Title: Polarized beam splitter
Inventor: KIMURA YASUO
IPC: G02B5/30
Filed: 1988-06-15
Abstract: PURPOSE:To contrive the reduction of cost and the improvement of mass productivity by disposing a metallic surface relief grating having a specific relation with the wavelength lambda of incident light to such a position where approximately the Bragg angle of the grating is attained with respect to the incident light. CONSTITUTION:The metallic surface relief grating 9 having the pitch nearly equal to the wavelength lambda of the incident light and having the grating groove depth (d) of a nearly 0.25lambda is so disposed that the light enters the grating at the angle (approximately Bragg angle thetaB') approximate to the Bragg angle of the grating. The reason for averting the coincidence of the incident angle with the Bragg angle is to separate the 1st order diffracted light and the incident light. For example, gold 16 of a suitable thickness is deposited by evaporation in a substrate 15 and a grating pattern is formed thereon by a photoprocess; thereafter, the gold is etched by a wet or dry etching method with the photoresist as a mask to form the gold surface relief grating 17. The material cost and the man-hours of production are drastically reduced in this way and the polarized beam splitter is obtd. inexpensively with the high productivity.

Title: Detecting method for lack of tape in tape winder
Inventor: OGURA KATSUTOSHI
IPC: G01V8/10
Filed: 1987-06-10
Abstract: PURPOSE:To prevent the improper detection of lack of tape by providing a black color part on the outer surface of the core member of a tape pad installed on a tape winder and detecting the exposure of the core member with a photo sensor. CONSTITUTION:A black color part 13 is provided on the outer surface of a core member 12 for winding a tape 11, and a reflecting type sensor 4 in which light emission and light receiving are integrally formed is used for a photo sensor. Thereby, at the time of detecting lack of tape, the light of the photo sensor 4 is reflected by the tape 11 and a tape winding operation is carried out while detecting this reflected light. As the remaining quantity of the tape is reduced starting to expose the black color part 13 on the surface of the core member 12, the reflecting light is sharply lowered. By detecting this condition with the photo sensor 4, the equipment is stopped to carry out the replacement of the tape pad 1.

Title: Valve system of four cycle engine
Inventor: YAMADA TETSURO
IPC: F01L1/26
Filed: 1989-06-07
Abstract: PURPOSE:To make it possible to lessen the roughness of the internal surface of a combustion room by making the length from the end face of a cylinder head on the side of a combustion room to the shaft center of an inlet camshaft longer than the length to the shaft center of an outlet cam shaft. CONSTITUTION:In an engine 1, the length L from the end face 5a of a cylinder head on the side of a combustion room to the shaft center 21a of an inlet cam shaft 21 is made longer than the length l to the shaft center 32a of an outlet cam shaft 32. This sufficiently separates the cross points of the respective air inlet valves 15 and 15'' which are made to translatingly engage with an inlet cam shaft 21 from the end face 5a on the side of the combustion room. For this reason, the crossing angle between the shaft center 15a of the air inlet valves 15 on both sides and the shaft center 15a' of the middle air inlet valve 15' seeing from the axial direction of the inlet cam shaft 21 becomes small by the distance from the combustion side end face. As a result, the angles alpha'(alpha=alpha') between the end faces 17a and 17a' of valve seats 17 and 17' becomes small. Therefore, the roughness of the internal surface of a combustion room 8.

IPC: G03F3/10
Filed: 1989-06-08
Abstract: PURPOSE:To easily and more satisfactorily proofread a picture by applying heat and pressure to a toner image to bury the toner image in an overcoat layer. CONSTITUTION:Heat and pressure are applied to a toner image 15, which is formed on an overcoat layer 14 of one electrophotographic recording medium P by the electrophotographic process, by rolls 16 and 17 to bury the toner image 15 in the overcoat layer 14, and the electrophotographic recording medium itself is used as a proof. When the toner image is buried in the overcoat layer and the recording medium is directly used as a proof in this manner, proofreading is facilitated because a color picture superior in half tone and density gradation is easily formed on the white recording medium.

Title: Electric discharge machine
Inventor: FUTAMURA SHOJI
IPC: B23H1/02
Filed: 1987-06-12
Abstract: PURPOSE:To prevent the introduction into arc discharge caused by the short circuit between a work piece and an electrode by allowing a gate means to be returned to a closing mode after an elapse of an electric discharge pause time set in advance since the decay of discharge current has been detected. CONSTITUTION:When a gap between a work piece 1 and an electrode 2 reaches the range of possible discharge by the operation of a source control device, discharge current starts flowing. After an elapse of an electric discharge time set in advance since the aforesaid discharge current has been detected, a gate control means 5 controls a gate means 4 to be set to an opening mode so as to allow voltage applied by a power source means 3 to be off. In the second place, when the decay of discharge current is detected by a discharge current decay means 7, the gate control means 5 allows the gate means 4 to be returned to a closing mode, thereby allowing the introduction into discharge to be repeated after the elapse of a discharge pause time set in advance, that is, after the restoration of insulation of working fluid in the gap between the electrodes. This constitution thereby prevents arc discharge caused by the short circuit between the work piece and the electrode, thereby enabling working accuracy to be maintained.
