Title: Field effect type liquid crystal display panel
Inventor: MATSUO YOSHIHIRO
IPC: G02F1/1343
Filed: 1986-09-08
Abstract: PURPOSE:To prevent the generation of an abnormal display phenomenon by forming a dielectric layer having an electric insulating resistance value included within a range smaller than a resistance value of liquid crystal on the surface of an electrode in a field effect type liquid crystal display panel. CONSTITUTION:Resistance RD per unit area of the dielectric layer is smaller than resistance RL per unit area of a liquid crystal layer. Under the condition of RD<<RL, external DC voltage VD to be supplied reaches impression voltage VL originally required for the liquid crystal layer, and when RD is sufficiently small as compared to the RL, VD is almost equal to the VL and load to driving circuit parts can be reduced. Under the condition of RD<<RL, the DC voltage VD applied to the dielectric layer can be sufficiently reduced as if it can be neglected as compared to the VL. Consequently, various abnormal display phenomena due to the dielectric layer can be reduced as if they are neglected or completely removed.

Title: Radiation measuring instrument
Inventor: TOMIZAWA MASAMI
IPC: G01B15/02
Filed: 1985-09-26
Abstract: PURPOSE:To measure a radiation dose previously with a wide dynamic range by varying an integration time according to the level of a radiation detection output signal. CONSTITUTION:The output signal of a radiation detector 7 is integrated by an integrator 13, whose integral value is compared with a reference voltage V0 by a comparator 15. A counter 23 begins to count clock pulses from a reference clock generating part 17 on the start of the integration of the integrator 13 and an AND gate 21 is closed when the integral value reaches the V0, thereby stopping the counting operation. Count data is sent to an arithmetic control part to perform reciprocal arithmetic, finding the radiation dose. If the detection output of a detector 7 is small and the counter 23 overflows before the integral value reaches the reference value V0, a signal S5 is outputted through an FF 25, etc., to turn OFF the switch 13e of the integrator 13, so that the time up to when the integral value reaches the reference value V0 varies. Thus, the radiation dose is measured precisely with the wide dynamic range.

Abstract: PROBLEM TO BE SOLVED: To avoid excessive design of a coating layer formed by spraying. SOLUTION: A spraying device is provided with a fine powder feeder 10, a flash-setting agent feeder 12 and a spraying pipe 14. A main component A, an oxidizer C and a hardening accelerator D are sent from the feeder 10 to the pipe 14, conveyed toward the tip side of the pipe 14 and mixed with an adhesive component in the vicinity of nozzle 23 to produce a flash-setting compsn. In a process for hardening the compsn., the main component A becomes the nucleus of a hardened body. In a formed coating layer, polytacrylate salt or polymethacrylate salt is interposed among dispersed active fine particles to become a form where the active fine particles are stuck by these materials. After the formation of the coating layer, the main component A consisting of blast furnace slag and fly ash produces a hardened body.  The hardening accelerator D accelerates the hardening of the main component A and the strength of the coating layer can be regulated in accordance with the added amt. of the accelerator D. After about 2N/mm<2> compressive strength is exhibited at 10 min of age, the strength can be increased up to about several times for long term.

CONSTITUTION:Such a plated base layer 2 as a film consisting of a catalyst for plating, a film consisting of a catalyst compound for plating, a metal film or the like is formed on the surface of an insulating base material 1.
