Title: Car seat
Inventor: KATSURAGI MICHIHIRO
IPC: A47C7/50
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To obtain a seat back angle corresponding to the physique or liking of an occupant by making it possible to independently adjust the position of an ottoman interlocked with a seat back from the interlocking position. SOLUTION: When a back frame 105 is tilted by turning a reclining 107, point A is transferred forward by a link 111 and point B of a nut 114 supporting the lower side of an ottoman 102 through a link 112 is also transferred backward to shake out the ottoman to a position where it can be used. When a ball screw 113 is rotated around a shaft through a bevel gear by turning a dial 103 and the nut 114 is rotated to the rising side, the ottoman 102 is transferred to the horizontal position. When the nut 114 is rotated to the lowering side, the ottoman 102 is transferred to the vertical position and the angle of the ottoman 102 can be adjusted independently from the position interlocked with the seat back. Hence, an occupant can adjust the relation of the seat back angle and the ottoman angle in accordance with his physique or liking.

Title: Tension measuring method and equipment in block
Inventor: MIYAGAWA KAZUO
IPC: G01L5/04
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To enable accurately measuring the tension on the infeed side and the outfeed side when a cable is stretched by using a block, by measuring physical amounts and using a specified formula. SOLUTION: A cable 19 is streched by using a block 17 suspended with degree of freedom. The tension of the block 17 in the center line O-P direction is measured with a tension meter 12. Angles 41, 42 on the feeding side and the sending-out side formed by the cable 19 and the line O-P are measured with Angle sensors 21, 22. A pitch angle θp between the vertical line O-N of the block 17 and the block 17 surface, and a roll angle θr between the line O-P and a projection line O-N' of the line O-N on the block 17 surface are measured with angle measuring apparatuses 16, 15. These data, the self weight W of the block 17, the distance L from a retaining point O to the block 17, and the radius (r) of the block 17 are substituted into a formula.  Thereby the tension F1 of the feeding side of the cable 19 and the tension F2 of the sending- out side which are applied to the block 17 are obtained. Hence the right and the left tensions during streching can be accurately measured.

Title: Image forming device
Inventor: MATSUURA MASAMI
IPC: G03G15/00
Filed: 1995-03-17
Abstract: PURPOSE: To prevent the decrease of an electrifying voltage and to obtain a high quality image by sticking toner to a photoreceptor region receiving only a reverse charge with a developing means, at the time of forming an image in a reflection developing mode. CONSTITUTION: When an electrifying charger 32 and a transfer charger 37 are simultaneously turned on, the discharge of the electrifying charger 32 is not received but the discharge of the transfer charger 37 is received by the arrangement relation of the chargers 32 and 37. Thus, when an image forming region receiving only the reverse charge passes through a developing unit 36, a developing sleeve 36a is driven to rotate and a developing bias voltage having a value equal to that in reversal development to the sleeve 36a. Since the surface potential of the region receiving only the reverse charge is of a residual potential, the toner is solidly stuck to the region. When the discharge from the transfer charger 37 is received in this state, the toner is negatively electrified, but a photoreceptor 31 is not directly charged.  Therefore, the residual potential becomes the same level as that of the positively charged region.

Title: Sealing device for desorption zone in gas treatment device
Inventor: ITOU YOSHIBUMI
IPC: B01D53/81
Filed: 1980-05-06
Abstract: PURPOSE: To prevent reduction in desulfurizing efficiency and the occurrence of a fire from being caused by the leakage of a desorbed gas, by a method wherein when conducting desorption in a desorption zone in a rotary cylindrical body, a sealing member is fitted to the compartment being located in the desorption zone so as to shield the compartment from others.

When the compartment is moved into the desorption zone and sulfur oxides are desorbed by heating an adsorbent in the compartment, pressurized water is fed into the bellows 23 through a conduit 30 to extend the bellows 23. A packing 24 supported by a packing-supporting member 25 at the tip end of the bellows 23 is closely contacted to a pressure-receiving part 29 of a column 8 of the compartment 24 so as to secure airtightness, thereby preventing the hot gas in the desorption zone from leaking out into other zones. When the desorption is completed, the pressurized water is discharged from the interior of the bellows 23 and the compartment is moved.

Abstract: PURPOSE:To prevent the failure of synchronization by revolving a polygon scanner motor till the temp. of a fixing roller reaches a controlled one (warming up), and self-generating heat, when the temp. of a temperature sensor reaches a prescribed one or below. CONSTITUTION:Even if the various conditions of the fixing roller, etc., except the PLL circuit 108 of the polygon scanner motor 109 supplying a power source into a device and carrying out printing out are compiled for an operation at the time of a low temp., the temp. of the PLL circuit 108 is not in the normal operating ranges of a circuit element, etc., so that the failure in the synchronization is caused at the time of an image formation. When the temp. of the fixing roller detected by a fixing thermistor 101 at the time of supplying the power source is lower than the prescribed one TSLC, it is judged that the temp. surrounding the PLL circuit 108 is low, as well, the polygon scanner motor 109 is turned on to self-generate the heat. Thus, the temp. surrounding the PLL circuit 108 is raisen, and the occurrence of the failure in the synchronization is prevented.

Inventor: WATANABE AKITO
IPC: G06G7/18
Filed: 1989-03-10
Abstract: PURPOSE:To prevent an integral error from being accumulated by quantization by adding the quantization error, which is generated at the time of A-D conversion, obtained by an analog subtracter to the input voltage of the next A-D conversion by an analog adder. CONSTITUTION:When a start signal S is received, at first, a control logic circuit 3 resets an output H of a sample hold circuit 1 and an analog output Q from an A-D converter 2 according to reset signals R1 and R2. The output H of the sample hold circuit 1 and the analog output Q from the A-D converter 2 when the A-D conversion is finished are inputted to an analog subtracter 5 and a quantization error E=H-Q is outputted. This quantization error E is added to an input voltage V by an analog adder 6. Afterwards, sample hold and A-D conversion is samely repeated and as a result, the quantization error generated at certain timing by the A-D conversion is added to the input voltage of the next A-D conversion. Thus, the error can be prevented from being accumulated.
