Title: Optical position detector
Inventor: KOIDE SATORU
IPC: G09G1/00
Filed: 1985-04-09
Abstract: PURPOSE:To prevent detection error even with thick electron beam by synchronizing the scanning period in H and V directions with a photodetection signal and obtaining an object position on a picture display screen from the time ratio with the scanning period. CONSTITUTION:One H direction scanning line for picture display is increased to generate a lighting signal in the X axis direction. On the other hand, the lighting signal in the Y axis adjusts the deflection circuit that the scanning line in the H direction is spread from an effective picture display screen 16 and a fluorescent screen 7 in the inner face of the side wall in the (y) direction is scanned. Thus, the same number of the lighting signal 52 having a lighting time tH as the H direction scanning line is generated in a time tV as shown in figure in the (y) axis direction. A position detection control section detects the position in the (y) axis from a point where a ray is shut by an object point 15 on the picture display screen in synchronizing with the lighting signal 52 as shown in figure in the (y) axis direction and the photodetection signal is missing and calculates the position in the X axis from the ratio of photodetection signal missing time tF to lighting time tH in synchronizing with the lighting signal 51.

Title: Stamping molding method and stamping mold
Inventor: SEKINE MASAKAZU
IPC: B29C45/00
Filed: 1995-03-30
Abstract: PURPOSE: To prevent the damage of a skin and to effectively prevent the shrink of a thick part such as a gate. CONSTITUTION: After an upper mold 2 and a lower mold 1 are clamped, gas is poured from the vicinity of a hot runner gate 12 in a formed molding 4 before cooling. A gate is energized by the pressure of the gas in an opposite direction to shrinkage, thereby preventing a sink. Since the shrinkage in the thickness direction is absorbed by the increase in the volume of a cavity 40 due to the present part of the cavity 40 formed of the charged gas, the sink is further prevented. Since it is not necessary to increase a mold clamping pressure, the damage of a skin 3 is prevented as well.
