Title: Converter for hydraulic mechanism
Inventor: IMAMURA YUUZOU
IPC: F15B11/20
Filed: 1980-11-06
Abstract: PURPOSE: To efficiently drive an engine with pressurized oil, by introducing pressurized oil pressurized through a pressure accumulator, into a cylinder having a piston slidably fitted therein, through an oil distributor and an injection pump.  
     CONSTITUTION: When a brake pedal is slightly pressed at the time of starting, a switch is turned on in connection with the brake pedal to drive an injection  pump 6 by the power of a battery 5. As a result, oil in an oil vessel 3 is supplied into a pressure accumulator 1 through an injection port 7 to compress a  spring 8 to accumulate pressure. Oil is also supplied to the pressurized oil receiver 17 of an oil distributor 2 through an oil pipe 15 to fill the receiver with  the oil. At that time, a gear 18 is rotated by a starting motor to rotate an oil  valve 20 through a gear 19 so that the oil in the pressurized oil receiver 17 is  distributed to cylinders 25 through a pressurized oil pipe 29 to reciprocate  pistons in prescribed order. An engine is thus driven.

Title: Speaker
Inventor: SAEKI MICHIZOU
IPC: H04R7/18
Filed: 1983-08-26
Abstract: PURPOSE:To improve the input capability by using an aromatic polyimide resin to which boron nitride powder having an excellent heat conductivity is mixed at least for a support member to improve the heat conductive characteristic. CONSTITUTION:An aromatic polyimide resin film mixed with the boron nitride powder having excellent heat conductivity is used at least for the support member of the diaphragm. Since an edge 10 has a good heat conductivity, the radiated heat from a voice coil 7 and the conducted heat form a coil bobboin 6 are conducted in excellent way, the heat is dissipated to a front plate 2 via a support 9, thereby suppressing temperature rise of the voice coil 7. Thus, a larger input signal is impressed to the speaker in comparison with a speaker using a conventional edge thereby improving the input capability of the speaker.

Title: Liquid developing device
Inventor: WATANABE MITSUYOSHI
IPC: G03G15/10
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To form a high resolution image reduced in fogging and surface staining by making the sweepback contact angle of a liquid developer in a non-latent-image part larger than that in a latent image part, on the surface of an image carrier. SOLUTION: As a photoconductor material used for a photoreceptor drum 2, an organic photoreceptor normally called OPC is used and the sweepback contact angle of the liquid developer with the surface of the drum 2 is adjusted to set a wetting property. At this time, the sweepback contact angles α and βin the electrostatic latent image and non-electrostatic-latent-image parts on the surface of the drum 2 are set to satisfy the relation of β>α. The sweepback contact angle is one measured after a part of a stuck droplet is quietly removed by an injector, etc. As the sweepback contact angle is larger, the removal of the droplet is easier and a residual droplet can be reduced. Thus, on the drum 2, the liquid developer is easily peeled in the non-latent-image part and stickability is enhanced in the latent image part.

Abstract: PROBLEM TO BE SOLVED: To judge whether an air bag can be initiated or not without man's operation by detecting the presence of a person and a child seat by a distance measuring means and comparing it with a reference detection value of the distance measuring means for a vacant seat in advance to detect a seated condition. SOLUTION: When a seat is vacant and data obtained by measuring by a distance measuring means 3 is approximate to a reference detection value selected from an assumption part 4, a judging part 5 judges it as empty. Moreover, when a child seat which faces the back is mounted on a seat and data obtained by measuring by the distance measuring means 3 is approximate to the reference detection value selected from the assumption part 4, the judging part 5 judges that the child seat exists. As a result, it is possible to operate a control part 6 for starting an air bag 7 automatically after judging and detecting a seating condition as normal seating, empty, or a mounting condition of the child seat.

Title: Auxiliary device for teletext recording
Inventor: KURODA KAZUO
IPC: G11B20/00
Filed: 1993-06-28
Abstract: PURPOSE:To record a teletext data signal and a video signal on the same medium. CONSTITUTION:When the video signal including the teletext data signal is recorded on the recording medium, the teletext data signal is moved or copied to another horizontal line position and sent out. For example, inputted teletext data are temporarily stored in a field memory 15 and when row addresses correspond to 14th, 15th, 16th, and 21st horizontal periods of a TV signal, an address controller 14 changes them into row addresses of 21st, 22nd, 23nd, and 24th horizontal periods. When the row addresses correspond to 22nd, 23rd, and 24th horizontal periods, the field memory 15 is so controlled that the address controller 14 converts them into row addresses of 14th, 15th, and 16th horizontal periods. Consequently, the position of the character broadcast data is shifted to outside a switching section of the head of a VTR, so tha character broadcast data and image data can be recorded on the same medium at the same time.
