IPC: H01L23/28
Filed: 1977-09-24
Abstract: PURPOSE:To obtain a high-density circuit package which features a high-density packaging and a high heat radiation property as well as reduced package processes. CONSTITUTION:The following component parts are provided: substrate 1 containing the through-hole; the cooling plate which contains projection part 4 to be inserted into through-hole 2; low-heat resistance material 5 which fills up the gap between substrate 1 and part 4 in the state under which the projection of the cooling plate is inserted; and chip 7 which is attached to substrate 1 with adhesion to material 5. Thus, the semiconductor IC chip is packaged directly to the print substrate, so the package density can be increased. At the same time, the operation speed is increased, and also the heat radiation efficiency is enhanced since the chip and the heat sink are jointed via the through-hole solder. In addition, the package assembling process number can be reduced owing to a simple constitution of just the chip, print substrate and heat sink.

Title: Current limiting unit
Inventor: IMAI KEISUKE
IPC: H01C7/13
Filed: 1988-05-11
Abstract: PURPOSE:To prevent a superconducting material from damaging by interposing an insulator at the intermediate of metals covering the peripheries of a ceramic superconducting material in a cooling tank, leading terminals each having a resistance from the metals of both sides out of the tank, and connecting them by a fuse. CONSTITUTION:The outer periphery of a current limiting wire 10 composed of a ceramic superconducting material 21 is covered with split conductive metal layers 22 divided by an insulator 23. In order to cool the wire 10 with refrigerant 12 made of liquid nitrogen, it is contained inside a cooling tank 11, a heat insulating layer 14 and a heat insulation tank 13, and connected to a line 50 through terminals 15, 16. Terminals 18, 19 having resistances from the split metal layers 22 are led out of the cooling tank, and a fuse 20 is connected therebetween. Thus, when an excess current more than the critical current of the wire 10 flows to shift to a quenching state, it is bypassed by the layers 22, the terminals 18, 19 and the fuse 20 to suppress a current value, thereby preventing the wire 10 from burning.

Title: Frequency synchronizing system for satellite communication
Inventor: WATANABE TATSUO
IPC: H04J3/06
Filed: 1980-08-25
Abstract: PURPOSE:To always secure an establishment of the synchronism to the reference frequency of a satellite and thus increase the efficiency of transmission, by controlling the phase difference between the reference frequency from the satellite and the returned frequency from the self-station by the use of plural PLLs in the TDMA system. CONSTITUTION:At the ground station, the reference frequency fDR sent from a satellite and the signal fDi produced from the signal transmitted from the self- station and returned by the satellite are extracted by the receiver 2 plus the demodulators 3 and 3a. And the phase difference between the both signals is detected by the wave detector 8, and then the output fUi of the VCO 10 is controlled via the loop filter 9 so that the phase difference mentioned above may become zero. At the same time, the frequency conversion 7 is given to the signal fDR through the PLL consisting of the phase detector 8a. the loop filter 9a and the VCO 10a each. Then the phase difference is obtained between the output of conversion and the output fUi of the VCO 10 to control the output of the VCO 10a. As a result, the phenomenon in which the reference frequency of the satellite has a fluctuation at the ground station according to the Doppler effect can be absorbed perfectly at the ground station. Thus the synchronism can always be obtained with the reference frequency of the satellite at the ground station.

Title: Piercer plug for manufacturing seamless steel tube
Inventor: MIYAHARA MITSUO
IPC: B21B25/00
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To improve the service life by specifying the relationship of the maximum outer diameter, the overall length, the maximum inner diameter, and the maximum depth of an inner hole of a rear end opening formed in an axial center part of a piercer plug whose contour is of shell shape to control propagation and piercing of a crack generated in the inner hole to an outer surface of the plug as much as possible. SOLUTION: Based on various kinds of examination on the relationship between the plug shape and the generated stress by the stress analysis using the finite element method, the stress generated in the plug can be reduced if the size of an inner hole is set so as to satisfy the specified conditions, and the frequency of use of the plug from generation of cracks from the inner hole to propagation and piercing to the outer surface of the plug can be increased as many as possible. That means, the inner hole of the piercer plug for manufacturing a seamless tube is determined so that the value (Di/Do)×(h/L) is 0.05-0.35 where Do is the maximum outer diameter of the plug, L is the overall length, Di is the maximum inner diameter of the inner hole, and (h) is the maximum depth of the inner hole.

Filed: 1990-05-02
Abstract: PURPOSE:To make it possible to perform heat dissipation without the necessity of a cooling device or a heat sink by making a die-pad part of a lead frame into a structure to generate the Peltier effect, and by passing electric current in the direction in which a conductive plate bonding an IC chip absorbs heat. CONSTITUTION:An IC chip 1 is bonded on the die-pad part of a lead frame which is connected in a three-layer structure consisting of the upper layer of a conductor plate 2 (composition: Bi2Te2) and the lower layer of a conductor plate 4 (composition: Sb2Te2) with the medium layer of a bulk semiconductor device as an electric conductive heat-insulating material 3. The conductive plate 2 and the lead 5 of a lead frame is wired by a lead wire 6, thus a package 7 is configurated. In the package, the surface of the conductive plate 4 is ex posed with mold resin. Therefore, by passing the electric current to the direction that the conductive plate 2 to be bonded with the IC chip 1 can absorb the heat due to the Peltier effect, the heat generated by the IC chip 1 is absorbed in the conductive plate 2, and is conducted to the conductive plate 4 through the electric conductive heat-insulating material 3, and then the heat is dissipated to the outside from the conductive plate 4. As a result, the lead from itself can absorb the heat generated by the IC chip 1, and dissipate it efficiently.

Title: Semiconductor storage device
Inventor: SAKUTA TOSHIYUKI
IPC: G11C29/34
Filed: 1986-05-23
Abstract: PURPOSE:To attain a comparatively fast output of intermediate voltage to an output terminal when an error occurs, by using a complementary push-pull output MOSFET containing a capacitor set at its gate as a circuit which produces the output voltage of an intermediate level. CONSTITUTION:When an error signal ERR is produced, the potential of a common source between the MOSFETs Q9 and Q10 is reduced relatively with respect to the gate voltage (Vcc/2+Vthn1) of the FETQ9 since the potential of an output terminal Dout is kept at a low level. When this difference voltage is set higher than Vthn2, the FETQ9 is turned on to increase the output voltage up to (Vcc/2+Vthn1-Vthn2). Here it can be avoided that the potential of the gate of the FETQ9 is at a low level owing to a fact that a capacitor C3 is provided to said gate. Therefore, the FETQ9 rises the terminal Dout up to an intermediate voltage level from a low level at a high speed with comparatively large conductance.

Title: High-speed writing system
Inventor: HIRAOKA KAORU
IPC: G06F3/06
Filed: 1978-09-22
Abstract: PURPOSE: To enable the writing command source to shift quickly to the next process by providing the high-speed writing means which carries out writing from the 1st to 3rd memory means plus the low-speed writing means to carry out writing from the 3rd to 2nd memory means respectively.  
     CONSTITUTION: When writing command source unit 3 transmits the data writing command to writing means 5, high-speed writing means 51 secures the buffer into which the data is to be put at intermediate memory device 4. At the same time, the data which is desired to be written into major memory device 2 from main memory device 1 is drawn out to be stored into the buffer secred. With end of this storage, means 51 transmits immediately the writing end signal to unit 3. Receiving this signal, unit 3 can proceed to the next process earlier than when the writing command is given directly to device 2. On the other hand, means 51 informs the writing position to the buffer of device 4 and low-speed writing means 52 each. Thus means 52 writes the buffer contents of designated device 4 into the designated position of device 2.
