Filed: 1982-07-19
Abstract: PURPOSE:To enable liq. crystal display of high quality by applying a composition contg. specified polyamic acid to the liq. crystal sides of substrates each having a transparent electrode film, and causing the ring closure of the polyamic acid by dehydration to form polyimide films. CONSTITUTION:Biphenyltetracarboxylic acid anhydride is brought into reaction with diamine such as m-phenylenediamine in a solvent to produce polyamic acid. The resulting composition contg. polyamic acid is applied to the liq. crystal sides of substrates each having a transparent electrode film, and by heating the substrates, the ring closure of the polyamic acid is caused by dehydration to form polyimide films. Thus, the desired substrates for holding a liq. crystal are obtd. The polyimide films used as orienting films are slightly colored, and they have superior adhesive properties to the substrates and superior orientation controlling power for keeping a liq. crystal in a homogeneously oriented state. The orientation controlling power is not deprived by heat treatment.

Abstract: PURPOSE:To find the incident direction of a low-frequency sound in real time by detecting the magnitude of vibration with a strain gage, sending it to a BPF, finding a ratio of primary mode signal to secondary mode signal with a divider, and sensing it to an incident angle computing element. CONSTITUTION:When a sound wave from a sound source (a) is received with rectangular plates 2a, 2b, the plates 2a, 2b are vibrated. Such vibration are detected with the strain gages 3a, 3b, and furthermore, the signals of primary and secondary modes are band-passed by the BPFs 5a, 5b for primary mode detection and the BPFs 6a, 6b for secondary mode detection, and are sent to the dividers 7a, 7b. A quantity decided only by an incident angle can be decided in spite of the level of sound by taking the ratio of primary mode to secondary mode. Therefore, the ratio of primary mode signal to secondary mode signal can be found at the dividers 7a, 7b, and they are sent to the incident angle computing element 8, and the computing element 8 calculates and outputs the incident angle of the sound for the plates 2a, 3b. In such a way, the incident angle of the sound wave from the sound source (a) can be easily obtained.

Title: Coil for transformer
Inventor: YAMANAKA KOUJI
IPC: H01F27/32
Filed: 1983-07-15
Abstract: PURPOSE:To obtain a coil for a transformer having excellent dielectric strength by forming a clearance between sheet-shaped electric wires. CONSTITUTION:Sheet-shaped electric wires 1 and inter-layer insulating materials 4 wider than the width of electric wires inserted among the electric wires 1 are wound spirally to form a coil. For form clearances 3, the both end sections of the inter-layer insulating materials 4 are folded back, and the tip sections of the sheet-shaped electric wires are placed on the folded-back sections. Consequently, conductive foreign matters mixing among the sheet-shaped electric wires do not damage the inter-layer insulating materials 4 because of the clearances. The insulating materials of sections, which are in contact with the burrs of the tip sections of the sheet-shaped electric wires, are reinforced to the burrs. Accordingly, dielectric strength can be increased without inserting another insulating material by folding back the both ends of the inter-layer insulating materials. When the number of fold-back is increased, the clearances augment, and the dielectric strength increases only by a section corresponding to the augmentation of the clearances.
