Title: Cylinder head of internal combustion engine
Inventor: MORI KAZUHIKO
IPC: F02F1/00
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a cylinder head which adopts a thermal sprayed layer excellent in wear resistance as its sliding surface. SOLUTION: In a cylinder head, a valve seat 15 that is attached to and removed from an intake/exhaust valve is constructed of a stack formed by thermally spraying thermal sprayed particles and accumulation of them as flakes, and the working face 151 of the valve seat 15 that in attached to and removed from the intake/exhaust valve is formed at an angle of 0 to 60 degrees to the direction P of accumulation. Since the end faces of the numerous particles flatly accumulated are exposed at the working face, a stabilized friction characteristic is provided. Also, since each particle extends in the direction of depth, they are less likely to break away, resulting in enhanced wear resistance.  Also, since each particle extends in the direction of depth, heat conductivity in the direction of depth is high and surface heat is therefore easily transferred to a cylinder main body, facilitating cooling of surface temperature.

Title: High frequency power amplification circuit
Inventor: ZUSHI TAKAJI
IPC: H03F3/189
Filed: 1988-11-09
Abstract: PURPOSE:To stabilize the operation of the title circuit extending over a wide band, and to reduce an element area by constituting the circuit by using an inductor in common without inserting a series resonance circuit directly into a main circuit to execute amplification. CONSTITUTION:The circuit is constituted by using the inductor 11 or the inductor 21 in common together with the series resonance circuits 24, 26 without inserting the series resonance circuits 24, 26 directly into the main circuit. Thus, the series resonance circuits 24,26 become difficult to act as elements to cause parasitic oscillation for the input signal of frequency lower than f/2, and the stability of the operation is improved. Besides, since f/2 oscillation is apt to occur at the lower frequency of the frequency band of an amplifying signal, the frequency domain of the stable operation can be extended toward a lower side, and the stable amplification can be performed in the wide band.

IPC: G01N29/04
Filed: 1991-10-29
Abstract: PURPOSE:To enable closing echo height of outside face flaw to echo hight of inside face flaw and thereby to detect the outside face flaw highly accurately by processing the artificial flaw depth of the inside face larger than a specific value and by executing compensation function of outside face echo height (DAC). CONSTITUTION:When executing a flow detection of a thick-wall steel pipe by a ultrasonic flaw detection, sensitivity difference of both comparing test pieces 5 one of which has an outer surface artificial flaw 7 of 5 % depth hOD to wall thickness of the steel pipe, and another one of which has an inner surface artificial flaw 6 of depth hID smaller than the depth of the outer surface artificial flaw 7, is calibrated so as to stay within the predetermined echo height, by using both test pieces. Then, flow detection is carried out after compensation by the use of a DAC. By processing the depth of the inside face artificial flaw 6 to be smaller than 5 %t and conducting the DAC compensation, the echo height of the outside face flaw can be made close to the echo height of the inside face flaw and therewith the outside face flaw can be detected highly accurately.

Title: Projection aligner
Inventor: TAKUBO MINORU
IPC: H01L21/30
Filed: 1990-10-22
Abstract: PURPOSE:To conduct high precision exposure and at the same time arrange so that exposure patterns can be exposed at plural places, by holding an exposed member in a perpendicular state by means of a holding mechanism. CONSTITUTION:Exposure light from an optical source 14 is radiated to an exposed member S through a mask M and a projection lens PL arranged on a horizontal optical axis, and a mask pattern is exposed at the member S. At this time, as the member S is held perpendicularly by an exposure member holding mechanism 50, bending due to its self weight is prevented and the flattening of an exposure surface can be accomplished, and so the mask pattern can be exposed with high precision. Also, the member S is movable at least within a surface meeting at right angles with the horizontal optical axis, by means of the mechanism 50, so a plurality of mask patterns can be exposed at the member S by 'step and repeat', and the through-put of an exposure device can be improved. As a result, a plurality of comparatively large patterns can be exposed with high precision at an exposed member of a large area by means of 'step and repeat'.

Filed: 1988-11-10
Abstract: PURPOSE:To eliminate the necessity of a full-flag discriminating process to be performed by means of a processor by monitoring the full state of a memory by means of hardware and controlling ON/OFF of clocks in accordance with the monitoring output. CONSTITUTION:When writing operations of effective informations to a first in first out (FIFO) memory 1 are required in a processor 2, the processor 2 sets a write signal 13 to an L level against the memory 1. In response to the L level, a D-FF 5 samples a full flag 10, and, since the full flag 10 is at an L level which indicates that the flag is not full, a gate 4 is turned on. Accordingly, writing of information is performed to the memory 1. In the case a writing request is made from the processor 2 when the memory 1 is keyed to 'full', the output of the D-FF 5 changes and the gate 4 is turned off, since the flag 10 is at a H level. Accordingly, supply of clocks 14 to the processor 2 is stopped and the processor 2 stops the writing of information to the memory 1.
