Abstract: PROBLEM TO BE SOLVED: To perform highly accurate chamfering work by performing chamfering work by grinding the peripheral edge of a wafer little by little by a grinding wheel by relatively approaching the grinding wheel rotating at a high speed and the wafer. SOLUTION: An outer periphery working grinding wheel 108 is driven so as to rotate at a speed of a range where the peripheral velocity is not less than 1,000 [m/min], desirably, 1,500 to 3,000 [m/min]. A wafer table 100 is driven so as to rotate at a speed of a range where peripheral velocity of the held wafer W is not less than 30 [m/min], desirably, 100 to 1,000 [m/min]. The wafer W sent toward the outer periphery working grinding wheel 108 contacts in the peripheral edge with a groove 108a of the outer periphery working grinding wheel 108. Even after this contact, the wafer W is sent toward the outer periphery working grinding wheel 108 at a prescribed feed speed of 0.3 to 3 [mm/sec], thereby performs chamfering work on the circular part of the wafer W by being ground an extremely small quantity by an extremely small quantity by the outer periphery working grinding wheel 108.

Title: Fuel injection pump
Inventor: ISHIMOTO YOSHIKI
IPC: F02M59/26
Filed: 1989-11-29
Abstract: PURPOSE:To achieve high pressurization of a fuel by specifying the hardness of a base material of a barrel, and applying a surface hardening process to the inner circumferential part of a cylinder hole in such a way that its hardness is higher than that of the base material, so as to make the hardness of a seat surface almost equal to that of the barrel itself. CONSTITUTION:A barrel 4 receives a refining heat treatment so as to define the hardness of its base material as HV300-400, while a seat surface 8 is of almost the same hardness as that. When the sheet of a delivery valve 10 is forcibly pressed to the seat surface 8, the seat surface 8 as well as its vicinity are deformed elastically, and come into contact liquid tight with each other through the entire surface. The fuel in a fuel pressurization chamber 11 is not leaked from between the seat surface 8 and the delivery valve seat, whereby the fuel in the pressurization chamber 11 can be maintained at a high pressure level. Since the inner circumferential part of a cylinder hole 6 is subjected to a carburizing process, and its surface hardness is made higher than that of the base material, the early abrasion of the inner circumferential surface of the cylinder hole 6 due to the sliding connection of a plunger 9 can be prevented.

Besides, the cosine of the average incident angle of the bundle of the rays made incident on the scheduled point on the lens surface 11 is obtained. Then, the shift quantity of the surface in the optical axis direction as much as unit wavelength is obtained from the cosine.  Based on the additional quantity of the optical path length, difference quantity between a real optical path which should be given by the shift in the optical axis direction at the point is obtained. Then, the shift quantity in the optical axis direction at the point on the lens surface is decided based on the shift quantity in the optical axis direction as much as the unit wavelength and the optical path difference.

Title: Non-sinusoidal wave oscillating circuit
Inventor: KAWAMOTO HIROSHI
IPC: H03K3/033
Filed: 1986-12-26
Abstract: PURPOSE:To attain simple and proper measurement of a leakage characteristic of a switching element controlling the charge/discharge of a capacitor by forming a circuit setting the switching element to the steady-state OFF-state forcibly by an external signal within a control circuit. CONSTITUTION:When an external trigger signal Ts rises to an H (high level) after being at an L (low level) once in the stable steady-state, the switching element Q1 is set to the OFF-state. Thus, a capacitor Cx is in the charging state and its charge/discharge potential Vp rises. The OFF-state of the switching element 1 is transient and does not last long, and when the charge/discharge potential Vp of the capacitor Cx exceeds a prescribed reference potential Vp, the detected output of a potential detection means CP is fed back to a logic circuit 12 and the switching element Q1 is restored again to the ON-state. Thus, the electric charge charged in the capacitor Cx is discharged and the element Q1 is restored to the original stable steady-state.
