator 12 into a DTMF signal, which is sent 5 seconds after the stand-by signal.

Title: Heat radiation sheet
Inventor: ISHIGURO SHIGEKI
IPC: H05K7/20
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To provide a heat radiation sheet which excels both in heat conductivity and flame retardant property by including, in the sheet, at least the specified number of fillers which have good heat conductivity and are different in average grain diameter and a viscous layer which is plastically deformed under pressure. SOLUTION: This sheet includes at least two or more types of fillers which also serve for a flame retardant and have a good heat conductivity and are different in average grain diameter. It also includes at least a viscous layer 1 which is plastically deformed under pressure. Since the viscous layer 1 is blended with two or more types of fillers which are different in average grain diameter and have a good heat conductivity, a high blending quantity is achieved by a close-packed filling method, etc., thereby obtaining a radiation sheet having good heat conductivity. Even when a radiator has a large deformation such as a large unevenness, the sheet can be attached airtightly in a large area to both the heating element and a heatsink, since the viscous layer 1 is also plastically deformed and therefore has good heat radiation efficiency.  For the fillers, such materials as to serve as a flame retardant are used. So, the sheet can be easily provided with a flame retardant property, resulting in obtaining a heat radiation sheet which excells both in heat conductivity and a flame retardant property.

Title: Semiconductor integrated circuit
Inventor: SHINJO KEISUKE
IPC: H01L27/04
Filed: 1988-12-27
Abstract: PURPOSE:To improve noise resistance by inserting a circuit for wave shaping at an output signal line from an oscillation circuit located inside. CONSTITUTION:It has a waveform shaping circuit formed by an inner block connected to an output signal wire of an oscillation circuit. That is, the oscillation circuit consists of an oscillator connected to a bonding pad 1, an inverter circuit 3, and a buffer circuit 4. A Schmitt trigger buffer circuit 5 for waveform shaping is connected to the oscillation circuit and the output is connected to internal circuits 15 and 16. Since the Schmitt trigger circuit 5 eliminates noise included in the output of the oscillation circuit, noise is not transmitted to the internal circuits 15 and 16. Thus, other interface circuits can be placed for example at a region 12 near this oscillation circuit and it is not necessary to consider the position of the oscillator especially regarding the 10 pin position of the semiconductor integrated circuit.

Title: Information retrieval device
Inventor: KASHIWAGI KAZUO
IPC: G03B21/11
Filed: 1987-12-26
Abstract: PURPOSE:To perform retrieval in the shortest time corresponding to various films which differ in mark interval by measuring the mark intervals of an information recording medium at the start of retrieval and varying the carrying speed of the information recording medium according to the measured value. CONSTITUTION:When a mark on a film enters a counter 42 through a 1st mark detector 21 at the start of the information retrieval of the information recording medium, its signal is sent to a mark interval measuring circuit 63. When the predetermined signal is inputted to the mark interval measuring circuit 63, respective mark intervals are counted according to speed information from a carrying control circuit 48 and time information on mark detection. The arithmetic means of mark intervals is calculated to obtain a mean mark interval, and the carrying speed is set fast when the mark interval value is relatively long or slow when relatively short according to said mean value. Consequently, each information recording medium can be carried at the maximum speed where the retrieval is possible, so the retrieval time can be shortened by information recording media.
