Abstract: PURPOSE:To remove the influence of differential revolution attributable to the reduction in the pneumatic pressure of a tire or the fitting of a different-diameter tire, in the differential limiting control. CONSTITUTION:The connection torque of an electromagnetic multiple disk clutch as the center differential gear of a four-wheel drive vehicle is set by the total torque of differential revolution reflected connection torque, estimated transverse acceleration reflected connection torque, and vehicle speed reflected connection torque.

Title: Video signal recording medium playing device
Inventor: KURODA KAZUO
IPC: H04N5/85
Filed: 1990-07-16
Abstract: PURPOSE:To prevent disturbance of a reproduced picture at mode changeover by gradually decreasing a generating period of a reference vertical synchronizing signal in a video signal recording medium device and increasing again after the decrease and switching the reproduction mode when a phase difference arrives in a prescribed range. CONSTITUTION:A mode command instruction from an operating section 23 is fed to a put-in control circuit 30. Other operating instructions than the mode designation instruction are fed to a system controller 8 from the operating section 23. Moreover, a PBV from a time axis control circuit 6 is fed to the put-in control circuit 30. A reset signal to a signal generator 9 is given from the put-in control circuit 30 and a REFV and REFH using the reset signal as a trigger signal are fed to a memory controller 7 and the put-in control circuit 30. A phase difference between a reproduced vertical synchronizing signal and a reference vertical synchronizing signal is detected at the changeover of the normal reproduction mode and the special reproduction mode and when the phase difference stays at the outside of the prescribed range, the generating period of the reference vertical synchronizing signal is gradually decreased or increased and again increased or decreased after the decrease or increase and the changeover or the reproduction mode is implemented when the phase difference reaches the prescribed range. Thus, disturbance in the reproduced picture at the changeover of the reproduction mode is eliminated.

Title: Manufacture of semiconductor substrate
Inventor: SAITO YUICHI
IPC: H01L21/322
Filed: 1987-07-28
Abstract: PURPOSE:To prevent the warpage of a semiconductor substrate by irradiating the rear of the semiconductor substrate with beams to generate the nuclei of gettering and removing at least one surface layer of the surface or the rear of the semiconductor substrate. CONSTITUTION:The rear 1a of a semiconductor substrate 1 is irradiated with laser beams, but the point is the generation of the nuclei of gettering such as the generation of dislocation or strain. When laser beams are applied, the temperature of the rear 1a of a laserbeam irradiation surface is elevated to a temperature lower than the boiling point but higher than the melting point, and the properties of the surface layer of the rear 1a are changed. The surface layer of the rear 1a of the semiconductor substrate 1 under the state in which warpage and irregularities are formed is removed through the next process. One part or the whole of a recrystallizing layer (an amorphous layer) 1a1 may be gotten rid of at that time, or it may be taken off more deeply, but depth in which at least said dislocation 1a2 is left after the removal of the surface layer must be shaped. A mechanochemical method in which SiO2 powder is mixed into an alkaline solution and the surface layer is polished is used as a removal means.

Title: Image forming device
Inventor: ARAYA JUNJI
IPC: G03G15/16
Filed: 1988-07-29
Abstract: PURPOSE:To prevent transfer memory, defective transfer, and contamination of a transfer member caused by reversal fog by switching a bias voltage impressed in order to transfer a toner image at either forward or backward end of a transfer material. CONSTITUTION:When a toner image reaches a transfer part where the photosensitive body 1 abuts on a transfer roller 2, a transfer material is supplied to the transfer part from a carrying path 4. At the same time, a transfer bias (a first transfer bias) is impressed to the transfer roller 2 by a power supply 2b; and the toner image on the photosensitive body side is transferred onto the transfer material, and then it is carried to a fixing part A. Transfer bias (a second transfer bias) is impressed to both front and trailing area of the transfer material, and the second bias of a paper nonpassing part is switched to the first bias in a paper passing part and the switched one is impressed. The second transfer bias has such a degree that transfer memory does not arise in the paper nonpassing area. Thus, contamination of the transfer member caused by reversal fogging is effectively prevented without generating transfer memory and defective transfer.

Abstract: PURPOSE:To obtain a line image having substantial density even if a one-component toner is used by providing a composite layer of rubber and magnetic material on a conductive base and magnetizing the composite layer then forming an electrode layer embedded with many conductive particles into a dielectric adhesive agent on the surface of the rubber layer. CONSTITUTION:A composite layer 5' consisting of rubber and magnetic material powder is formed on, for example, a circular cylindrical conductive base 4 and thereafter the composite layer is magnetized to form a rubber magnet layer having a thickness t5'. The surface is then ground to form a smoothed layer 5. A dielectric adhesive agent layer 6b is thinly formed on the layer 5 and after conductive particles 6a are adhered to the layer 5, the adhesive agent 6b is dried. The particles 6a are coated with the same or different adhesive agent 6b' and thereafter the adhesive agents 6b, 6b' are cured. The surface is ground to expose the surface area of the particles 6a to >=45% of the entire surface area of the electrode layer 6 and is finished smooth to such a thickness t6 at which dislodging of the particles 6a is prevented. The developer carrying body to provide the one-component toner image with which the substantial density of even the line image is obtainable is thus obtd.

Title: Front-back adjustable stepping pedal
Inventor: ASANO YASUSHI
IPC: B60K26/02
Filed: 1988-07-28
Abstract: PURPOSE:To realize the front-back adjustment of a pedal by moving front and back a pedal pad to set it at a proper position, moving a pedal arm in parallel to keep the pad at the fixed height, and keeping the lever ratio of the pedal arm at a fixed level via a control lever. CONSTITUTION:The position of a pedal pad 22 is adjusted when a pedal arm 18 is moved toward an operator (right). When a screw nut 19 moves via a motor, a pin 17 moves along an arc-shaped hole 6b of a control lever 6. Thus a pin 8 is pushed along an arc-shaped hole 7 of a lever 3. At the same time, a link 9 turns clockwise around an axis 12 of a sublever 11. In such a case, the distance DS between an axis 2 and the pin 8 varies in proportion to the distance DL between the axis 2 and the pad 22. A tension spring 15 functions to keep the lever 3 at a fixed position. Then the pad 22 is treadled after adjustment of its position. Thus the lever 3 turns around the axis 2 together with the arm 18, and a control lever 13 is moved to the left.
