Title: Sliding door
Inventor: OKONOGI TAKAO
IPC: E05F15/10
Filed: 1993-09-06
Abstract: PURPOSE:To improve outward appearance, and prevent a danger of an occupant by arranging a holder on the tip of a pair of arms extending from the car body side so as to be slidable freely on a rail on an inside surface of a sliding door, and using a cover to hide the side surfaces of the arms to join a door side holder to a car body side base as a part of a door trim when the door is closed. CONSTITUTION:A sliding door where a rail is arranged on the door side, is composed of an upper trim 2, a lower trim 3, a sliding rail arranged between both trims 2 and 3, a holder fitted to the sliding rail having a U-shaped cross section, a pair of arms whose one end is pivoted on the holder and other end is pivoted on a base and an arm cover 8 to cover the arms, and the base is fixed to a car body. The pair of arms, the holder and the base create a parallel link mechanism. Since the arm cover 8 is situated on this side of the closest side of a seat 10 and covers the arms completely, a hand never touches the arms, and beautiful appearance can also be kept, and since a human hand or foot does not touch the arms when the door is closed, safety is heightened.

Title: Facsimile equipment
Inventor: TSUDA YUKIO
IPC: H04N1/21
Filed: 1988-09-28
Abstract: PURPOSE:To obtain a copy picture with high resolution through the use of a page memory with a storage capacity as less as possible by controlling a recording section and a reading section so that the reading speed is nearly equal constant with respect to the recording speed in the case of processing a high resolution reading picture signal at the copy operating mode. CONSTITUTION:A page memory 2 stores a reading picture signal sequentially in the copy operating mode and the operation is continued till a transfer instruction is given from a control section 6. When the transfer instruction is given from the control section 6 after the storage of a reading picture signal for several lines is finished, the page memory 2 transfers immediately a stored picture signal so far to a recording section (LBP) 4 through a changeover switch 8. The one-line read period in a reading section 5 is controlled to a constant speed equal to or nearly equal to one line recording period of the LBP 4. Thus, the storage capacity is enough to be the capacity able to store only one page of the reception picture signal at least corresponding to the resolution.

Title: Method for controlling polishing condition
Inventor: KATAOKA TAKAYUKI
IPC: B24B49/14
Filed: 1989-09-19
Abstract: PURPOSE:To detect a grinding burning in plunge cutting by wheel spindle motor power value by controlling grinding conditions such as grindstone feed speed and main spindle rotating speed in such a manner that a detected grinding resistance does not exceed a preliminarily set fixed grinding resistance. CONSTITUTION:A wheel spindle motor power value Wu corresponding to a lower limit hardness value Hd designated in designing is determined from a relational scheme H=f(W) and stored in a power comparative part 3. In this comparative part 3, a power value Wr obtained by a power meter 2 is compared with the wheel spindle motor power value Wu. When the result of the comparison shows Wr>=Wu, a signal  =Wr-Wu is transmitted to a grinding condition control part 4. In this control part 4, wheel spindle stock feed speed W is changed by a scheme V=V0- W.alpha and the wheel spindle stock feed speed of a grinding machine NC device 5 is reset to a value after the change. In this way, the motor power value is controlled in such a manner as to exceed a fixed value to control the ground material surface hardness, whereby a reduction in the surface hardness is prevented.

This coded signal is turned into a transmission signal that undergoes the reduction of the signal band width and the band compression and then sent to a transmission line 7. In such constitution, just a single transmitter suffices for plural cameras 1.

Title: Thermally stable planar heating element
Inventor: KAMEDA MAMORU
IPC: H05B3/14
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To suppress local heat radiation and provide heat radiation uniform in the whole surface area by using a fiber sheet consisting of evenly mixed short fibrous pulp of a non-conductive fiber which is not thermally melted and short fibrous chops of carbon fiber. SOLUTION: This planer heating element is produced by combining short fiber pulp of non-conductive fibers, which is not thermally melted, with carbon fiber chops and impregnating the resultant mixture with resin. The obtained mixture is formed into paper, sheets, mats, nonwoven cloth, fabrics, etc. Besides carbon fibers, metal fibers are supposed to be usable but in the case metals are used, the electric resistance is varied during the use due to rust and oxidation and thus metals are not preferable. In the sheet, short fiber chops of carbon fiber are uniformly dispersed and fixed without being partly concentrated. Consequently, the electric resistance value can be set freely by changing the contact of the short fiber chops of the carbon fiber. That is, the electric resistance is lowered and the highest achievable temperature can be heightened by increasing the content. Furthermore, based on the performance demanded, the non- conductive fiber pulp is mixed.

Title: Pen input display device
Inventor: TSUCHIDA KATSUYA
IPC: G06F3/0354
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To provide an input display device which has a highly accurate detection coordinate (high space resolution) and a light, thin, short and high time resolution by detecting a moved variable of a pen having an optical sensor when it moves on the display device based on space optical characteristics difference of the display device. SOLUTION: The moved variables of a pen input device 1 caused when it moves on a display device in an X direction (signal line direction) and a Y direction (Cs line direction) can be detected based on the space optical characteristic difference between the transmittance characteristic of a black matrix and that of each colored layer. Furthermore, an optical sensor of the device 1 easily receives the influence of the space optical characteristic difference of one of both directions of the display device since the receiving surface of the optical sensor has different lengths between the X and Y directions on the display device. Thus, it is possible to detect with higher accuracy whether the device 1 moved in the X or Y direction.

Title: Temperature compensating circuit for dc stabilized power supply
Inventor: HAMADATE SHUNICHI
IPC: G05F1/56
Filed: 1985-11-01
Abstract: PURPOSE:To obtain a safe DC voltage by controlling the both-terminal voltage of the 2nd voltage limit element and compensating the voltage drift of a Zener diode due to a temperature change. CONSTITUTION:The base-emitter voltage Vbe of a transistor TR21 drops when the ambient temperature T rises up as shown by a straight line A. Thus the potential at a point between a Zener diode 18 and a resistance 19 has the temperature characteristic approximately proportional to the line A as shown by a straight line B. Here the values of resistances 19 and 20 are set so that the gradient of the line B has the relation opposite to the temperature characteristics of the diode 18. Thus the the voltage generated at a power supply terminal 17 can be compensated so that it is approximately constant regardless of the temperature change as shown by a straight line C. Therefore the base-emitter voltage Vbe of the TR21 having the temperature characteristics opposite to the diode 18 is used to compensate the drift due to the temperature change of the Zener voltage. Thus it is possible to obtain the stable output voltage in a simple constitution.
