Title: Clock input circuit
Inventor: YAMADA TOSHIMI
IPC: G06F1/32
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption in an object by controlling an operation reference clock to be supplied to the object. SOLUTION: Two OR gates 31 and 32 supplied with the operation reference clock CK0 and call signals SC respectively supply the clock CK0 to the logic circuits 41 and 42 of the object when the call signal SC is 'L' and stop the supply when the call signal SC is 'H'. By the supply stoppage of the clock CK0 , the power consumption of the logic circuits 41 and 42 is reduced. In the meantime, the clock CK0 and the clock CK1 are supplied to the OR gate 33. For the clock pulse of the clock CK1 , a cycle is longer and a pulse width is longer than the clock CK0 . The OR gate 33 supplies the clock CK0 to the logic circuit 43 while the clock pulse of the clock CK1 is supplied. Thus, since the logic circuit 43 is intermittently operated, the power consumption is little.

IPC: B23H7/04
Filed: 1983-02-09
Abstract: PURPOSE:To prevent deteriorations of working accuracy and stability in accordance with the change of thickness of a work piece by a method wherein servo- feeding is effected so as to coincide an average inter-electrode voltage with a reference voltage and the sensibility of the servo is increased when a difference between the average inter-electrode voltage and the reference voltage has become higher than a predetermined value. CONSTITUTION:In a wire-cut electric spark machining, the servo-feeding of a wire electrode is effected so as to coincide the average value of the inter-electrode voltage with the reference voltage. When the absolute value of a difference voltage ER=Vg-Vs, which is the difference between the average inter-electrode voltage Vg and the reference voltage Vs, is larger than a value V0, the sensibility of the servo is increased to permit to respond in high speed when the thickness of the work piece is changed.

Title: Piezoelectric oscillator
Inventor: FUJII SHIYUUZOU
IPC: H03B5/32
Filed: 1984-02-07
Abstract: PURPOSE:To relax the standards of a piezoelectric oscillator and also to eliminate mutual interference between piezoelectric oscillators by giving an oscillation control signal to one of the plural oscillating circuits each including a piezoelectric oscillator and an inverse circuit so as to activate the circuit. CONSTITUTION:The oscillating circuits 10, 20, 30 consist respectively of piezoelectric oscillators 13, 23, 33 and oscillating inverter circuits 16, 26, 36. When a high level voltage is impressed to a terminal 81, since an output of the inverter circuit 41 goes to a low level voltage, the oscillating circuit 10 is oscillated by a frequency decided by the piezoelectric oscillator 13. In impressing a low level voltage to terminals 82, 83, an output voltage of the inverter circuits 42, 43 goes to a high level voltage and the oscillating circuits 20 and 30 are not oscillated. Thus, only an output of the oscillation circuit 10 is obtained at an output of an OR circuit 60, and in impressing properly a low level voltage or a high level voltage to the terminals 81-83 similarly, the oscillating circuit having a desired oscillating frequency is selected.

Title: Identification mark reading method
Inventor: NAMAE TAKAO
IPC: H01L21/027
Filed: 1982-02-10
Abstract: PURPOSE:To simply discriminate an identification mark from other marks and chip patterns in reading and to use a wafer effectively, by a method wherein an identification  mark is applied to that position in the peripheral part of a substantially circular wafer  having a cut part in a part thereof which is a predetermined distance away from the  cut part, and the identification mark is read in relation to the detection of the cut part. CONSTITUTION:With a wafer 1 rotated by a motor 3 through a stage 2, when a point  A in a cut portion S comes directly below a light source 4L, a control signal generator  circuit 8 generates a control signal and continues to send the signal to a gate circuit 7  until a point B in the cut part S comes directly below the light source 4L. In the meantime, an identification mark provided on an imaginary circle F on the wafer (1) is  irradiated with a light beam from a light source 5L, and a reflected light corresponding to the identification mark is detected by a photoelectric detector 5D. The output  of the detector 5D is sent to the gate circuit 7 through a pulse generator 6. During the  period in which the control signal is sent from the control signal generator circuit 8,  the gate circuit 7 delivers to an electronic computer 9 a pulse signal corresponding to the identification mark sent from the pulse generator 6. The computer 9 decodes the  pulse signal to identify the kind of the wafer.

Title: Heat exchanger
Inventor: NAKAMOTO MITSUYOSHI
IPC: F28F13/18
Filed: 1983-02-08
Abstract: PURPOSE:To enable the heat of jets to be utilized effectively without making a heat exchanger large in, size by providing a porous metal between jet ports of a heat transfer medium and a heat transfer wall, securing the porous metal to the heat transfer wall, and allowing the jets to transfer their heat to the heat transfer wall via the porous metal after the jets hit against the heat transfer wall, and the jet stream pass through the porous metal. CONSTITUTION:The jets 16 of a high temperature heat transfer medium are jetted through the jet ports 9 formed regularly in a jet outlet plate 10 into a jet section 11. The jets 16 pass through the porous metal 13 and hit against the heat transfer wall 12. While the jets 16 transfer their heat to the porous metal 13, they strike the heat transfer wall and the heat is transferred. Part of the jets 16 hit against the heat transfer wall flowing along the heat transfer wall, while major parts thereof flow back into the porous metal 13, passing through the porous metal to transfer the remaining heat thereto, and is discharged from the jet port 15. As the heat of the discharged heat transfer medium is exchanged efficiently, the temperature thereof becomes low. As the porous metal is desirable to be of a high porosity so that the resistance to the flow of the heat transfer may be less, and also desirable to have a large heat transfer area so as to be able to transfer heat efficiently. Thus the present heat exchanger having the same volume as that of the prior art can recover a large amount of heat so as to utilize the heat of jets efficiently.

Title: Radar system
Inventor: SUEHIRO NAOKI
IPC: G01S13/87
Filed: 1986-02-04
Abstract: PURPOSE:To prevent two radars from imparting interference to each other though both radars have the same frequency band, by respectively allotting two specific systems to two radars as transmission signals. CONSTITUTION:A system A of a system length N represented by formula I and a system B of a system length N represented by formula II are respectively allotted to two radars as transmission signals. If it is assumed that respective radars receive signals using the matched filters of the allotted systems, when the reflected wave of the signal A transmitted by oneself was received, the own phase correlation function signal A*-A of the signal A is outputted from the matched filter. When the signal B transmitted by the other radar or the reflected wave thereof was received, the mutual phase correlation function signal B*-A of A, B is outputted from the matched filter. Because the signals A*-A, B*-B are in false pulse form and take a small value with respect to all of shifts, the interference between two radars is light.
