Patent JP-S61108204-A (JP)
Title: Electronic tuning circuit
Inventor: NISHIDA HARUKI
IPC: H03C3/22
Filed: 1984-10-31
Abstract: PURPOSE:To keep the impedance viewing a voltage supply line from a voltage varactor element high by constituting a part of the voltage supply line with a resistive element so as to make a current hardly flow when the line is coupled with a dielectric resonator. CONSTITUTION:The voltage supply circuit 12 consists of a resistive element 10 of 1/4 wavelength, a series connection of an open stub 8 of 1/4 wavelength to the element 10, and a choke connecting the connecting point between the said resistive element and the open stub 8 and a bias supply terminal. When the voltage supply line 12 and the dielectric resonator 1 are subject to magnetic field coupling as shown in one-dashed chain lines, since the coupled part is constituted with the resistive element, a current hardly flows. Then the coupling is loosened and the characteristic impedance of the voltage supply line 12 is not almost fluctuated, then high impedance is maintained. Further, a bias voltage is applied to a varactor diode 3 via the bias supply terminal, the choke 9 and the resistive element 10.

Abstract: PURPOSE:To obtain a high quality molding by enabling molding during a course of a temperature rise, by a method wherein physical quantities varying according to a temperature fall in molding cycles each are detected and a control quantity of a control device varying the said physical quantity in the next molding cycle is corrected according to the result of this detection. CONSTITUTION:The mold temperature starts gradual decrease during a course of a temperature fall, with which flowing resistance within a mold increases. Therefore, when the result of detection of the foremost position of a screw 2 has come out of an allowable range of a monitoring range in contrast with a course of a temperature rise, filling pressure in the next molding cycle is increased for correction by adding a corrective quantity from a setting instrument 27 of the corrective quantity of the filling pressure to the filling pressure of a filling pressure setting instrument 23. This correction is performed repeatedly until the result of detection falls within the monitoring range. In addition, on this occasion when a command value of the filling pressure arrives at the filling pressure L1 set up by an upper limit setting instrument of the filling pressure, operation is suspended at that point of time and molding is completed.

Filed: 1987-09-14
Abstract: PURPOSE:To improve transmission efficiency and to reduce deviation between an image and an original image, by providing a threshold value setting means to set a threshold value at a level to keep a transmission data volume almost constant at every transmission of a changed image. CONSTITUTION:Compression with high compressibility of data volume are applied on a reference image and the changed image at a control part, and they are transmitted as the coarse image data of the reference image and the changed image. Firstly, assuming that change between the reference image and the next image fetched after transmission is shown as in figure (a), the threshold value goes to the (a). Furthermore, it is assumed that certain change shown in figure (b) occurs between the image fetched at the next stage and a previous image. In such a case, a change volume goes to Va', and the Va' is less than a change volume Va, therefore, a transmission time is reduced than a constant time tc. Hereafter, the threshold value is set by the threshold value setting means so as to keep the change volume to be transmitted constant at every transmission of the changed image, and the change volume extracted by the threshold value is transmitted as the changed image.

Title: Tetrahedron dividing method
Inventor: AKIYAMA YUTAKA
IPC: G06F19/00
Filed: 1993-09-17
Abstract: PURPOSE:To eliminate a flat tetrahedron and to avoid the breakdown of Delaunay dividing by adding a new nodal point, searching a tetrahedron having the circumscribed sphere including the new nodal point, registering the tetrahedron into a search list, and performing the judgment based on the distance between the outermost triangle plane and the new nodal point. CONSTITUTION:A new nodal point is added. A tetrahedron having the circumscribed sphere including the new nodal point is searched and registered into a search list (means 1 and 2). When the distance between the outermost triangle plane and the new nodal point is less than a certain reference distance for judgment in the tetrahedron registered in the search list, the tetrahedron is omitted from the search list, and the tetrahedron registered in the search list is removed (means 3 and 4). The new nodal point and the outermost triangle of the removed tetrahedron are connected, and the tetrahedron is formed (means 5). Therefore, the tetrahedron, which is registered by the erroneous judgment caused by the error in numerical value can be omitted.

Title: Refrigerator
Inventor: DOI TAKASHI
IPC: F25D11/02
Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To enable control of temperature in a refrigerator interior in a refrigeration mode and enhance capacity of a condenser and an evaporator for a freezing chamber in a refrigeration mode by providing a refrigerant retainer means for retaining a refrigerant between a downstream side of the condenser and an upstream side of the evaporator for a refrigerating chamber. SOLUTION: In a freezing mode for cooling a freezing chamber, a refrigerant is allowed to flow to an F capillary tube 36 and an F evaporator 22. By this constitution, cold air is sent to the freezing chamber by an F fan 24 so that temperature in an interior of the freezing chamber is kept at a target temperature. In this freezing mode, when the refrigerant is allowed to flow, the refrigerant liquid gets into a state wherein the refrigerant liquid is retained in a receiver tank 40. If operation mode is changed from the freezing mode to a refrigeration mode, a self-holding valve 32 is closed and a differential valve 42 is opened. By this constitution, at the time of starting the refrigeration mode, the refrigerant liquid retained in the receiver tank 40 is first allowed to enter an R evaporator 18 through an R capillary tube 44 and then is evaporated so that starting-up is improved.

Title: Constant current drive of electrothermal transfer recorder
Inventor: TABATA YUKIO
IPC: H04N1/23
Filed: 1986-09-30
Abstract: PURPOSE:To make printing density uniform by providing a constitution in which variation occur between a first level range enabling recording at a first voltage in accordance with a third voltage level supplied to each constant current drive and a second level range allowing no recording. CONSTITUTION:A drive 5 is composed mainly of an operating amplifier (OP amp) 7, and receives an output from a character generator applied as a third voltage V1 via a gate circuit 8 with regard to a positive phase input. A first voltage V1 which is an output from OP amp 7 is connected to a recording electrode 1, and further is connected to a return electrode 2 through a recording resistor R2. This return electrode 2 is connected to an inverse phase input of the OP amp 7 and at the same time is connected to a fixed second voltage V2 via a constant voltage diode D. Printing is performed or not performed depending on variation in the first voltage V1. However, the voltage V1 increases or decreases depending on the magnitude of recording resistance R2 generated in a transfer medium 4. In this way, the voltage is adjusted so that an electric current may be supplied at constant level. This suppress variations in dot density and provides uniform density printing.
