Title: Printing timing correction method in serial dot printer
Inventor: MAKI MASATAKE
IPC: B41J19/18
Filed: 1991-07-19
Abstract: PURPOSE:To improve the printing quality and to prevent the breakage of a printing head by a method wherein successive pulse-to-pulse time intervals for a fixed number of encode output pulses and the average value thereof are evaluated, and based on the difference between the both, a timing position of each encode output pulse is corrected. CONSTITUTION:A rising detection part 15 generates a rising pulse at the rising edge of an encode output pulse. A time interval detection part 16 measures intervals between the successive rising pulses. An average time interval detection part 17 takes the average of time intervals between rising pulses of a fixed number just before to find an average time interval as a reference. A comparing part 18 compares a time interval at every rising pulse with the average time interval. A variable delay part 19 adjusts a delay amount based on a time difference resulting from the comparison so that a time interval of successive rising pulses is equal to the average time interval. In this manner, a pulse train of a constant cycle outputted from the variable delay part 19 is used as a printing timing.

Abstract: PURPOSE:To permit a molding to be manufactured with a high degree of accuracy from a thermoplastic resin FRP and reduce consumption energy in association therewith by dividing a metal die into a small size metal die as 8 heating part small in heat capacity and a large size metal die as an accuracy retaining part large in heat capacity. CONSTITUTION:In a heating process I, the upper and lower metal die parts 3a and 3b in a large size metal die 3 are made to move apart in the opposite directions and a lifting device 5 is extended to separate the the large size metal die 3 and a small size metal die 1 from each other. After the molding material 6 of a thermoplastic resin FRP is then introduced into the small size metal die 1, the small size metal die l alone is heated by a heater 2 to melt the molding material 6 therein. In this heating process I, since the small size metal die 1 alone is heated, the heating time can be reduced. The next cooling process II is required of molding accuracy, since the molten molding material 6 in the small size metal, die 1 is cooled and hardened into a shaped article 7. To maintain the molding accuracy in this process II, therefore, the upper metal die part 1a in the small size metal die 1 is engaged with a recess part 4 of the upper metal die part 3a in the large size metal die 3.

A polycrystalline silicon thin film 12 is formed on the SiO2 layers 13 and on the seed sections 15 and is separated by side walls 18 of the SiO2 layers 12 into island regions. Utilizing a LOCOS-type wafer 14 thus constructed, Ge is deposited to form a Ge layer 16 on the single crystal silicon regions serving as the seed sections 15. By irradiation of linear electronic beams, the Ge layer 16 having a lower melting point that of Si is melted first and then Si is melted into the melt of Ge. Then, the Si melted region is extended gradually from on the seed sections 15 to on the SiO2 layers 13 and, finally, all of the polycrystalline Si thin film 12 is melted. Recrystallization proceeds from the substrate 11 to the polycrystalline silicon in and near the seed sections 15 and to the polycrystalline silicon on the SiO2 layers 13. Thus, the semiconductor can be single-crystallized smoothly.

Title: Motor protecting switch
Inventor: PEETAA HIRUFUIKARU
IPC: H01H73/56
Filed: 1983-09-28
Abstract: A rocking beam is movable into an "on" and an "off" position by actuating means which actuate linkage means and work against the force of a spring urging the beam into an intermediate trip-position. Through a guide surface the beam actuates a toggle assembly composed of two toggle levers linked by a toggle joint and having distal joints linked with a contact actuating lever and a pawl lever, respectively. When the pawl lever is restrained by the ratchet, the movement of the toggle joint caused by moving the actuating means into the "on" or "off" position results only in the opening and closing of contacts through a movement of their actuating lever. A readiness for switching on can be obtained by resetting the actuating means from the trip-position into the "off" position. If the switch is "on" and the pawl is released by the overload current trigger, then the spring can move the beam together with the actuating means into the intermediate, or trip, position, while a spring opens the contacts by operating the actuating lever. If the switch is released through the action of the short circuit trigger, then a toggle is also tripped and an external display becomes visible. It remains so until the toggle is reset by putting the actuating means into the "off" position. The switch can be reset by the same simple action.

Filed: 1992-07-07
Abstract: PURPOSE:To obtain a power factor controller which can always control receiving reactive power to zero by converting a reactive electric energy at a receiving point into a digital amount to perform a PI control, and converting its output to an analog amount. CONSTITUTION:A receiving reactive electric energy 12 is converted into a digital amount by an A/D converter 53, and a digital PI controller 51 outputs a generator exciting current increase command signal as a digital amount in response to amplitudes of its output and a receiving reactive electric energy set value Q (=0). This value is converted into an analog amount by a D/A converter 52, and output to an automatic voltage regulator 6. As a result, a generating delay reactive output amount 11 is varied, and a receiving delay reactive electric energy is reduced. Thus, the energy 12 of a receiving point is set to zero, and a power factor of the point is controlled to 1.0. That is, it is not necessary to provide a neutral zone for controlling ON/OFF as prior art by using the digital PI control.
