Title: Injection molding device
Inventor: OZAKI YUKIO
IPC: B29C39/44
Filed: 1984-12-24
Abstract: PURPOSE:To make it possible to check the injection pressure with a simple device by arranging a pressure sensor in a piping section for supplying material. CONSTITUTION:A pressure sensor 12 is provided in the middle of a piping 5 for supplying material to which a signal processing display device 11 is connected. When material is injected from an injection nozzle 4 into a molding portion 3 and the material is injected completely in the molding portion 3 and an air reservoir 2, the pressure in the piping 5 is lifted up to the pressurized pressure in the material tank 8. The change of this pressure is measured by the pressure sensor 12 and signals from the sensor 12 are processed and displayed at the signal processing display device 11 to check the injection. Secure and complete checks can be done without applying special working to the mold 1 and affecting changing operation of the mold 1.

Title: Electromagnetically driven and half-opening shutter
Inventor: MATSUNAGA KAZUHIRO
IPC: G03B9/24
Filed: 1988-11-01
Abstract: PURPOSE:To perform a shuttering operation in high accuracy by turning a motor in a reverse direction to a diaphragm blade opening direction before the opening operation of the diaphragm blade is performed for a prescribed short time. CONSTITUTION:When photometric value is outputted from a photometric circuit 22, a control circuit 25, after calculating a standard pulse number Pn in response to the photometric value, sends a control signal for reversing a motor 1 to a motor driving circuit 26. Therefore, the motor 1 is reversed for a time Trev. When the motor 1 is reversed, the backlash and looseness of various gears, clutches, etc., are absorbed, and the mechanism of a power transmitting system is completely initialized. Thus, the blade opening motor 1 is reversed in a blade closing direction for a prescribed short time before a shutter opening operation is started, and looseness and initial errors before a shutter mechanism is started to operate can be eliminated. Thus, a half-opening shutter of high accuracy can be obtained without adding a special mechanism.

Abstract: PURPOSE:To enhance the cycle characteristic by preventing a hydrogen storage alloy from turning into fine powder through strengthening of the selective orientation of the alloy. CONSTITUTION:As a hydrogen storage alloy, a hexagonal crystal of CuCU5 type (AB5 type) can be named, where A component is La, Ce, Ca, etc., while B component is Cr, Mn, Al, etc. The maximum of P value is determined from the specified formula using the ratio of the integrated intensity I1(hkl) of the powder diffraction peak at the lattice plane (hkl) of the alloy to the integrated intensity I2 (h'k'l') of the powder X-ray diffraction peak at the lattice plane (h'k'l') selected arbitrarily as the reference surface and the ratio of the integrated intensity I3(hkl) of the X-ray diffraction peak at the lattice plane (hkl) of the alloy which is irregular in the crystal component direction to the integrated intensity I4(h'k'l') of the powder X-ray diffraction peak at the plane (h'k'l'). Expansive and contractive stress are applied to the crystal lattice of the alloy with occlusion and release of H2 at charging and discharging. In this AB5 type alloy, however, Pmax is over 20% to give a strong selective orientation, stresses are easily aligned in a certain fixed direction, collision of stress with one another is less likely, so that turning of hydrogen storage alloy into fine powder is likely to be generated.
