Title: Semiconductor device of pin grid array type
Inventor: KITANO MAKOTO
IPC: H01L23/12
Filed: 1990-06-11
Abstract: PURPOSE:To realize a small size and a high density while a matching property to a mounting board is being kept by a method wherein lead pins to be connected electrically to outside terminals are arranged also in a semiconductor-chip mounting part on the board. CONSTITUTION:Metal lead pins 1 are inserted in the whole region of a board 2; a semiconductor chip 4 is bonded, via an adhesive layer 3, to the upper part in the central part of the board 2; in addition, the semiconductor chip 4 and metal interconnections 5 formed on the surface of the board 2 are connected electrically by using bonding wires 6; after that, the semiconductor chip 4, the bonding wires 6, the metal interconnections 5 and the like are sealed with a resin. Before they are sealed with the resin 7, a frame member 9 which is used to stop the flow of the resin 7 prior to its solidification is bonded to the surface of the board 2 via the adhesive layer 8. The material used for the frame member 9 is the same resin material or the like as that for the board 2. Thereby, the overall dimensions of a device can be made small without changing the pin diameter and the interval between pins of the metal lead pins which are prescribed in order to keep the matching property to outside terminals.

Title: Alignment method and exposure method
Inventor: SHINOZAKI TADAAKI
IPC: H01L21/027
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To execute alignment of a board without lowering through put while maintaining desired alignment accuracy by processing an image by a template matching method, and setting frequency of fetching of an image of an alignment mark according to obtained resemblance. SOLUTION: An image of alignment marks 7, 8 of a mask 1 and a plate 3 is imaged by a CCD camera 16 and fed to an image processing unit 19. In the image processing unit 19, resemblance RM of the mask 1 is found by a template matching method by using a template of the mask 1 to a picked-up image and a position wherein resemblance RM is minimum is detected as a mark position of the alignment mark 7 of the mask 1. It is judged whether or not a value of the found resemblance RM of the mask 1 is larger than 20; if a value of resemblance is not more than 20, it is judged that a mark position of the alignment mark 7 of the mask 1 is detected with a predetermined accuracy.

Title: Electrostatic induction thyristor
Inventor: NISHIZAWA JUNICHI
IPC: H01L29/74
Filed: 1986-06-26
Abstract: PURPOSE:To decrease electrostatic capacitance of a driving gate, to substantially nullify the effect of storing carriers in channels and to increase current gain in an electrostatic induction thyristor, by employing a divided gate construction for the thyristor so that it can perform high-current switching at a high speed. CONSTITUTION:N<+> regions 8 are arranged in stripes, mesh or the like on the interface between an n<-> region 4 and an anode region 7 and are connected directly with the anode region by by external electrodes, so that electrons injected from sources 1 enter into the n<+> regions 8. There is provided a single driving gate for controlling conducting and breakaing operations, while fixed potential gates 3 and 8 are provided, respectively, for absorbing holes and electrons, whereby a static induction thyristor is allowed to have an extremely high switching speed. If the fixed potential gates 3 and 8 are reversely biased with respect to the cathode 1 and the anode 7, respectively, by independent power sources, their effect of absorbing holes and electrons becomes remarkably strong. Simultaneously, substantially no current flows through the driving gate either during conduction or during breaking. Thus, the thyristor is allowed to operate with extremely high current gain.

Title: Cell for block isolation
Inventor: INOUE KEISUKE
IPC: G01R31/28
Filed: 1989-06-13
Abstract: PURPOSE:To efficiently test a circuit by holding test data in an FF circuit to send it to another block after sending data of a test data input terminal to a test or normal data output terminal in the scan mode. CONSTITUTION:A cell consists of normal data input and output terminals IN and OU, test data input and output terminals SI and SO, a switch means TG1 which is turned on at the time of the normal mode to send normal data from the terminal IN to the terminal OU, and inverters IV3 and IV4 connected with the means TG1 between them and is provided with the FF circuit where data from the terminal SI is stored. In the scan mode, the FF circuit sends data from the terminal SI from the terminal IN to the terminal OU or SO and stores this data to send it to another block thereafter, and this operation is repeated for each time of test data input. Thus, test data is transferred to many cells through one input terminal in serial and the reverse transfer is possible, and test data is given to the circuit block through the cell without the increase of the number of input and output terminals to control it, and it is easily observed.

Title: Refrigeration cycle controller
Inventor: OIKE TATSUYA
IPC: F25B1/00
Filed: 1988-06-17
Abstract: PURPOSE:To enable stable control to a desired cooled condition according to a load by providing a means for correcting a set point based on the quantity of regulation by a refrigerant quantity-regulating means. CONSTITUTION:A capability-regulating means M5 regulates the capability of a variable-capability compressor M1 in such a direction that a physical quantity associated with the pressure of a refrigerant vapor generated by an evaporator M4 according to a load variations or the like is brought to a set point. On the other hand, a refrigerant quantity-regulating means M6 regulates the quantity of a refrigerant expanded by an expansion valve M3. A set point-correcting means M7 corrects the set point, based on the quantity of regulation by the regulating means M6. For example, when the load is increased and the degree of superheat or temperature is raised, the quantity of refrigerant expanded is increased by the regulating means M6. The correcting means M7 corrects by decreasing the set point, i.e. a set point of refrigerant vapor pressure, based on the quantity of refrigerant thus increased, whereby a set point of refrigerant pressure is lowered. When the load is decreased, a process reverse to the above is carried out.

Filed: 1977-12-19
Abstract: PURPOSE: To eliminate the overload state of CPU by transmitting the data of the buffer register to the cue memory busy-idle detector circuit when only the specific input/output address exists and transmitting the data via CPU only the idle state of the cue memory is replied.  
     CONSTITUTION: The inquiry signal to inquire whether or not the data of buffer register 4a in data process part 4 can be transmitted to cue memory 5a is transmitted to cue memory busy-idle detector circuit 5b from inquiry circuit 4b only in case the input/output address received from CPU1 is the specific input/output address. Then the answer signal sent from circuit 5b is transmitted to circuit 4b to decide whether the data of register 4a is transmitted to memory 5a to inform the idle- busy state of memory 5a to CPU control part 1a. Thus, part 1a transmits the data to data processor 3 only when informed that memory 5a is idle, eliminating the soft and hard overload which is applied to CPU1 for the retransmission of the data.
