Title: Rotating polygon mirror
Inventor: SAKAMOTO MASANOBU
IPC: G02B26/12
Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To reduce the deformation of a mirror surface part and to realize high speed rotation by providing inclination so that thickness may be gradually decreased to a reflection surface from the vicinity of a bearing surface on which a regular polygon mirror is fixed and making the thickness of the reflection surface equal to or above a specified value. SOLUTION: An air-core type stator coil 8 is fixed in an end case 12 and oppsitely arranged to be concentrical and in non-contact with a magnet for a motor 6 inside a rotating cylindrical body 1, thereby constituting a motor part for rotating and driving. A permanent magnet 5 is arranged near the center inside the end case 12 and combined with another permanent magnet 4 to form a thrust bearing. In such a case, the inclination is formed to the mirror surface part 3 from the vicinity of the bearing surface 16 where the cylindrical body 1 and the regular polygon mirror 2 are fixed, so that the mirror surface part 3 becomes thin, loss caused by air friction is reduced and input is reduced. Then, the minimum thickness of the mirror surface part 3 is set to about 0.5mm considering dispersion in dimension and assembly.

IPC: H04B7/10
Filed: 1990-08-03
Abstract: PURPOSE:To prevent the deterioration of communication quality by suppressing one arbitrary polarized wave to take out the signal of the other desired polar ized wave when the two polarized waves with different frequencies each other are jointly transmitted and receiving one desired polarized wave. CONSTITUTION:The signal including two polarized waves is branched by a signal branching circuit 20, one of the branched signals is turned to be the wavelength whose difference of electric length against respective polarized waves is approximately 1/2 multiple of odd number by a polarized wave selec tion circuit 30, further, amplitude phase is controlled. Moreover, the polarized wave selection circuit 30 synthesizes and branches the other branched signal, detects the amount of control of the amplitude phase to input the other to a receiver 40, and receives one desired polarized wave. Thus, the communication quality can be maintained without affected by the cross polarized wave interfer ence even at the time of the deterioration of cross polarized wave discrimination degree caused by a rainfall.

Title: Communicating method, transmission power control method and mobile station thereof
Inventor: YAMAURA TOMOYA
IPC: H04B7/26
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To satisfactorily control communication power, when performing communication in a TDMA system by controlling transmission power in each time slot period based on actual receiving signal quality. SOLUTION: A controller 180 of a mobile of a mobile station stores receiving power measured results in a slot unit over several past receiving slots and predicts the receiving power of the next receiving slot by means of an algorithm consisting of them. The controller 180 supplies a control signal, showing power value to be transmitted and a control signal showing the reference of transmission power to a computer 182. The computer 182 compares them and adjusts the gain of a transmission system gain control circuit 166. When the estimated value of receiving power is larger than the reference of predefined transmission power, the power value to be transmitted is made small value by the difference. When the estimated value of the receiving power is smaller than the reference, it is made large in value by that difference amount.

Title: Active matrix type liquid crystal display device and its production
Inventor: TAKAHATA MASARU
IPC: G02F1/136
Filed: 1994-08-31
Abstract: PURPOSE: To decrease the reduction in the numerical aperture and the production yield by forming the planer structures in odd lines and even lines of pixels in a mirror inversion structure. CONSTITUTION: A thin film transistor(TFT) having a gate insulating film/ semiconductor film is formed as a switching element just under or on the a electrode 3. The planar structure in an even line of pixels and the planar structure in an odd line are formed in a mirror inversion structure to each other. Since the structure of pixels in the odd lines and the structure of pixels in the even lines are symmetric for a line, the channel length L of the parasitic TFT (the distance between the source electrode 2-1 in one pixel and the drain electrode 1-2 in the adjacent pixel) becomes longer than a conventional structure. As a result, influences of the display signal voltage applied from the drain electrode 1-2 in the adjacent pixel is reduced.  Thereby, a conventional drain electrode formed to prevent mixing of display signal voltage from a drain electrode 1-2 in the adjacent pixel is not necessary. Thus, the reduction of numerical aperture and production yield can be prevented.

Filed: 1990-08-04
Abstract: PURPOSE:To restrict generation of output reducing or the like of an internal combustion engine to the minimum by moving the opening position of a valve to the full opening or full closing position, when an abnormal condition is detected on a detecting part for detecting the opening position of the valve, or on a driving part for driving the valve. CONSTITUTION:In an intake air passage of an engine 1, a valve 5 which is driven to be open/close is provided so as to control the length of the passage long or short. In this case, the target opening value of a valve 5 corresponding to the operating condition of the engine 1, which is detected by an intake air quantity sensor 2 and a crank angle sensor 4, is memorized beforehand in a controller 8. On the other hand, a real valve opening value is found out on the basis of a valve opening detection signal from a valve opening detection circuit 7 composed of a Hall sensor or the like, and thereby comparison with the valve opening and the target opening is carried out. As a result, a driving circuit 6 composed of a DC motor or the like is driven when the actual valve opening is different from the target opening. When it is judged that the valve driving circuit 6 or the valve opening detecting circuit 7 is in an abnormal condition, the opening position of a valve 5 is controlled to the full closing or full opening position.
