Title: Ink jet recording device
Inventor: OHASHI TETSUHIRO
IPC: B41J2/185
Filed: 1995-03-31
Abstract: PURPOSE: To eliminate the necessity of a large ink tank and make a device smaller by providing a plurality of waste ink keeping means for keeping ink sucked by a suction means for sucking ink forcedly from an ink jet head and constituting at least one of them removably. CONSTITUTION: Negative pressure is generated in a cap pressed onto the surface of a recording head and a pump for sucking ink forcedly from a nozzle is provided, and waste ink discharged by the pump is introduced into the lower section of a removable waste ink tank absorber 11 through a pump connector 17 and an inlet connector 12 formed by melamine foam or the like. When the absorber 11 is in the full state, the state is sensed and informed to an user.

Title: Manufacture of photodetective element and photoelectric integrated circuit
Inventor: SHIKADA SHINICHI
IPC: H01L21/31
Filed: 1991-04-09
Abstract: PURPOSE:To provide a photodetective element small in dark current and excellent in characteristics such as sensitivity and the like. CONSTITUTION:The prescribed regions of semiconductor crystal layers 4, 6, and 8 formed of III-V compound semiconductor such as GaInAs or the like are removed for the formation of a mesa structure in a first process, where the crystal layer 6 serves as a light absorbing layer. The surfaces of the semiconductor layers 4, 6, and 8 exposed at the edge of the mesa structure are reconstituted with S or Se. Thereafter, an insulating film 10 is formed on the surfaces of the semiconductor layers 4, 6, and 8 through an ECR-CVD method. By this manufacturing method, many trapping centers are prevented from being formed on the surfaces of the semiconductor layers 4, 6, and 8. Furthermore, as the insulating film 10 is formed through an ECR-CVD method, the surfaces of the semiconductor layers 4, 6, and 8 can be covered with the insulating film 10 without deteriorating the surface treatment carried out with S or Se in effect. In result, a photodetective element small in dark current and excellent in characteristics can be obtained.

Title: Adapter equipped with timer
Inventor: ISHII HIROAKI
IPC: H02M7/06
Filed: 1993-03-10
Abstract: PURPOSE:To eliminate various troubles due to concentration on a game, e.g. TV game, for a long time by providing the power supply for the game machine, i.e., an AC-DC adapter, with a function for limiting the operating time. CONSTITUTION:A timer TC1 is built in a normal AC-DC adapter which transforms output from an AC power supply through a transformer T, rectifies the secondary voltage thereof through a rectifier Rec and then smoothes through a capacitor C to produce a DC power. When a set time is elapsed, a control signal from timer IC1 varies the base voltage of a transistor Tr to turn OFF the transistor Tr thus cutting DC output from an output terminal Eo. Consequently, a game machine employing such adapter equipped with a timer as a power supply stops operation to disable continuation of the game. A LED notifies elapse of set time by altering the color of emitted light or by flickering.

Title: Pressure controller of compressor
Inventor: SHIBATA EKIZOU
IPC: F04B49/06
Filed: 1978-06-26
Abstract: PURPOSE: To easily control a compressor, by decreasing the variation of pressure by adjusting the quantity of winds discharged from the compressor by signals obtained by comparison operating the command value of discharge pressure and discharge pressure in place of a pressure switch.  
     CONSTITUTION: When the pressure of a discharge air pipe 11 becomes lower than that of a pressure set instrument 1 during the operation of a compressor 10, signals from a pressure transducer 2 drop, and a PID controller 3 amplifies its negative deviation. When the value of the negative deviation becomes larger than that of a negative deviation set instrument 5, a negative deviation comparator 7 functions, the signals are input to an addition and subtraction computing element 8 and the number of capacity adjusting valves 9-1W4 that operate increases. Thus, the quantity of winds discharged from the compressor 10 augments, and the pressure of the discharge air pipe 11 rises up to set pressure. Consequently, the pressure of the compressor is modified so as to reach pressure shown in the pressure set instrument 1 centering around the value of the set instrument 1, and pressure discharged from the compressor can accurately be controlled.

Title: Image pickup device
Inventor: MIMOTO AKIHIRO
IPC: H04N5/225
Filed: 1985-04-12
Abstract: PURPOSE:To improve a line crawl and the SN ratio of a video signal without causing deterioration in phase characteristics by providing a means which extracts the contour signal of a video signal and inverts and controls its polarity, and mixes the output of it with the video signal. CONSTITUTION:The contour signal S4 is generated through a 1H (one horizontal scanning period) delay circuit 1 and a contour signal generating circuit 2 and the signal is level-adjusted by a contour signal processing circuit 3 and inputted to a polarity selecting circuit 5. The polarity selecting circuit 5 inputs a control signal Sc having a specific minus voltage previously and outputs a signal S6 obtained by inverting the polarity of the contour signal S4. For the purpose, the opposite-polarity contour signal S6 is added to the input video signal S1 and a video output signal S7 which is decreased in the white level at the front and rear end parts is sent out. A line crawl results from that a signal S8 having different brightness is inputted in every horizontal period and when this signal S8 is inputted, a mixing circuit 4 mixes a signal S9 from a polarity selecting circuit 5 with the signal S8 to output a video output signal S10, so the line crawl is reduced.

Abstract: PURPOSE:To prevent cross modulation between a video signal and an audio signal from being generated, by transmitting the video signal and the audio signal with carriers having the same frequencies and with linearly polarized light which intersect orthogonally with each other from different light transmission systems respectively. CONSTITUTION:At the light transmission systems 1 and 7 and the light reception systems 4 and 10 of transmission systems for the video signal and the audio signal, polarizing filters 3, 9, 5, and 11 are arranged at the front of modulation parts 2 and 8, and demodulation parts 6 and 12.

IPC: G02B6/12
Filed: 1988-03-30
Abstract: PURPOSE:To improve the control in a transverse direction by forming photoconductive parts on the ridges formed by dry etching of a crystal substrate plane by an MOCVD (organometallic chemical vapor deposition) method. CONSTITUTION:Grooves are worked on the <100> face of a GaAs substrate 1 by dry etching of RIE (reactive ion etching) to form the ridges. An AlxGa1-xAs layer 7, GaAs layers 8a, 8b, and an AlxGa1-xAs layer 9 are then successively laminated by the MOCVD method on the GaAs substrate 6. Crystal growth hardly takes place in 0-11 and 01-1 which are the wall surfaces of the grooves if the growth conditions of the MOCVD method are selected and, therefore, the crystal layers on the rides and the crystal layers on the grooves become discontinuous. The AlxGa1-xAs layers 7, 9 on the ridges function as clad layers and the GaAs layer 8b functions as the photoconductive layer constituting a boundary face with the air in the transverse direction. The light controllability in the transverse direction is thereby improved.
