Patent JP-H08251044-A (JP)
Title: Receiver
Inventor: SUZUKI KAZUAKI
IPC: H04B1/10
Filed: 1995-03-13
Abstract: PURPOSE: To suitably receive a digital demodulated signal depending on the phase noise characteristics of a local oscillator and the carrier-to-noise ratio of an intermediate frequency signal. CONSTITUTION: A phase noise detecting circuit 13 detects a phase noise of a 1st local oscillator 3 which determines the phase noise of the intermediate frequency signal. A C/N detecting circuit 11 detects the carrier-to-noise ratio of the intermediate frequency signal. A carrier regeneration characteristic control circuit 14 finds the gain of a variable gain DC amplifier 25 which minimizes phase jitter electric energy included in demodulated I and Q base-band signals from the phase noise and carrier-to-noise ratio of the 1st local oscillator 3, and controls the gain of the variable gain DC amplifier 25 so that the phase jitter electric energy becomes minimum. Thus, the reception device is obtained which can perform optimum reception at any time even when reception conditions are different depending upon constituent circuits of the reception device and geographic conditions.

IPC: H01L23/12
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To prevent positional deviation, when a heat sink in a ball grid array(BGA) type semiconductor device is glued using a film carrier tape. SOLUTION: When a heat sink 11 is fixed to a reinforcement plate 9 by a thermally conductive adhesive 12, a projection 15 formed on the heat sink 11 is dropped so that it touches the corner part of a device hole 17. In this manner, even if a horizontal force is applied to the heat sink 11 due to vibration or the like at transfer, the side surface of the projection 15 touches the corner part on the wall surface of the device hole 17 of the reinforcement plate 9, thus preventing the positional deviation of the heat sink 11.

Abstract: PURPOSE:To prevent the transmission efficiency on a communication line from being reduced by reading opposite slave status information when a communication error takes place, applying processing corresponding to the content of the readout slave status information so as to recover the communication error. CONSTITUTION:When, e.g. a communication controller 1a makes communication to other communication controller 1b via a communication line 5 and a communication error takes place, a communication management section 3a in the communication controller 1a being a sender reads slave status information representing the state of the communication controller 1b from a slave status information section 4b in the communication controller 1b via communication control sections 2a, 2b in the communication controllers 1a, 1b and the communication line 5 to a communication management section 3b in the communication controller 1b being a reception destination. Then the communication management section 3a applies the processing corresponding to the content of the slave status information to be read to the communication control section 2a to recover the communication error. Thus, the reduction in the transmission efficiency on the communication line 5 is prevented.

Abstract: PURPOSE:To improve the operability of a programming device by storing the selection processes of the function units at every menu display contents and then displaying successively the menus of the selected function units based on a menu display control program when a certain function unit shifts to another one. CONSTITUTION:When an operator depresses a changeover switch 43, the menu of a function unit 11 is displayed at an upper display part 42 with the function units 12 - 15 of the same level displayed at a lower display part 41 in the form of menus.

Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To easily and quickly design a circuit by using a file describing the measuring items, measuring cells, measuring conditions, etc., as an input file to generate the necessary circuit. SOLUTION: When a circuit which can evaluate the physical characteristic of a semiconductor device is designed, the necessary data are read out of a parameter file describing the prepared measuring items, measuring cells, measuring conditions, etc., (101). Then it's decided whether the measurement of an input logical level is necessary or not based on the presence or absence of the input logical level described in the test item that is written in the first line of the parameter file (102). An evaluation circuit design step is taken for measurement of the input logical level (103). A test program is generated after the subroutine of the evaluation circuit design is over (104).  Then it is decided whether the measurement of output current is necessary or not based on the presence or absence of the output current characteristic that is described in the test item written in the first line of the parameter file (105). If no output current characteristic is described, a generated circuit is described (108).

Title: Method and apparatus for continuous granulation to produce high-density detergent grain
Inventor: TANIMOTO HITOSHI
IPC: B01J2/14
Filed: 1989-03-06
Abstract: PURPOSE:To produce a high-density detergent grain and to improve the dispersibility and solubility by feeding a detergent powder on a rotating table with radial projections in a granulation chamber and granulating it by a force in the peripheral direction caused by the rotation of the rotating table in the horizontal direction. CONSTITUTION:A detergent powder for a high-density granular detergent consisting of a surface active agent, a builder, etc., is fed from a feeding hole 6A onto a rotating table 2 with radial projections 2A rotating in the horizontal direction in a granulation chamber 1. The powder receives a force in the peripheral direction caused by the projections 2A and collides against the peripheral wall face of the chamber 1 while it is rotatively moved on the rotating table 2 and returns to the rotating table 2. While this behavior is repeated, granulation is accelerated by the action of a binder and the powder is grown into a detergent grain. The formed grains fall down from the falling hole 2B and between the rotating table 2 and the inner wall of the chamber 1 and taken out of an outlet 1A to a shoot 9 by the action of a rotating blade 3. When the amt. of the grains to be treated is large, they overflow and are taken out of an outlet 1B to a shoot 8.

Abstract: PROBLEM TO BE SOLVED: To obtain a heat resistant member improved in adhesion between a metallic base material and a metallic coating layer and excellent in high temp. strength and resistance to corrosion and oxidation by forming a metallic coating layer, consisting of a lower layer composed of aggregate of coarse grains and an upper layer composed of aggregate of fine grains, onto a metallic base material. SOLUTION: A metallic coating layer 4, consisting of a lower layer composed of an aggregate layer 2 of coarse grains and an upper layer composed of an aggregate layer 3 of fine grains, is formed on a metallic base material 1 such as iron-base alloy by means of thermal spraying. If necessary, a ceramic coating layer is further formed on the above layer. As material for this metallic coating layer 4, e.g. an M-Cr-Al-Y alloy (M means Ni, Co, Fe), etc., are used. It is preferable to regulate the average grain sizes of the fine grains and the coarse grains to 1-44μm and 45-300μm, respectively, to improve corrosion resistance, oxidation resistance, and adhesion. Further, in the case where sand blasting is applied to the metallic base material 1, it is preferable to regulate surface roughness to Ra<3μm, to the extent causing no working strain.
