Inventor: YOSHII TAKESHI
IPC: G01N11/12
Filed: 1985-01-11
Abstract: PURPOSE:To measure easily the viscosity of sample liquid such as nasal mucus or phlegm by drawing the viscous liquid into a capillary, inserting a slender bar therein, erecting perpendicularly the bar and measuring the falling speed of the slender bar. CONSTITUTION:The viscous sample liquid 6 is drawn into the capillary 3 and one end of the capillary 3 is sealed by an extruding bar 7 in common use as an air lock. The slender bar 8 is put into the capillary 3 from the other one end and is dropped perpendicularly in the capillary 3, then the falling speed thereof is measured. The static viscosity of the viscous liquid is thereby measured. Since the viscosity is measured by dropping the slender bar into the sample, the easy measurement of the static viscosity is made possible and the viscosity of the nasal mucus or phlegm is correctly measured.

IPC: G01B11/00
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To enable wheel alignment measurement at high resolution and precision, while securing a wide measuring range. SOLUTION: Based on output signals DLD1-DLD4 of laser displacement meters 6-1-6-4, a calculation-process part 28 calculates a distance from a measuring surface of a measuring plate, and outputs a distance-measuring signal SY to a zoom focus control unit 29.

Title: Input/output log recording system
Inventor: AOKI YASUYUKI
IPC: G06F11/34
Filed: 1990-01-11
Abstract: PURPOSE:To reduce the overhead of software and to securely record log information by recording input/output log information by means of hardware, and recording a response code returned from an input/output device when an input/ output instruction is started. CONSTITUTION:At the time of starting an information processor, the minimum address 124 of a log area 123 is written in the address 121 of a main storage device 12' by the microprogram of a central processing unit 11'. When an instruction fetch part 111 fetches the subsequent instruction of software from the device 12', an instruction decoding part 112 decodes it. When the instruction is an input instruction, a counter 116 indicates the head address of an input/ output instruction routine (IR) in a memory 115' and IR is started. When the unit 11' receives the response code, it stores in an address which the register 114 indicates, increases a value which the register 114 indicates by one word, compares it with an address 125. When they are equal, the value of the address 124 is stored in the address 121. When they are not equal, the value of the register 114 is stored in the address 121.

Title: Displacement enlarging structure for piezoelectric actuator
Inventor: YAMAOKA FUMIYUKI
IPC: H01L41/09
Filed: 1987-01-07
Abstract: PURPOSE:To reduce the cost, and to improve the durability and the reliability of displacement enlarging structure for a piezoelectric actuator by attaching a plug sealed with operation liquid for converting the displacement of the actuator in the operating chamber of the actuator to remove a sealing structure, thereby simplifying the structure. CONSTITUTION:When a driving voltage is applied by a harness 12a to a piezoelectric actuator 12, an axial displacement occurs by an electrolysis induction strain in the actuator 12 to increase its whole length. This displacement causes an input side piston 15 to an operating chamber 19 to enhance the pressure of operation liquid 20 in a plug 21 to externally deform a recess sphere 21a, thereby axially displacing an output side piston 18 against the pressing force of a spring 22. The material 20 and the plug 21 are deformed by the depression of the piston 15, but do not change its volume due to noncompressibility. Thus, the displacement of the piston 15 is enlarged by the sectional area ratio of the cylinder 14 to the cylinder 17, and output as the displacement of the piston 18.

Title: Manufacture of flexible printed wiring board
Inventor: HARA KOJI
IPC: H05K3/00
Filed: 1990-01-09
Abstract: PURPOSE:To acquire a substrate which enables high precision wiring by forming a resist layer on an insulating layer for cover lay, by forming a soldering hole using ion etching and by removing the resist layer by plasma ashing thereafter. CONSTITUTION:A resist layer is formed on an insulating layer for cover lay and a soldering hole is formed by reactive ion etching. The etching is anisotropic etching having vertical direction property to the insulating layer for cover lay which is exposed from the resist layer; therefore, precision of pitch and hole diameter of a soldering hole can be improved without producing side etching. Thereafter, ashing gas is used instead of etching gas inside the same device and the resist layer is removed by plasma ashing. Thereby, a substrate can be acquired, which enables precision wiring.

Title: Power plant controller
Inventor: MURAO TERUO
IPC: G05B9/02
Filed: 1989-01-11
Abstract: PURPOSE:To prevent such a case where plural operation terminals are simultaneously disabled and to ensure the least necessary manual operations by setting a high function PI/O to each operation terminal serving as a least component element of a power plant and separating and connecting each PI/O from and to a control system independently of each other. CONSTITUTION:A back-up manual operation means 256 is contained in a high function PI/O 257. The PI/O 257 fetches the input process value to a CPU 2 via a PI/O bus 7 as long as the CPU 2 is normal. Then the PI/O 257 performs various arithmetic operations via the CPU 2 and outputs again an operation signal through an output circuit 4 via the bus 7. In the case the CPU 2 has a trouble, the operation terminal is manually controlled by the manual operation means 256 of the PI/O 257. Thus the necessary operation can be continued. As a result, the manual operations are carried out for each PI/O without using any hardware independent of a controller even in the case of CPU trouble.

Abstract: PURPOSE:To obtain a control of the blow-off air temperature immediately after the compressor is off in an air-mixing type air conditioning unit, by controlling the damper opening depending upon the air temperature after passing an evaporater, as well as a heater core. CONSTITUTION:A micro-computor 24 reads the data of a temperature setting unit 25 as well as sensors 26-30, computes the target blow-off air temperature Tt according to the numerical formula, and compares this Tt with the air temperature after passing a heater core Th. If Tt>Th, an air-mixing damper 21 is fully opened to obtain the maximum heating condition. If Tt<Th, Tt is compared with the air temperature Te after passing an evaporator. Then it Tt<Te, the damper 21 is competely closed to obtain the maximum cooling condition, while, if Tt>Te, the optimum air mixing ratio Mh is calculated according to the numerical formula in order to determine thereby the damper opening, which is output to an actuator 23. Accordingly, the blow-off air temperature variation can be controlled.
