Title: Pneumatic tire
Inventor: HASHIMURA YOSHIAKI
IPC: B60C9/08
Filed: 1993-09-13
Abstract: PURPOSE:To enhance the wet performance by increasing a ratio between a maximum ground- contact length of a pneumatic tire having a shape, in which a circumferential length of the tire is maximum when it passes the centre of the ground-contact wound and it gradually becomes shorter toward both sides of the tire, and a ground-contact length at a position close to the outside of the tire and lessening a total ground contact part groove-area-ratio together with further lessening the groove-area-ratio at the central ground contact part. CONSTITUTION:With regard to the ground contact shape of the tread surface of a tire, a ground contact length in the circumferential direction of the tire at the center O of the maximum ground contact width W is maximum M, while the ground contact length in the circumferential direction of the tire on both right and left part gradually becomes shorter. In this case, a ratio between the maximum ground contract length M and a ground contact length m in the circumferential direction of the tire at a position D, which is apart from the ground contact center CL toward both sides by 90% of the maximum ground constact width W/2, respectively, or m/M, is set at 0.65 to 0.80. In addition, the total ground contact groove-area- ratio of the tread surface is set at 20 to 50%, while a central groove-area-ratio in a central part region E corresponding to 40% of the maximum ground contact width W is made smaller than the total ground contact part groove-area-ratio. Thus, since water hardly enters the central part of the tread surface, wet performance of the tire can be enhanced.

Abstract: PURPOSE:To enable development which uses a liquid developing material by providing a recording part, a development part, a transfer part, a cleaner part, and a demagnetizing part in order in the rotating direction of a magnetic drum and arranging a porous base between a magnetic drum and a developing unit. CONSTITUTION:Only the liquid developing material 14 which is swelled with electrostatic charges contacts the magnetic drum 1 to perform development.

Consequently, even if the liquid developing material 14 sticks on a no-image part, the material is never left at the no-image part because of the electrostatic attractive force. Therefore, the liquid development material sticks on only a magnetic latent image part where a magnetic attractive force is prevent to form a sharp visible image 13. Consequently, the development which uses the liquid developing material is enabled.

Title: Drive controller for brushless motor
Inventor: KIYOMA TOSHIAKI
IPC: H02P6/08
Filed: 1989-09-01
Abstract: PURPOSE:To eliminate effects of spike noise in the waveform of current flowing through driving coils and effects of the variation in supply voltage and load by providing a phase control loop in which power switching signals maintain definite relations in phase with respect to both the rotor position and speed. CONSTITUTION:A driving coil 1 is energized in accordance with power command signals UH and UL which are synchronized with an output (f) from a voltage controlled oscillator 40. During the absence of the signals UH and UL, the coil 1 is de-energized, and the waveform UO of current in the driving coil coincides with that of the counterelectromotive force. The de-energization lasts until the signal UL rises after the signal UH falls to LOW. This period is corresponding to two clocks of (f). The voltage waveform at the neutral point of each coil is compared with that of energizing current by a phase error comparator to detect the phase difference. Another period of de-energization lasts from a fall of UL to LOW to a rise of UH, and another phase error comparator 21 operates in the same manner as above.

IPC: H01G4/12
Filed: 1989-09-01
Abstract: PURPOSE:To largely improve heat resistance in the case of soldering by providing supporting layers in an uppermost layer and a lowermost layer, alternately laminating inner electrodes and ceramic dielectric layers to be integrated at the center, forming outer electrodes at both ends where the inner electrode is exposed, and covering an element surface except the outer electrodes with wax. CONSTITUTION:Green sheets of a ceramic dielectric layer are sequentially laminated on a pallet by using a press, and a supporting layer 14 of a lowermost layer which does not contribute to the capacitance of an electric device is formed. Thereafter, a step of forming an inner electrode 12 on the sheet and a step of laminating the sheet 11 are repeated by once deviating the inner electrode to obtain a in-process capacitance, and when a lamination is completed, the layer 14 which does not contribute to the capacitance is formed on the uppermost layer. Then, a laminated layer molded form is cut into chips, baked, and outer electrodes 13 are then formed at the end of the side in which the inner electrode is exposed. The obtained laminated ceramic capacitor is dipped in a wax tank to form a coating layer 15, and the film of the wax adhered to the outer electrodes is removed.

IPC: G06F13/00
Filed: 1988-09-12
Abstract: PURPOSE:To quickly cope with the error information by transmitting a signal when the number of pieces of error information reaches a prescribed level and informing a fact that the prescribed number of error information are logged into a memory. CONSTITUTION:A control means 4 transmits a signal when a fact is detected that the number of pieces of error information reach a prescribed level. Based on this signal, an informing means 5 informs the collection of the error information. Thus it is informed that the prescribed number of error information are logged into a memory 6. Thus a communication controller 2 can dump the collected error information when they are logged in the prescribed number and can quickly cope with the error information. Furthermore it is possible to avoid such failures or useless jobs where the error information is not dumped before a serious fault occurs or a dumping action is performed even with the absence of the error information.
