Title: Method and equipment for injecting liquid into wood
Inventor: IKEGAMI KUNINOBU
IPC: B27K3/08
Filed: 1989-10-20
Abstract: PURPOSE:To obtain excellent liquid-injecting effect and moreover to cause its number of treating processes to be reduced by a method in which after the pressure in a tank has been reduced, while the inside of the tank is pressurized by feeding liquid into the tank with a pressurizing pump, the retained air existing on the surface of the wood to be treated is discharged outside of the tank and simultaneously the liquid is injected into the wood. CONSTITUTION:A suitable number of timbers to be treated are put on a carriage 3, and the timbers 2 to be treated are fixed there. The carriage 3 is received in a pressure vessel 1 by using a carriage 31 and a rail 15, and the vessel is closed with a cover 9. In this state, treating liquid 20 is injected into the pressure vessel 1. The treating liquid is sent therein to the extent such that the timbers to be treated do not appear on the surface of the liquid. Next, a pressure device 6 is operated, a pressure-reducing device 4 is operated, and the pressure in the pressure vessel 1 is reduced to at most 160Torr through the upper pressure-reducing nozzle 10 of the pressure vessel 1, and then the pressure-reducing degree in the pressure vessel 1 reaches upper limit and the pressure-reducing degree in the pressure vessel 1 becomes equal to that in a gas liquid-separating device 16. Then the treating liquid collected in the gas liquid-separating device 16 is restored in the pressure vessel 1 through a valve 17.

Title: Ion-implantation device
Inventor: FUJII HARUHISA
IPC: H01J37/317
Filed: 1989-10-20
Abstract: PURPOSE:To make it possible to finish an ion-implantation without using an electronic shower at the time of an ion implantation or to make it possible to make small the load of the washer even if the washer is used by a method wherein a saw-toothed groove is provided in the surface of a rotating disc, on which a wafer is fixed, to increase the amount of secondary electrons from the disc and to inhibit efficiently an electrification of the wafer. CONSTITUTION:In an ion-implantation device, a saw-toothed groove 12 is provided in the surface of a rotating disc 1, on which a wafer 9 is fixed when an ion- implantation is performed, whereby the generation amount of secondary electrons 11 from the disc 1 is increased and an electrification of the layer 9 is efficiently inhibited. For example, a saw-toothed groove 12 having a depth of 1.0mm and an angle of inclination of 45 deg. to a wafer of a thickness of 0.5mm is formed in the peripheral part of the wafer 9 on a rotating disc 1 in the form of a concentric circle to the center of the wafer 9. Thereby, an ion beam 10 irradiated on the disc 1 emits secondary electrons 11 according to its energy, but the generation rate of the secondary electrons is high if a surface to be irradiated is slanted, positive ions themselves which collided against the inclined surface are reflected, again collide against the inclined surface and the probability of the emission of the electrons 11 is increased.

Title: Image pickup device
Inventor: HASHIMOTO SEIJI
IPC: H04N5/335
Filed: 1984-12-28
Abstract: PURPOSE:To reduce occurrences of pseudo-signals to form a high grade frame picture by forming a picture signal for one frame which allows a vertical correlation distance of information to approach to a reading out of picture information accumulated in a pickup element (SIT) where a non-destructive reading is possible. CONSTITUTION:In the case of still picture pickup, an unnecessary charge accumulated in a whole image pickup cell is reset simultaneously to control an accumulated hour of charge after shutting a shutter at a prescribed time later. After then, from an SIT2, as n1H and n2H... are read out in turn, odd number field picture signals are formed and as m1H and m2H... are read out in turn, even number field picture signals are formed to obtain the picture signal for one frame. Furthermore, in the case of a moving picture pickup, the reset is performed after reading out a signal and the accumulated hours of charge are decided by a timing of reading out a following signal. For instance, after completion of reading out n2H signal when two resets of horizontal line l2 and l3 are carried out, the accumulated hours for horizontal line l2 and l3 at the time of reading out m1H become equal to eliminate a level difference of signals.

Filed: 1984-12-28
Abstract: PURPOSE:To eliminate a pulsating torque of a rotor by varying the disposition (phase) of teeth formed in one salient pole, and operating the harmonic wave of the torque at the teeth in different phases. CONSTITUTION:The number of teeth formed on the salient pole 11 of a stator 1 is set, for example, to 4, the phase displacement of P/4 is provided between the first and second teeth and between the third and fourth teeth with the pitch P of the teeth of a rotor 2 as a reference, thereby forming two pairs.

The third and fourth teeth become similar therebetween to cancel the secondary torques in the pairs. Thus, 2 teeth pairs of the phase displacement of P/4 are used as base, and are disposed with further displacement of P/6. Then, the second and third harmonic waves can be canceled to approach the torque characteristic to sinusoidal wave.

Title: Odd-even discrimination circuit
Inventor: IWATA HIDEO
IPC: H04N7/00
Filed: 1985-12-10
Abstract: PURPOSE:To discriminate whether a field is of an odd number or even number with a simple constitution, by providing a retrigger multivibrator circuit, counter circuit, and latch circuit and supplying composite synchronizing signals to the input terminal of the multivibrator circuit. CONSTITUTION:Waveforms of a composite synchronizing signal input terminal 10 during a vertical blanking interval are shown in Figs. (a) and (h). If the time constant of a retrigger multivibrator circuit 3 is set a little longer than the time intervals of equalizing pulses and a little shorter than the time intervals of horizontal synchronizing pulses, output waveforms becomes the ones shown in Figs. (d) and (e) and (k) and (l). When clock inputs are (b) and (i), clear inputs are (c) and (j), and gate signals are (d) and (k), the output signal QA of a counter circuit 4 goes to the ones shown in Figs. (f) and (m). Therefore, the clock input and data input of a latch circuit 5 respectively become those shown in Figs. (e) and (l) and (f) and (m) and, as a result, waveforms of and output signal 53 become those shown in Figs. (g) and (n). Accordingly, when the output of an odd-even discriminating signal output terminal is checked, odd fields from 10H to 271H become '0' and even fields from 272H to 9H goes to '1'. Thus whether a field is of an odd number or even number can be discriminated.
