Patent JP-H01218110-A (JP)
Title: Ecl-ttl level conversion circuit
Inventor: IKEUCHI TAKAO
IPC: H03F3/343
Filed: 1988-02-25
Abstract: PURPOSE:To prevent saturation of a transistor(TR) or to minimize the effect thereby quickening the switching operation by inserting a resistor to a TR relating to a low level of a TTL output. CONSTITUTION:A resistor 13 is inserted to a TR 1. Thus, no excess current flows to the base of the TR 1 and no excess current flows to the base of a TR 4, then the TR hardly reaches the saturation region even with the dispersion in the VF of a Schottky barrier diode. Moreover, a resistor 14 is connected to the base of the TR 4. Even when the base of the TR 1 reaches a low level, that is, the TTL output reaches a high level, since a current always flows to the resistor 14, when the TTL output changes from a low level to a high level, the minority carrier storage charge on the base of the TR 4 is quickly discharged. Thus, high speed operation is realized.

Abstract: PURPOSE:To prevent the generation of mismatching in the thermal expansion coefficient of LSI by a method wherein, in a metal foil adhered laminated sheet formed by superposing prepreg, in which resin is impregnated into core material, and metal foil, they are heated up under pressure, the coefficient of elasticity is set at a prescribed value or higher and thermal expansion coefficient is set at the prescribed value or lower. CONSTITUTION:Core material (e) is manufactured by forming an inner layer pattern on the surface using a prepreg (d) which is formed by impregnating epoxy resin into the core material of glass of high strength and high elastic modulus and then they are dried up. The core material of glass cloth, having the elastic modulus of 7450kgf/mm<2> and the thermal expansion coefficient of 3.5X10<-6>/ deg.C, is used. The epoxy resin is the resin having high heat resistance and the glass transition point of 170 deg.C or higher. As above-mentioned, the thermal expansion of the epoxy resin and the metal foil can be suppressed by using the glass cloth for the core material.

Title: Conversion method of virtual address
Inventor: RAJIBU GUPUTA
IPC: G06F12/10
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To shorten a conversion time from a virtual address of conversion lookaside buffer (i.e., TLB) to a physical address in a virtual storage system. SOLUTION: TLB consists on N entries which has a virtual tag, valid bits, a physical page number and an entry space tag. In a conversion process, an explicit address contained in a virtual address is divided into an indirect address and a TLB index, and the TLB index is compared with the virtual tag. Comparison of the indirect address and the entry space tag is carried out, preceding the comparison of the TLB index. When both TLB index and indirect address comparisons coincide with the same TLB entry, a physical page number is outputted as a part of a converted physical address which corresponds to the virtual address. Thereby, fetch and comparison operations of space register of conventional technique are omitted, and a virtual address conversion time is extremely shortened.

Abstract: PURPOSE:To make a charge detection circuit in a wide dynamic range in high S/N by a method wherein the first reset gate and the second reset gate are formed splitably to be opened and closed at a timing shift. CONSTITUTION:N type channels 16a, 16b are formed between n<+>type diffused layers 13 and 18 while reset gates 17a, 17b are formed above the layers 13, 18. The reset gate 17a is closed at a time t1.

Filed: 1982-03-17
Abstract: PURPOSE:To reduce water cutoff regions at parts on the downstream of heat- transmitting pipes and contrive to enhance heat-transmitting efficiency at heat- transmitting surfaces on the air side, by a method wherein projections faced orthogonally to an airflow are provided on the surfaces of fins at positions in proximity to and on the downstream side (with respect to the airflow) of each row of heat-transmitting pipes. CONSTITUTION:The fins 1 are provided with fin collar parts 4 formed by burring at regular intervals, and the heat-transmitting pipes 2 are passed through the fin collar parts 4. The projections 5 faced orthogonally to the airflow are provided on the surfaces of the fins 1 at the positions in proximity to and on the downstream side (with respect to the airflow passed in the direction of arrows) of each row of the pipes 2. Accordingly, the airflow passing in the direction of the arrows is shut off by the projections 5 provided at the parts on the downstream of the pipes 2, and enters into the parts, thereby reducing the water cutoff regions. Accordingly, since heat is sufficiently exchanged between the fins 1 of the pipes 2 and the airflow even in the regions on the downstream of the pipes 2, the heat-transmitting performance of the heat exchanger can be enhanced.

Filed: 1995-03-03
Abstract: PURPOSE: To form a diffused region having predetermined impurity concentration and a shape by using a photoresist containing resin having a specific value or more of weight mean molecular weight as a main ingredient. CONSTITUTION: A polycrystalline silicon layer 2 is deposited on a silicon wafer 1 via an oxide film, coated with photoresist 3, and prebaked.
