Title: Photoelectric detector
Inventor: TATE KATSUICHI
IPC: G01S17/02
Filed: 1984-09-20
Abstract: PURPOSE:To make it possible to detect an object to be inspected without receiving the effect of external light, by collimating the output light from a light emitting element and the reflected light from a light receiving element by a circuit comprising exclusive 'OR'. CONSTITUTION:The signal from a code signal generation circuit 11, which inputs the clock signal of a timing circuit 10, is supplied to a modulation circuit 13 through a drive circuit 12. Next, the light emitting diode PD of a reflective type photoelectric apparatus 14 is subjected to ON/OFF control by the circuit 13 and light is allowed to intermittently irradiate an object 15 to be inspected while reflected light is received by a phototransistor PT. A collimation result is outputted from a collimation circuit 16 comprising an exclusive logical circuit and discriminated by a discrimination circuit 17 to be stored in memory 18. However, when the object 15 to be inspected is absent, reflected light disappears and nil output is shown. Even when it is difficult to block external light, matter can be detected.

IPC: B60W10/04
Filed: 1989-07-28
Abstract: PURPOSE:To dissolve a problem such as the response delay immediately after an action start by expanding the width of the first pulse of the pulse signal generated after detecting that the opening/closing control of solenoid valves is continuously stopped for the preset period or longer. CONSTITUTION:When the first and second pulse signals Pa and Pb with the required number of pulses are applied to solenoids 153a and 154a, the first and second normally-closed solenoid valves 153 and 154 of an actuator section 15 are repeatedly opened or closed, the pressure from a pressure source 151 applied to a cylinder tube 152 is controlled, and a clutch is operated. When the opening/closing control of solenoid valves 153 and 154, i.e., the operation of the clutch, is continuously stopped for the preset interval or longer, the width of the first pulse in pulse signals Pa and Pb for the following clutch operation is expanded, the change of the fluid pressure for a unit time is increased only at this time, and the response delay of the actuator 15 caused by the initial volume change is improved. Good clutch control can be performed.

Filed: 1991-07-10
Abstract: PURPOSE:To obtain an antigen/antibody measuring method which can largely change the light emitting amount in corresponding to the concentration variation of antigens or antibodies to be measured and is improved in measurement accuracy. CONSTITUTION:This antigen/antibody measuring method performs antigen-antibody reaction by dipping an antibody electrode 1 with antibodies 2 being fixed to its surface in a solution to be inspected and again performs the antigen-antibody reaction by adding marked antibodies 5 marked with a chemiluminescent acridinium derivative 4 to the solution to be inspected, and then, fixes the marked antibodies 5 to the antigens 3 fixed to the surface of the electrode 1. Then, after washing the surface of the electrode 1 and separating unfixed antibodies 5, the concentration of the antigens 3 in the solution to be inspected is measured by causing chemiluminescence by electrochemically reducing the oxygen dissolved in an electrolyte by using the electrode 1 as a working electrode and measuring the emitted quantity of light. This method is effective for a solution containing antigens at a concentration of about 10<-11>-10<-5>g/ml and the emitted quantity of light can be changed largely against the variation of the antigen concentration and the measurement accuracy is remarkably improved.

Title: Dry etching of aluminum-silicon-copper alloy
Inventor: TANAKA YASUO
IPC: H01L21/3065
Filed: 1987-08-05
Abstract: PURPOSE:To dry-etch an Al-Si-Cu alloy so as to increase the ratio of selection between said alloy and a resist film for thereby keeping an anisotropic configuration in conformity with the mask pattern dimensions without residual copper, by using a mixture gas of chlorine as a reaction gas and a specific amount of boron trichloride. CONSTITUTION:A mixture gas of chlorine(Cl2) and boron trichloride(BCl3) is employed as a reaction gas. Into the mixture gas, boron trichloride of 5-40vol.% is further mixed into the mixture gas. Hereby, the etching rate of the Al-Si-Cu alloy is increased, while the rate of the resist etching is decreased. As a result, the selection ratio to the resist can be made 2.5 or more. This is perhaps due to the reduction of BCl3. Thus, the selection ratio of the Al-Si-Cu alloy to the resist film can be improved, thereby assuring anisotropic etching in conformity with a pattern size without producing any residual copper.
