Title: Hand indication type electronic clock
Inventor: SUGANO FUMIO
IPC: G04C3/14
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To prevent a clock from stopping shortly owing to brief interception of light after a hand position is corrected, by a method wherein a voltage at which a hand starts to move, driven by a specific modulated drive pulse, is set to be higher than the voltage of another modulated drive pulse. SOLUTION: A battery of a power source 49 stores the light energy entering a solar cell, as a voltage. In a state wherein the voltage of the power source 49 is sufficient, a rotor 34 is driven by a normal drive pulse emitted every one second. In the case when the voltage of the power source 49 becomes a prescribed one or below, a quick feed at every two seconds, i.e., a drive by a first modulated drive pulse, is conducted so as to urge an user to expose a clock to the light. In the case when the voltage of the power source 49 lowers further and it becomes impossible for the rotor 34 to rotate normally, the drive is conducted by a second modulated drive pulse having a narrower pulse width than the first modulated drive pulse. A starting voltage of the rotor 34 by the second modulated drive pulse is higher than the one by the first modulated drive pulse.  Therefore the rotor 34 rotates normally and the clock does not stop even when it is not exposed to the light for some time thereafter.

Filed: 1986-11-14
Abstract: PURPOSE:To make it possible to form a gettering layer without the remnant of a contamination source of a wafer, by jetting ice particles, forming lattice defects on the rear surface of a semiconductor wafer, and introducing impurities in the entire surface by an impurity introducing method such as an ion implantation. CONSTITUTION:Lattice defects as a gettering layer are introduced in the rear surface of a semiconductor wafer 13 by using an ice making device 12. For this purpose, ice particles 8 are jetted from a blasting device 11 of the ice making device 12 so that the particles hit the rear surface of the semiconductor wafer 13, to yield the lattice defects. Thereafter, semiconductor impurities of group III-V and VIII elements or compounds and the like including said elements are introduced in the rear surface of the semiconductor wafer 13. Thus a gettering layer 14 is effectively formed as a lattice deffect layer. When the semiconductor impurities are introduced, not only the ion implanting method but also ordinary impurity introducing methods such as a diffusing method can be used. Thus a high gettering effect can be obtained, and contamination problems can be solved.

Title: Control damper of room air volume displacement under positive pressure
Inventor: YAMASHITA TERUMI
IPC: F24F13/15
Filed: 1984-12-26
Abstract: PURPOSE:To keep the room air at positive pressure even at the start of an exhaust fan and consequently prevent the cleanness in a clean room from lowering by a method wherein the rise characteristic of the exhaust fan is checked not more than that of the supply air. CONSTITUTION:When an exhaust fan is started, the outside air is sucked from the opening 17 of an auxiliary damper 16, because a main damper 19 is in the fully closed state and the auxiliary damper 15 is in the fully open state at the start of the exhaust fan. After that, the difference between the pressures before and after the main damper 19 is generated, resulting in starting to rotate the upper part of the main damper 19 toward the suction port of the fan, because a shaft 20 locates at a position lower than the center of the main damper 19. However, in this case, the main damper 19 is not allowed to open quickly due to a spring 21 attached at the upper end of the main damper 19 and to the resistance of a shock absorber 22. The auxiliary damper 16 is closed by a link mechanism in the reverse action of the gradual opening of the main damper 19.

Title: Screw for injection molding machine
Inventor: NAKAJIMA HIDEAKI
IPC: B29C48/59
Filed: 1993-10-05
Abstract: PURPOSE:To shorten a staying time of a molding material in a heating cylinder without impairing an effective ejection amount and a scuffing preventing function per one revolution. CONSTITUTION:A screw 1 has a screw groove 3 of substantially the same pitch P and its groove depth is gradually reduced in depth from a supply unit to a metering unit similarly to a conventional screw, and the flight width F of a flight 2 is set to a range of 0.3 to 0.5 times as large as the diameter D of the screw 1. Thus, although a depth of the groove 3 is of a size equivalent to that of a conventional screw, a staying amount of a molding material in a heating cylinder decreases and hence the staying time is shortened. Accordingly, a heat history scarcely affects the screw, and discoloring, decomposition of the material can be prevented.
