Title: Pin hole structure of piston
Inventor: UEJIMA HIDEO
IPC: F02F3/00
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of rigidity which may be caused by forming a recession, by coinciding the recession with an axial groove while taking advantage of a forming position of the groove. SOLUTION: A recess 15 for detaching a circlip 13 is formed conincidently with a broach groove 12 formed on a pin hole 2a so as to release a piston pin 10 from compressive deformation caused by thrust load. The broach groove, having high rigidity, is formed with the recess without deteriorating rigidity. Lubricating oil is introduced to the broach groove through the recess, for preferably improving lubricancy in the pin hole. The recess is formed so as to be housed in the broach groove. Therefore, even when burrs are formed on the edge of the recession at the time of cutting, projection of the burr is prevented from an inner peripheral surface of the pin hole toward an inner side. Additional process such as removal of the burr is dispensed with.

Title: Transfer state detecting method, transfer state detecting device, and evacuating device
Inventor: MAEHIRA KEN
IPC: H01L21/205
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To return the transfer state of substrates to a normal state by monitoring it. SOLUTION: While a substrate 4 is pulled off a suction means 2, a light emitting part 8A emits a measuring beam 11 and a light receiving part 8B opposed thereto receives it. Because the substrate 4 moves across the optical path of the measuring beam 11 while lifted up vertically by lift pins 6, a normal transfer state produces a small quantity of light screened out whereas a transfer state in which the substrate 4 is dislodged from either or both lift pins 6 produces a large quantity of light screened out. The transfer state of the substrate 4 is thus monitored or checked from the quantity of the measuring light 11 the light receiving part 8B receives and from the transition thereof.

Filed: 1989-02-27
Abstract: PURPOSE:To avoid useless time and to quicken the processing of one pattern by providing an arithmetic controller controlling the calculation of orthogonal conversion and inverse orthogonal conversion as to sn effective element only. CONSTITUTION:A highly efficient encoding and decoding device is provided with a frequency component detector g detecting the frequency component of a conversion coefficient and a controller 10 controlling the calculation of inversion orthogonal conversion.

IPC: A63F7/02
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To prevent a shooting ball from passing through a specific area when an inclining member is inclined downward to an ordinary area. SOLUTION: An inclining plate 23c to roll a shooting ball 30 toward a specific area 23a1 or an ordinary area 23a2, prevents the shooting ball 30 repelled by the inner wall surface of an inside space 23a of a variable winning device 12 from passing through the specific area 23a1 since clearance W3 formed by the side end part of the specific area 23a1 of the inclining plate 23c and the side wall surface of the specific area 23a1 of the inside space 23a is formed smaller than a diameter W20 of the shooting ball 30 when inclined downward to the ordinary area 23a2. Therefore, the number of shooting balls 30 passing through the specific area 23a1 can be accurately adjusted since the shooting balls 30 can be passed by being reliably sent to the ordinary area 23a2 when the inclining plate 23c is inclined downward to the ordinary area 23a2.

Title: Dividing of crystal substrate
Inventor: KOJIMA YASUTOMO
IPC: H01L21/301
Filed: 1982-03-18
Abstract: PURPOSE:To reduce the generation rate of deflective pellets due to chipping or flaw by a method wherein pressure applied to a crystal substrate is restricted in its application manner so as to substantially eliminate a possibility that the cleaved pellets may cause flaws with one another. CONSTITUTION:When a moving direction 26' of a roller 23 is restricted to such a direction where the moving direction 26' makes an acute angle theta' with a normal direction 25 of a particular 11-1 plane 22 to be cleaved therealong, a pellet 24' divided by cleavage is subjected to pressure which is applied sequentially from the upper portion to the lower portion of the obliquely cleaved plane, as indicated in an enclosed box with dotted circle. Thus, the cleaved pellet 24' is pushed down in a manner that it comes away from a pellet 27' to be cleaved subsequently, so that the pellets will not chip off damage with one another. This permits to reduce a generation rate of deflective pellets remarkably.
