Title: Electrostatic printer and methods for supplying developer and mixing powder
Inventor: SHIMOKAWABE IKUO
IPC: B01F13/00
Filed: 1989-03-18
Abstract: PURPOSE:To mix developer uniformly and to prolong service life by creating a relative velocity between the toner and carriers in a channel for the developer containing the unmixed toner and carriers, and mixing both. CONSTITUTION:In the channel for the developer containing the unmixed toner 12 and carriers 13, both are mixed after creating the relative velocity between them. An electrostatic printer is provided with a highly effective hole 11 for restraining the movement of lightweight microtoner 12 in the flowing direction, by utilizing the fact that they have significantly different surface energies because of differences in specific gravity and grain diameter; by passing powder drain, composed of the carries 13 and toner 12, through the hole 11, the relative velocity is created between them, and both are mixed. Thus, the toner can be uniformly dispersed in the carriers in a short time, and stabilized for a long time.

Filed: 1990-03-16
Abstract: PURPOSE:To facilitate the removal of spuriousness, etc., from a nonlinear element by obtaining a microwave band local oscillation signal for transmission and reception, a local oscillation signal for phase detection at the time of reception, and repetitive pulses for repetitive transmission by one oscillator. CONSTITUTION:The microwave band local oscillation signal F1 for transmission and reception, the local oscillation signal F2 at the time of reception, a reference signal F4, and the repetitive pulses Po for repetitive transmission are generated by using one oscillator 10 as an oscillation source. Then the outputs of the respective signals are set to integral multiples of the pulses Po which are generated by multiplying the output of the oscillator through multipliers 11, 15, and 28 and dividing the frequency of the output of the oscillator 10 by a frequency divider 25. Therefore, the spuriousness generated in a Doppler area owing to the nonlinear factor or a noise spectrum induced with a large-electric-power pulse is superposed upon the spectrum of a sent wave and removed by MTI processing, so that an image and a Doppler sound which are obtained become articulate.

Title: Processing method for interruption of computer
Inventor: KATO YUKIO
IPC: G06F13/24
Filed: 1987-03-24
Abstract: PURPOSE:To reduce hardware in size and cost by performing the interruption processing on the inside of a CPU without providing an interruption signal holding circuit on the outside of the CPU. CONSTITUTION:An interruption signal A is supplied to an interruption pin and an input-1 pin of a CPU 4. The CPU 4 is shifted to an interruption processing routine from a main routine with input of the signal A and then inhibits the subsequent interruptions to carry out the interruption processing. When this interruption processing is over, the CPU 4 is reset to the main routine. In this case, however, an interruption inhibiting state is not released. Instead a fact that the signal A is not active is confirmed and an interruption permitted by an interruption signal sense routine that is carried out in the intervals of the normal processing in the main routine. In such a permission >=2 times interruption are prevented by the same interruption signal. As a result, an interruption signal holding circuit set on the outside of the CPU can be omitted for reduction of the hardware in size and cost.

Title: Manufacture of paste cadmium plate
Inventor: NISHIKAWA KOJI
IPC: H01M4/20
Filed: 1989-03-20
Abstract: PURPOSE:To aim at a remarkable improvement in performance by coating a conductive core with active paste incorporating cadmium oxide or the like and zinc to thus manufacture a plate, and charging the plate in such a state as to be immersed in an alkaline solution so as to convert a part of cadmium oxide into metallic cadmium by a chemical conversion treatment. CONSTITUTION:A conductive core is coated with active paste incorporating cadmium oxide or cadmium hydroxide and zinc, thereby manufacturing a plate. The plate is charged in such a state as to be immersed in an alkaline solution. As a result, the shape of the active material is changed by charging so that a zinc-solved liquid is easy to be dispersed in the plate. Therefore, a zinc reducing reaction is expedited, and then, zinc hydroxide solved in the alkaline solution can be produced. Since the zinc hydroxide as a reaction product can be easily removed by washing with water or the like, zinc can be restrained from remaining in a negative plate. Consequently, conductivity of an electrolyte is not reduced so that a decrease in operating voltage can be prevented at the time of discharging of a battery. Furthermore, priority of the negative plate can be prevented at the time of charging/discharging of the battery.
