Title: Grinding method with cup-shaped grinding wheel
Inventor: UCHIYAMA TSUNEO
IPC: B24B7/22
Filed: 1984-09-14
Abstract: PURPOSE:To enhance the working effectiveness by performing grinding with the internal edge of a cup-shaped grinding wheel, and thereby efficiently processing the work to be ground made of a brittle substance such as wafer. CONSTITUTION:A grinding wheel 4 and a wafer 2 are located so that the wheel 4 surrounds the wafer 2, and the wheel 4 is moved in the direction of arrow B. At this time, the angle theta formed by the tangential line on the outside edge of the wafer 2, in the position where the wheel 4 cuts into the wafer 2, with respect to the tangential line on the internal edge 6 of the wheel 4 will be an obtuse angle. Therefore the outside edge of the after 2 is not likely to generation of cracks, so that the margin for grinding can be set a large value. Further, supply of the grinding liquid from the spindle 3 will provide adequate feed of the grinding liquid to the point to be ground, which will contribute to enhancement of working efficiency in grinding.

IPC: G01F15/02
Filed: 1984-09-14
Abstract: PURPOSE:To make the quantity of discharge found from the opening of a discharge data approach the real quantity of discharge by compensating the former value by the water level changing ratio of a storing reservoir. CONSTITUTION:In a measuring instrument of the quantity of discharge from a gate, the water level of the storing reservoir 6 which is found out by a water level meter 7 is smoothed and held at a smoothed water level H by removing the influence of water level variation due to waves of the storing reservoir 6. A water level variation rate calculating part 153 inputs the water level H, outputs its water level changing rate DELTAH and then outputs the water level H and the opening C of the discharge port 8 obtained by a gate opening meter 9 to a gate opening base discharge volume calculating part 152 to obtain the quantity Q0b of discharge from a gate opening base. A reference water level changing rate setting part 154 outputs a reference water level changing rate DELTAH0 at the water level H and the opening C. The quantity Q0 of discharge is obtained from a discharge volume compensating value Q0 obtained by inputting the deviation DELTAh between the changing rate DELTAH0 and the changing rate DELTAH obtained from the calculating part 153 in a discharge volume compensating value calculating part 155 and the quantity Q0b of discharge from the gate base. Namely the quantity Q0 of discharge is compensated by the deviation value DELTAh between the reference water level compensating rate DELTAH0 and a current water level changing rate DELTAH and approach to the real quantity of discharge.

Filed: 1987-08-01
Abstract: PURPOSE:To reduce the number of components, namely, to simplify the structure of a temperature compensating circuit, by commonly using a detected temperature signal generated from one temperature-pulse width converting circuit for a plurality of temperature compensating circuits each constituted by a voltage dividing means and a switching means. CONSTITUTION:A temperature-pulse width converting circuit X oscillates a pulse width signal Vp which changes the duty ratio D(T) (time ratio of a pulse width t1 during H time with respect to a pulse repeating cycle T0) in accordance with the temperature detected by a temperature sensing element RT. Then, in a plurality of temperature compensating circuits YN (N=1, 2...), a measuring signal VN1 inputted by an input terminal IN is divided into a big signal VNB and a small signal VNS(VNB>VNS) by a voltage dividing means (resistor) CN. The signals VNB and VNS are supplied to a switching means (switching element) DN to be outputted alternately to an output terminal ON in accordance with the H/L change of the signal VP from the converting circuit X. In other words, a weighted mean of the signal VNB or VNS is outputted as a temperature compensated signal VNO, and therefore a simple and cheap temperature compensating circuit can be realized.

Abstract: PURPOSE:To enable qualitative and quantitative analysis of several amino acids simply, particularly imino acid such as proline, with high sensibility by allowing a sample contg. amino acid to react with O-phathaldehyde, etc. to form fluorescent compd. CONSTITUTION:Buffer soln. 11 is fed to a detection part 5 through a passage 1, column 3, and a passage 4. Then, a sample contg. amino acid is introduced with a syringe from an inlet 2 to the passage 1. The introduced sample is transferred to the column 3 where it is separated into each amino acid component and led to a passage of an eluate. The separated phases of each component are then fed to an injection reaction tube 6 successively. Hypochlorous acid is injected into the reaction tube 6 in this stage. Thus, imino acid type sec-amine acid such as proline is transformed to primary amino acid in a preliminary reaction tube 7. Each separated phase is then introduced into a mixing reaction tube 7. In this stage, O-phthaldehyde and N-acetyl cysteine are injected into the reaction tube 7. Thus, the prim. amino acid component in each separated phase is transformed to fluorescent condensed heterocyclic derivs. and transported to the detection part 5.
