Title: Collet chuck device
Inventor: KONDOU MASUO
IPC: B23B31/20
Filed: 1983-12-19
Abstract: PURPOSE:To raise the precision of the work holding action and to perform the precise machine processing, by constructing a device with a collet member, by whose outer circumferential surface, a held work is pierced and the work can be fastened, and with a thrust conveying member which connects a thrust member to a sliding member. CONSTITUTION:In a machine tool, such as a lathe, a fixing member 3 is fixed to a main shaft 2, by a bolt 15. In case a thrust member 5 is advanced/retreated by a cylinder mechanism, a sliding member 8 is advanced/retreated by the action of the thrust member 5. When the sliding member 8 is advanced, a male taper surface 7 of the sliding member 8 and a female taper surface 9 of a collet member 10 are pressed together, the collet member 10 is expanded by the said pressing action, and consequently, a held work W can be fastened by the outer circumferential surface of the collet member 10. When the sliding member 8 is retreated, the pressing action of the male taper surface 7 and a female taper surface 9 is loosened, the size of the collet member 10 is restored, and the held work W can be released. In this way, the precision of the work holding action can be raised, and the precise machine processing can be performed.

Title: Semiconductor integrated circuit
Inventor: SAKATA YOSHIO
IPC: G06F11/22
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To miniaturize a size, to reduce power consumption and to reduce clock skew by providing a control signal generation circuit which generates a control signal based on 1st and 2nd clock signals and a mode setting signal and plural scan path circuits which are operated and controlled by the generated control signal. SOLUTION: A control signal generation circuit 150 generates a control signal which controls plural scan path circuits 130-K and 140-K (1≫∼) which are contained from a 1st clock signal MCK, a 2nd clock signal TCK and a mode setting signal MODE. Because of this, each scan path circuit synchronizes with a common control signal and operates. Then, an output signal from each scan path circuit that has the same circuit configuration becomes more synchronous and clock skew of the semiconductor integrated circuit 100 can be reduced. Also, because one circuit 150 is shared by plural scan path circuits, the size of the circuit 100 can be miniaturized.

Inventor: SASAKI YOSHITAKA
IPC: G11B5/39
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To obtain sufficient overwrite characteristics even when the width of a magnetic pole is decreased. SOLUTION: An auxiliary layer 20 made of a magnetic material is formed on the vicinity of the edge on an air bearing face side of an insulating layer 11 which determines a throat height. Then, an upper magnetic pole layer 16 is formed on the auxiliary layer 20. By forming the auxiliary layer 20, the volume of the magnetic layer near the position where the throat height is zero is increased by the volume of the auxiliary layer 20 compared in the case of only the upper magnetic layer 16. As the result, the saturation of magnetic flux near the zero point of the throat height can be prevented.

Title: In-furnace monitoring device for continuous electrical furnace
Inventor: AOKI MICHIRO
IPC: F27B9/40
Filed: 1990-09-10
Abstract: PURPOSE:To perform a positive sensing of an abnormal state generated in a passage in a furnace chamber by a method wherein when a light signal advancing in the passage is shielded, and an occurrence of abnormal state in the passage in the furnace is detected. CONSTITUTION:A light signal composed of a straight forwarding laser beam generated from a light emitting device 14 is received in a light receiving device 15 if there is no abnormal state in a passage 3. The light signal is comprised of a laser beam, for example, and its light passing passage is set to pass below a lower end 4a of a spaced-apart wall brick 4 placed at the most suspended position in the passage. This laser beam L passes over a baked item 12 mounted on a table plate 11 and is set at such a position of height not providing any trouble in movement of the baked item 12. If it is assumed that the spaced-apart brick 4 within the passage 3 is hung down due to an aging caused by heat or vibration or the like and the lower end 4a of the spaced-apart brick descends at the position where the laser beam L is shielded, the laser beam L is shielded by the spaced-apart brick 4. Accordingly, the light receiving device 15 does not receive any light signal from the light emitting device 14. Due to this fact, it is detected by an input signal of the light receiving device 15 that there has occurred an abnormal state in the passage 3.

Title: Power converter
Inventor: UCHINO HIROSHI
IPC: H02P21/00
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To enable a power converter to generate a sine-wave voltage while the number of switching times of a selfextinguishing element is suppressed by switching the element when the integrated value of the difference between a voltage command value vector indicating the voltage to be outputted from the converter and an actual voltage vector indicating the actual output voltage of the converter exceeds a set value. SOLUTION: A three-phase/two-phase converting circuit 10 decides voltage command vectors VAR and VBR from VAR=VUR-(VVR+VWR)/2 and VBR=(VVR-VWR)×(3<1/2> /2) (where, VUR, VVR, and VWR are three-phase voltage commands from a voltage command generating circuit 9). Then the differences between the vectors VAR and VBR and the voltage output vectors VA and VB of an actual voltage value vector selecting circuit 21 are calculated and an integrator computes the integrated value of the voltage differences and compares the integrated value with a radius obtained from a set boundary circle 20 and, when the integrated value is smaller than the radius, maintains the currently outputted actual voltage value vector by discriminating that the integrated value exists in the set boundary circle 20. Since a found voltage command value is used for control, the current of a power converter can be controlled and the switching loss of the converter can be reduced.

Abstract: PURPOSE:To prevent an oxide film-based deposit from adhering to the surface of a lower-layer interconnection by a treatment executed before an upper-layer interconnection is formed, to deposit a conductive material on the surface of the lower-layer interconnection, to reduce a connection defect between interconnections and to ensure their conduction by a method wherein, when a multi-layer interconnection is formed, a conductive material is formed on an interlayer insulating film. CONSTITUTION:An interlayer insulating film 12 is formed on an aluminum interconnection 11 which has been formed on a semiconductor substrate 10; a titanium film 13 as a conductive material is formed on it. A through hole is made by dry etching. After that, Ar is sputtered and etched in order to remove a transformed layer which is composed of a deposit and the like which exist on the surface of the lower-layer aluminum interconnection 11. In this case, since the interlayer insulating film 12 is covered with the titanium film 13, it is possible to prevent an oxide film-based deposit from adhering to the surface of the lower-layer aluminum interconnection again. Thereby, an interlayer-interconnection structure wherein an upper-layer aluminum interconnection 15a is connected electrically to the lower-layer aluminum interconnection 11 via titanium 13b which is conductive can be formed.

Title: Carrier chrominance signal separation circuit
Inventor: MIMOTO SEIJI
IPC: H04N9/78
Filed: 1989-09-19
Abstract: PURPOSE:To eliminate color oozing and color slippage by providing a correlator capable of obtaining the AND output of two input in analog fashion at the output side of a comb-line filter using 1H delay circuit, comparing a carrier chrominance signal with a chrominance signal component in a video signal, and outputting either small signal. CONSTITUTION:When a color video signal W formed with a luminance signal Y and a chrominance signal C is inputted sequentially from an input terminal T, the signal V is subtracted from a signal V(DL) delayed by 1H at the 1H delay circuit 11. Thereby, an operation as the comb-line filter can be performed, and the carrier chrominance signal S1 is separated. When the carrier chrominance signal is separated with the comb-line filter 13 normally, the carrier chrominance signal S1 of the comb-line filter 13 is outputted from the correlator 15. However, when the output of the comb-line filter 13 is not a normal carrier chrominance signal, the carrier chrominance signal S2 extracted with a band-pass filter 14 is outputted from the correlator 15. Therefore, the color oozing and the color slippage easy to be prominent on a screen can be eliminated.
