Title: Current meter
Inventor: KABEUCHI TERUO
IPC: G01F1/34
Filed: 1988-12-13
Abstract: PURPOSE:To enable employment of a current meter without being restricted by the concentration of particles by a method wherein a shielding means to shield an optical path in accordance with a fluid pressure is provided on the optical path of each optical fiber. CONSTITUTION:On the occasion of detecting a flow velocity, a shielding means 7A receives the pressure of a fluid proceeding onto the downstream side of the direction of a flow, while a shielding means 7B receives the pressure of a fluid proceeding onto the upstream side of the direction of the flow. The fluid pressure applied to the means 7A is the sum of a static pressure and a dynamic pressure, while the fluid pressure applied to the means 7B is the static pressure alone. Therefore the degree of interception of the optical path of an optical fiber 6A by the means 7A is larger than the degree of interception of the optical path by the means 7B. The propagation efficiency of the fiber 6A for which the means 7A is provided is lower than the propagation efficiency of the fiber 6B for which the means 7B is provided, and in a light-sensing means, the quantity of light received by the fiber 6A is smaller than that of light received by the fiber 6B. Accordingly, when the quantity of light decreased in the fiber 6A is denoted by A and the quantity of light decreased in the fiber 6B by B, the direction of the flow can be detected by detecting the polarity of (A -B)/(A + B), and the velocity of the flow can be computed by determining the absolute value of the above.

Abstract: PROBLEM TO BE SOLVED: To break a switch by quickly returning a time setting operation shaft to the origin when a temperature abnormally rises by excessive time setting or midway stopping by failure or the like in a time switch used in an oven toaster or the like. SOLUTION: For example, a gear 3c is installed on a rotary shaft 3a of a third wheel so as to be relatively rotatable, and a heat clutch 25 is installed so as to be relatively nonrotatable, respectively. Rotational torque of these heat clutch 25 and gear 3c is transmitted by engagement between an engaging part 25a and an engaging hole 3h or frictional contact having no engaging structure, and when an abnormal temperature rise is caused, the heat clutch 25 is thermally deformed in the direction for separating from the gear 3c, and relative rotation of the heat clutch 25 (a rotary shaft 3a) and the gear 3c becomes possible. Therefore, a time setting operation shaft can quickly return to an original position by accompanying rotation of the rotary shaft 3a separated from the gear 3c.  According to such as plate-shaped heat clutch 25, even if a safety mechanism is added, a structure can be simply and compactly constituted.

Title: Semiconductor non-volatile memory
Inventor: YOSHIDA KEIICHI
IPC: G11C16/02
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To simplify a control circuit by utilizing a microprogram ROM having a series of command train in which a command for executing a series of operation sequences is stored and the circuit sequence to conduct the similar operations is registered as the subroutine. SOLUTION: When a series of operation sequence includes the 15 operations in total in combination of commands COM0 to COM6, when the command corresponding to the operation sequence is stored in the microprogram ROM, namely μ-ROM, 15 addresses of the μ-ROM corresponding to 00H to 0EH are required corresponding to the number of operations. Combination of commands executed in the same sequence is extracted from such 15 operations as the subroutine and the commands COM1 to COM4 are used repeatedly. Thereby, the address of μ-ROM can be reduced to 11 addresses 0DH to 0AH. As a result, the area of μ-ROM including much repeated operations of the operation sequence can be reduced.
