Title: Transceiver using microwave integrated circuit
Inventor: ISHIZAKI MASAYUKI
IPC: H01P1/00
Filed: 1983-05-27
Abstract: PURPOSE:To attain miniaturization by containing a transmitter, a receiver and an antenna on one dielectric board so as to simplify the constitution. CONSTITUTION:When a DC bias voltage is applied to a solid-state oscillating element 401, the element is oscillated in a resonance frequency of a resonator 402 formed by a microstrip line and the oscillated output is irradiated externally through a zigzag antenna 44 having the directivity, a terminal 1 and a line 43. On the other hand, the radio wave received by the antenna 44 is applied to a mixer section 42 through terminals 1, 2 of the coupler 41. Then, the received wave of the antenna 44 is mixed with an output of an oscillator 40 at a diode 421 and a wave having a frequency being a difference of two waves is obtained.

Title: Resonator
Inventor: SAGAWA MORIKAZU
IPC: H01P7/08
Filed: 1989-04-13
Abstract: PURPOSE:To miniaturize a resonator by connecting the open ends of lines, which are doubly connected to a center line and its both ends by means of capacity elements. CONSTITUTION:The lines 11-14 having an impedance twice as much as that of the center line 10 are doubly connected to both ends of the center line 10, and the impedance of the center line 10 is set to be the same as the synthesized impedance of the lines 11-14 connected to the center line. The capacity element 15 is connected to the open ends of the lines 11 and 12, and the capacity element 16 to the open ends of the lines 13 and 14. Thus, the form of the resonator can be miniaturized by the operation of the capacity elements 15 and 16. Furthermore, a resonance frequency can be adjusted by controlling the values of the capacity elements to be added.

IPC: B65D33/14
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To provide a simple package which does not require much labor in the production and reduces the production cost and further, has a sufficient strength. SOLUTION: This simple package 1 packaging an article to be packaged 5 so as to be able to visually confirm it from the outside, is formed by a transparent polypropylene material and constituted of a packaging bag 4 containing the article 5 and a base board 2 on which polypropylene material is applied on the surface. One end of the packaging bag 4 and the surface of the base board 2 are heated and welded together. In this way, since the packaging bag 4 is stuck to the base board 2, the simple package 1 having a sufficient strength can be produced very easily and the production cost can be remarkably reduced as a merit. And even if the packaging bag 4 is made of a transparent polyethylene material, a sufficient welded strength together with polypropylene material of the base board 2 can be obtained.

Title: Edge part settlement structure of valley gutter
Inventor: SATO HIDEO
IPC: E04D13/064
Filed: 1991-04-24
Abstract: PURPOSE:To prevent damage such as crack and deformation by providing a water stop plate, which is arranged inclined so that its upper edge approaches to the inside face of a decorative member and its lower edge separates from the inside face of the decorative member, on an edge part facing to the decorative member. CONSTITUTION:A valley gutter 3 is arranged close to the inside face of a decorative member 1 so that it stands against the decorative member 1 like a parapet by installing it between both of roof plates 4 and constituting water stops 2 on both edges of a valley gutter main body 3a of a U-letter shape in section opening the upper face of the valley gutter 3. Next, in the case when the valley gutter 3 extends due to change of temperature, the edge part of the valley gutter 3 makes contact with the inside face of the decorative member 1 and the edge part of the valley gutter 3 is guided upward by the water stop plate 2. Conversely, in the case when water staying at the edge part of the valley gutter 3 freezes in winter, stress generated at the time of freezing is released diagonally upward above the water stop plate 2 and it does not work to press to the outside. Consequently, it is possible to prevent damage of the valley gutter 3.

Patent JP-S63262040-A (JP)
Title: Preparation of vibration-proof magnetic alloy
Inventor: IIKAWA TSUTOMU
IPC: H02K5/24
Filed: 1987-04-16
Abstract: PURPOSE:To prevent the change of dimension, by using Fe-Si alloy powder containing numerous Si atoms more than the alloy composition at target, by adding Fe powder and by mixing C to sinter the powder. CONSTITUTION:The fusing point of Fe is as high as 1335 deg.C, but it will be lowered if its alloy is made with C or Si. The entectic temperature of Fe-Si-C line is 1150 deg.C, but that of Fe-Si will be lowered more than that. On that account, the sintering performed at 1140 deg.C with C added to the alloy powder expressed as the composition formula Fe-xSi will produce liquid phase on the contact interface of Fe-xSi particles with C, since the eutectic temperature of Fe-Si-C is lower than that of Fe-C line, and remarkable contraction of volume will occur with the progress of the sintering of Fe-xSi particles. Although the reaction between the Fe powder and C will cause solid solution, the addition of Fe powder checks the contraction of compact, since its fusing point is figher than the sintering temperature.

Title: Switching power supply circuit
Inventor: ONDA KENICHI
IPC: H02M3/28
Filed: 1980-07-11
Abstract: PURPOSE:To obtain a stable frequency of oscillation for a blocking oscillator, by adding a diode to prevent the energizing energy accumulated at a transformer from flowing into a capacitor in a blocking oscillating circuit when a main switching terminal is turned off. CONSTITUTION:When the power is applied to a switching power source, a current flows from a DC power source 12 through resistances R1 and R2, a capacitor C plus a winding Nb. Thus the capacitor C is charged. Thus a transistor (TR)16 is turned on by the current flowing between the base and the emitter of the TR16, and accordingly a voltage is induced at the winding Nb. Then the current flows to the capacitor C, the resistance R2 plus the base and emitter of the TR16 to be turned on the TR16 surely. In this case, the capacitor C is charged with the voltage decided by the voltage and the winding ratio of the source 12. At this moment, the base current of the TR16 is cut off, and the TR16 is turned off.

Title: Morpheme analyzer
Inventor: YOKOGAWA TOSHIHIKO
IPC: G06F17/27
Filed: 1989-04-13
Abstract: PURPOSE:To efficiently perform the processing of syntax analysis and following analyses by simultaneously and abbreviatedly expressing plural expressions to recognize a certain part as one word and performing correct classification to parts of speech and effectively using information of the common part. CONSTITUTION:A multiform simultaneous expression processing part 4 retrieves characters following a delimiter to search ')' and performs retrieval with the form, where '(' of the delimiter and this ')' are removed from an input character string, as the retrieval object. The start point of the retrieval object character string in this case is the character string which is the dictionary retrieval object just before '(' of the delimiter. In the case of character string 'area(s)', the dictionary is retrieved with 'area'. In the processing part 4, the dictionary is retrieved with the form of 'areas'. Both dictionary retrieval results are compared with each other to check whether original forms are the same word having the same part of speech or not. When they are the same word, information of each form is checked. OR between both forms is operated to obtain one form information, and the other information is defined as information of either of forms to obtain dictionary retrieval results.

IPC: H04L12/24
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain a remote control system for a network that can remotely control a transmitter connected in cascade (in subordinate) to other transmitters. SOLUTION: A reception section 201 at a transmission line side receives outgoing data 2A from other transmitter acting like a remote controller. A control information detection section 202 detects control information. A controller identification section 204 discriminates whether or not an identification code included in the detected control information denotes a transmitter connected to a terminal side. When this identification code indicates the transmitter connected to the terminal side, an identification code revision section 205 changes the identification code into an identification code in matching with the transmitter of the terminal side. A control command insertion separation section 203 separates the outgoing data, insets the revised identification code to the outgoing data and outputs the resulting data from a corresponding port.
