IPC: G01R29/08
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To correctly compensate non-linear items of a wave detection diode irrespective of a change in environmental conditions when a wave detector is used in measuring high frequency small signal power such as a microwave radiator. SOLUTION: A voltage variable attenuator 11 for adjusting output power of high frequency oscillators 8, 9 different in frequency so that it is equal to input power of a wave detection diode 2 is connected to a distortion detection diode 12 having equal wave detection characteristics to those of the wave detection diode 2. Then, among output signal components of the distortion detection diodes 12, harmonic signals generated by non-linearity of the wave detection characteristics are separated with harmonic components by a primary harmonic filter 13 and a secondary harmonic filter 13 and converted into DC voltage by DC conversion diodes 15a, 15b, and thereafter items to be compensated of non-linearity are calculated by a signal divider 16 and a signal multiplier 17, for compensating non-linear items of the wave detection diode 2 by a signal adder 5.

Title: Method and device for improving micro-mechanical modulator
Inventor: SUZANNU SHII AANII
IPC: H03C7/02
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To minimize concentration of stress and to improve characteristics of a modulator by forming a circular thin film over the certain region of the substrate so that a spacing is provided between the film and the substrate. SOLUTION: A thin film 15 and a substrate 10 are separated from each other and a spacing 20 is specified. Preferably plural holes 14 are formed in the film 15 and arranged in the radial direction. The holes act to reduce the vibration of the film 15 and they are used during the production of the modulator. The holes 14 are pattern formed on the film 15, starting from the outside a region 16 which is arranged at the center and the holes 14 are spread to the direction toward an edge 19 of the film 15. The region 16 forms an optical window. The film 15 is overlapped with most of the edge of a modulator cavity 21. It is preferred to make the film 15 in a circular shape. Also, bias signals are applied to the substrate 10 and the film 15, which are electrically conductive, so as to generate an electro-static force. Thus, the film 15 moves toward the substrate 10 due to the force. Note that as the film 15 moves to a position from the position where no bias is applied and the reflectivity of the modulator is varied against incident optical signals.

Title: 1/7 code modulation system
Inventor: ITOI TETSUSHI
IPC: H03M7/14
Filed: 1989-01-27
Abstract: PURPOSE:To obviate a special table selection circuit by using a 2/4 conversion table converting a 2-bit data bit into a 4-bit channel bit and a 3/4 conversion table converting a 3-bit data bit into a 6-bit channel bit depending on the situation and applying code conversion. CONSTITUTION:A discrimination circuit 14 discriminates whether or not a head bit of a data bit converted into a parallel is '0' or '1' and the result is fed to a conversion ROM 16 via a next stage serial/parallel conversion circuit 15. Two kinds of conversion tables as 2/4 conversion table and 3/6 conversion table are stored in the conversion ROM 16 and the conversion table to be in use is selected in response to the head bit '0' or '1'. Thus, a channel bit whose minimum code inversion interval Tmin is 1.5 time a bit interval T and whose maximum code inversion interval Tmax is 4 times the bit interval T is obtained without using any special table section circuit at all.

Title: Image forming device
Inventor: FUNABASHI EIJI
IPC: G03G15/02
Filed: 1992-01-07
Abstract: PURPOSE:To properly electrify the surface of a photosensitive drum by using a sheet-like member for a contact electrifier and simultaneously, making a contact part with the photosensitive drum into an insulator. CONSTITUTION:An electrostatic charge bias from a power source 9 is applied on the electrode layer 22 of the contact electrifier 2. The insulator 23 insert-held between two electrode layers 22, has a fairly high resistance value, and is not charged, so that a charge is hardly injected to the surface of the photosensitive drum 1 from the insulator 23, but solely infected to a resistance layer 25. Therefore, the high voltage of the power source 9 is applied between the resistance layer 25 and the surface of the photosensitive drum 1, and discharging is carried out in fine gaps Z1 and Z2, and the surface of the photosensitive drum 1 is uniformly electrified.

IPC: C23D5/06
Filed: 1979-02-21
Abstract: PURPOSE: To apply many and diversified kinds of decorations free from flaws on both sides of table utensiles, etc. by firing and setting the cloisonne glaze mixed with glue on the top surface of the ware body then facing this cloisonne layer downward, supporting the same with needles and applying cloisonne firing to the bottom surface of the ware body.  
     CONSTITUTION: The cloisonne glaze mixed with glue 2 such as wheat starch glue, CMC is fired and fixed on the top surface of a ware body 1 such as spoon. With this cloizonne layer 3 being faced downward, the ware body 1 is horizontally supported by a number of needles 4 and the cloisonne glaze is fired on the bottom surface of the ware body 1 faced upward, whereby the cloisonne layer 5 is formed. At this time, the closionne layer 3 is closely contacted to the ware body 1 by the glue 2, hence it will not drop even if it is again fired and melted by high temperature. The small holes formed by the needles 4 in the cloisonne layer 3 become small when cooled after the firing, thus the impairment of the beauty is obviated.
