Title: Diaphragm for speaker
Inventor: SAEKI MICHIZOU
IPC: C22C23/00
Filed: 1981-04-16
Abstract: PURPOSE:To obtain a diaphragm for speaker having a less secular change by using the Mg-Zr alloy containing 0.2-1.0% Zr. CONSTITUTION:A diaphragm made of only Mg deteriorates owing to a secular change in characteristics due to the recrystallization temperature of Mg. When Mg- Zr alloy having an additive of 0.2-1% Zr is used, the deterioration of stiffness is suppressed to some extent where there is no trouble in practical use even if the heating of a diaphragm due to the generation of the heat of a voice coil in driving a speaker and the repetition of annealing due to natural cooling when the diaphragm is not oscillated. Therefore, the lowering of the limit frequency of high sound intensity reproduction is specially suppressed to maintain the quality when it is set.

Title: Injection molding machine and injection molding method
Inventor: MIYAZAKI TATSUYOSHI
IPC: B22D17/20
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To attain quick and high quality injection molding without largely retreating molten metal from a nozzle position by fitting a nonreturn valve in the position of a plunger and opening the die after injection molding. SOLUTION: The piston 20 is pushed down and the molten metal is injected into the die 16 through an injecting course 15. After injecting, the piston 20 is ascended in the cylinder part 18 under condition of non-opening the die 16. By this method, the inner part in a cylinder 18 becomes the condition of negative pressure and thereafter, when a communicating hole 32 coincides with the through-hole 22 of the cylinder part 18, the molten metal is poured into the cylinder 18 through the through-hole 22, communicating hole 32 and the nonreturn valve 34. Thereafter, when the injected molten metal cools, the die 16 is opened to take out the molding.  The flowing passage of the molten metal at the time of injecting the molten metal into the die 16 by working the nonreturn valve 34 in the piston 20 can extremely be shortened and the circumferential air is not entrapped at the time of injecting the molten metal, and since the injecting course to the die 16 is short, the injection time is shortened.

Title: Picture image forming device
Inventor: YOSHIMOTO TOSHIO
IPC: B65H7/04
Filed: 1985-03-25
Abstract: PURPOSE:To prevent possible jamming from occurring by providing a carrying control means so as to delay the detection of recording paper within an intermediate paper feeding/discharging means until the recording paper which has been fed into the intermediate paper feeding/discharging means, arrives at a paper feeding point. CONSTITUTION:When a printer receives information on a picture image from an outside device 5, data for the required mode selection is determined by a carrying control means 6, then, a paper feed command is directed to a paper feeding means 1 so as to feed recording paper of the required size from numbers of paper feeding sections. Subsequently, the picture image is formed in order at a picture image forming section on the recording paper which is fed at regular time intervals. And a command is directed to a carrying condition detecting means 4 from the carrying control means 6 so as to delay the detection of the recording paper until the recording paper which has been discharged to an intermediate paper feeding/discharging means 3, arrives at a paper feeding point. No halt instruction is directed before the recording paper arrives at the feeding point. This allows the paper to be properly carried into the feeding point. This configuration prevents possible jamming on the carrying way of the recording medium from occurring so as to carry the recording medium properly.

Only three sensors are shown in this drawing aut a necessary number of the sensors are actually arranged at the heights corresponding to the desired flow rates of a perfusate. The sensors can he freely changed in a height. A stepping pedal 4 performs the start/stop of suction. The start signal thereof enters a controller 6 and selects a suction pressure value according to a program to give indication to a suction device 9. At the same time, the sensor provided at the height corresponding to said value is allowed to function. When the cylinder reaches this position, the sensor sends a signal to the controller.
