Title: Ink recoverer
Inventor: KOMAI HIROMICHI
IPC: B41J2/195
Filed: 1980-03-26
Abstract: PURPOSE:To detect the proper viscosity of ink by providing a viscosity detector to count the frequency of the natural dropping of the droplets of unnecessary ink from baffle plate to a gutter in the ink recoverer of a multinozzle ink head printer. CONSTITUTION:Ink droplets not participating in printing collide with a baffle plate 20, arrested there, and then drop from the lower end of the baffle plate 20 to a groove 21b. The dropping frequency of the ink droplets 25 is counted by a light emitter 24a and a light receiver 24b through the transparent parts 23a and 23b of both walls of the grooved member 21 in order to detect the viscosity of recovered ink. In this case, because such troubles as the reduction of the diameter of ink droplets due to drying and the intermixing of dust in the ink can be avoided, correct detected values can be obtained. During the starting or stopping time of the apparatus, the colliding face of the baffle plate 20 is cleaned by jetting a diluted ink from a nozzle 26.

Title: Still picture transmitter-receiver
Inventor: ARAKAWA HIROAKI
IPC: H04N7/12
Filed: 1987-02-20
Abstract: PURPOSE:To reduce the wasteful running of a disk memory by performing the input/output of a video signal for an external equipment or a transmission system, through a semiconductor memory, and transferring the video signal, as occasion demands, between this semiconductor memory and the disk memory. CONSTITUTION:The input/output of the video signal between the external equipment or another still picture transmitting receiving device, is performed by a processing for the semiconductor frame memory 24 as a write-in or a read-out to a semiconductor frame memory 24. Then, as occasion demands, the video signal is transferred between the semiconductor frame memory 24 and a floppy disk memory 26. Thus, the wasteful running of the disk memory 26 can be reduced, and besides, a restriction from the performance of the disk memory 26 can be reduced, and the various kinds of the processing of the video signal can be made easy.

Title: Bass-reflex type speaker system
Inventor: KATOU HARUMITSU
IPC: H04R1/28
Filed: 1981-03-16
Abstract: PURPOSE: To separate sound of a duct and a port from the sound of a front buffle plate by installing the duct and the board to a surface other than the front surface of the cabinet.  
     CONSTITUTION: In a speaker unit 1, a duct 5 and a port 6 are attached to a back board 4. Although it is the most preferable to attach the duct 5 and the port 6 to the back board 4, a fair effect can be expected by fitting them to the side board. Since the duct 5 and the port 6 are installed to the surface except a front buffle board 3, a sound radiated from a corn of the unit is prevented from being modulated by a sound radiated from the buffle board 3 and both the sounds are appropriately separated, reproducing sounds with fine S/N. Thus, the sound from the duct 5 and the port 6 are cleared and the load of an oscillation system is reduced, so that the generation of a standing wave is reduced and sounds of low frequency which can not be obtained by a closed type system is reproduced.

Abstract: PURPOSE:To improve the success rate of initial loading in retrial by driving a motor at speed different from the first one in the case of failing in the operation of drawing out the film from the cartridge and winding it round a spool. CONSTITUTION:An actuator driving part AC controls a motor M1 for prewinding and winding the film. In the case of the trial of initial loading, when the film is drawn out from the cartridge and the leading edge of the film is not detected by a photointerrupter PI even though specified time is up in a timer, the motor M1 is stopped and a register for counting the number of failures of the initial loading is incremented by one. Furthermore, the motor M1 is reversely rotated for the specified time and stopped. Thereafter, the initial loading is performed again by duty-controlling the motor M1 and intermittently feeding the film.

Title: Drive circuit of laser diode
Inventor: HONGO YOSHIYUKI
IPC: H01S5/042
Filed: 1991-03-05
Abstract: PURPOSE:To set a bias current to a high position and to obtain a proper extinction ratio by a method wherein, when the bias current at a laser diode exceeds a threshold value, a signal corresponding to their difference is added to an output signal from an automatic optical-output control circuit and an added signal is inputted to a drive circuit for light-emitting use. CONSTITUTION:Under operating surroundings in a room-temperature region, no output comes from a comparator 10, and a bias current and a light-emitting current are controlled so as to take a prescribed ratio by using an automatic optical-output control circuit 7. When the bias current is increased and exceeds a threshold value at a temperature or higher under the operating surroundings or in a deterioration mode, a light-emitting current control signal which corresponds to the difference between the bias current and the threshold value is added and input to a drive circuit 4 for light-emitting use, and the light- emitting current is increased. Then, the automatic optical-output control circuit 7 reduces the bias current by the increased portion of the light-emitting current. Thereby, the value of the bias current is controlled so as not to exceed the threshold value, and a proper extinction ratio is guaranteed.

Filed: 1979-03-30
Abstract: PURPOSE:To make small the size of refresh control circuit, by the burden of refresh processing by the processor with most priority of interruption of timer every given period. CONSTITUTION:The timer TIM counts the clock from the clock generator and produces the priority interruption signal NMI to CPU. When CPU receives it, it runs on the specified interruption routine of memory. Further, in the refresh routine TIR for timer interruption, the address register for refresh is cleared so that the refresh address can be the head address of the memory. Next, the address data is read in, which is indicated with the address register to execute the refresh. When the area of address finishes the refresh, the content of the register is added by +1, to point out the next refresh address location. Further, whether or not the renewed refresh address is within the area required for refresh processing is decided. Similarly, the program returns to normal state, after the end of refresh routine.

Title: Liquid heating and circulating device by use of steam
Inventor: ISHIDA YUKIO
IPC: F28C3/08
Filed: 1981-03-16
Abstract: PURPOSE:To adjust the liquid in a tank to have a uniform temperature distribution by a  method wherein in a silencer adopted to perform a heat exchange operation between the liquid  and steam by injecting the steam into the liquid, an annular steam film is blown into the liquid from an opening so that the liquid is heated and circulated forcibly in the tank. CONSTITUTION:The steam supplied into a steam chamber 3 through a supply pipe 6 is compressed as it comes close to an opening 4 and injected into a liquid communication cylinder 2  from the opening 4 at a high velocity and in the form of the thin annular steam film 7 so that  pressure is applied on the part of the liquid in front of the opening 4 and then the steam film  is blown from an opening (b) of the cylinder 2 as it is accompanied with the part of the liquid which has filled the cylinder 2. The steam film 7 is the liquid flows toward the opposing wall  of the lower part of the tank 1 and then moves upward along the wall. At the same time, a  strong sucking force generates at an opening (a) of the liquid communication cylinder 2 due to  the blowing off of the liquid outside the cylinder 2 by the steam film 7 so that the lower part  of the liquid is sucked in and therefore, a liquid flow from the upper part of the tank 1 down  to the lower part thereof generates behind the cylinder 2 to make the entire liquid circulate  through the tank 1. As a consequence, the liquid can be heated efficiently by mere injection of  the steam film into the liquid communication cylinder 2 and further, as the liquid circulates  through the tank 1, it can be heated uniformly.
