Patent JP-H0435516-A (JP)
Title: Surface acoustic wave multiple mode filter and its passing band characteristic adjusting method
Inventor: MIYAJIMA HAJIME
IPC: H03H9/64
Filed: 1990-05-31
Abstract: PURPOSE:To facilitate the adjustment of passing band width by grounding a conductor pattern for connecting inter-digital electrodes through a variable capacity element such as a variable capacity diode, etc., and adjusting the capacity in accordance with an output of the post-stage. CONSTITUTION:On the same piezoelectric substrates 10, plural surface acoustic wave resonators consisting of inter-digital electrodes 11 - 14 and reflectors 15 - 18 for inserting and holding them are placed adjacently, coupled acoustically, and used between a tuner of a receiver and an intermediate frequency amplification stage. Also, a variable capacity element 21 is connected to a conductor pattern 20 for connecting the inter-digital electrodes 11 - 14 and an earth, and a voltage applied to the variable capacity element 21 is controlled by an output of the intermediate frequency amplification stage. Accordingly, when the capacity connected to the conductor pattern for connecting the inter-digital electrodes 11 - 14 to an earth potential is varied, passing band width and a group delay time are varied. In such a way, since the passing band width can be varied by adjusting the capacity, a passing band characteristic can be aligned easily with a desired characteristic.

Title: Laser welding method and optical semiconductor module
Inventor: AOKI HIROATSU
IPC: B23K26/21
Filed: 1992-06-03
Abstract: PURPOSE:To avoid deterioration in optimum optical coupling such as the deviation of an optical axis in laser welding between members composing an optical semiconductor module. CONSTITUTION:At the time of fitting a member with a small outer dimension into a member with a large outer dimension and welding them together by a laser beam, by tapering the surface in the proximity of the welding part of the member with a large outer dimension, the tensile force that is actuated on both the members at the time of welding is reduced. In the optical semiconductor module, by tapering the tip end part of the side panels in 15A and 15B of a lens holder guide 15, a force D to draw in a lens holder 14 into the lens holder guide 15 is reduced. In like manner, by tapering the end part of an optical fiber guide, the force by which the optical fiber holder is drawn in the optical fiber guide is reduced, as the optical fiber guide is pulled and a space is caused between the guide and the lens holder in the case where the optical fiber holder is fixed by a chuck. Thus, the optimum optical coupling is maintained by avoiding deteriorations including the deviation in the optical axis among a light emitting element, lens and optical fiber.

Abstract: PURPOSE:To fabricate a template for oral cavity, which suits the forms of teeth and their arrangement, through simple procedure in a short time by forming a template fabricating device from a body having a pair of guides, which are arranged on both sides of the upper and lower rows of teeth at the time of meshing with each other, and a spacer provided in the neighborhood of the foreteeth. CONSTITUTION:The body 2 of a template fabricating device for oral cavity is molded in a soft material of rubber type and equipped with a pair of guides 4, 4 constructed in U-forms approx. the same as the shapes of the human teeth rows 3, 3. The space between these guide parts 4, 4 except a spacer part 5 in the body 2 is filled with a molding material for template, and the body 2 is pressed by finger so as to fit the teeth row 3 and located in the oral cavity, followed by meshing with each other. The meshing pressure is applied to the molding material, and the tooth forms are impressed. Because contacting the spacer 5, the upper and lower foreteeth are hindered from meshing. After hardening of the molding material, the meshing is released, and the body 2 is taken out of the oral cavity by grasping a grip 7 with fingers. The molding material is removed from the body 2, and the surplus portion is cut away by a knife, and thus a template 8 which best suits the forms of back teeth is accomplished.

IPC: F23N3/08
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To inexpensively detect a fan motor current in a combustion equipment without being affected by a temperature. SOLUTION: A resistance R of a current.voltage converting means is connected to an output side of a fan motor driving circuit. A voltage.duty ratio converting circuit 30 is connected in both ends of the resistance R to convert a voltage between the both ends into a pulse signal of a duty ratio corresponding to the height of the voltage. The pulse signal of the duty ratio in response to a voltage value converted by the voltage.duty ratio converting circuit 30 transmits accurately a fan motor current because the duty ratio is not affected even when its frequency varys with change of an ambient temperature. The pulse signal is transmitted using a photocoupler 35 while keeping an insulated condition between a driving side of a fan motor and a control circuit side, so as to be converted into a voltage signal in response to the duty ratio by a smothing circuit 43.  A fan motor current value free from influence of a temperature is provided by a control circuit 40 based on the voltage signal.

Abstract: PURPOSE:To simplify constitution as much as possible, by placing an electronic switch for a connection line between a recording and playback head and a recording amplifier in a prescribed state, and stopping the recording amplifier in reproduction and driving it in recording. CONSTITUTION:In recording, for example, a transistor (TR)Q1 turns off, and a TRQ2 on; and a TRQ3 turns off, and a TRQ4 off.

Title: Soi substrate
Inventor: KATO YUICHI
IPC: H01L29/78
Filed: 1990-05-30
Abstract: PURPOSE:To increase the impurity concentration near the insulating film interface of an element formation layer for avoiding the inversion thereby reducing the back channel work current in off time by a method wherein an insulator containing high concentration impurities is adapted in an SOI substrate to increase the impurity concentration near the interface between the insulator and a semiconductor layer by solid diffusion. CONSTITUTION:A P-type semiconductor substrate 3 is formed on a semiconductor tentative substrate 1 and a silicon dioxide film 2 (to be called BSG later on) containing high concentration boron. The formation process may be either epitaxial or bonding process. The boron as impurities is diffused from BSG 2 to the substrate 3 in the heat treatment during the element formation process to form a high concentration impurity layer 4. Due to the existence of the layer 4, a back channel is hardly formed on the rear side of the substrate 3 also the leakage current of an element hardly runs away. On the other hand, the heat treatment may suffice for the element formation process or may be especially required of the specific heat treatment. At this time, the judgment depends upon the concentration profile computed by the segregation and the diffusion length of the impurities.
