Abstract: PURPOSE: To obtain the picture of desired white color temperature with good  quality, without disturbing the process, by changing at least one electrode size or  the size between electrodes for the electron gun constituent, in altering the white  color temperature of the color receiving tube.  
     CONSTITUTION: In the electron gun in which the current ratio of each electron gun is changed and the burden is increased, constituting the electron gun, by changing the white color temperature, to suppress the current causing aberration, the electrode plate thickness t 1  of the first grid 3 is made thinner than other electron gun. The diameter of electron beam can be made equal even with increased operation range of the electron gun, by decreasing the hole diameter G 1 ϕ of electron beam passing hole or increasing the distance d 34  between the first grid 3 and the second grid 4. Or, by changing the distance d 23  between the first grid 3 and the cathode 2 in comparison with other electron guns, the operation voltage of the electron gun is changed and it can be equal approximately with other electron gun current. With those methods, failure or hallow in the shape of electron beam can not be caused to obtain desired color temperature.

Title: Air-fuel ratio control device for engine
Inventor: NAKAJIMA YUKI
IPC: F02D41/12
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To apply a wall flow correction amount on a optimum high frequency component during fuel recovery accompanied by switching of a target fuel-air ratio equivalent for a cylinder where fuel is cut. SOLUTION: In this device, for a cylinder where fuel is cut, an adhesion amount decreased during cut of fuel is predicted for each cylinder by a predicting means 44. For a cylinder where fuel is recovered, during recovery of fuel, a value obtained by multiplying a difference between an adhesion amount Mf and an adhesion amount Mfn for each cylinder by a deal ratio Kmf is set as a value one cycle before the adhesion speed for each cylinder by a setting means 46. From a difference between an adhesion speed Vmf and a value one cycle before the adhesion speed and a reply gain A of a low frequency component, a wall flow correction amount Chosn<1> for a high frequency component is computed by a computing means 39.  In this way, by computing the Chosn<1> during recovery of fuel by considering a cylinderwise fuel cut, inclination to the lean side of an air-fuel ratio due to shortage in the Chosn<1> is prevented from occurring even when fuel recovery accompanied with switching of a target fuel-air ratio equivalent is performed.

Abstract: PURPOSE:To highly precisely detect the weight of resin fill in a cavity part by finding a specific volume value based on the relational expression of a resin pressure value and a specific volume value, which is found in advance, after obtaining a resin pressure value of a screw, and detecting the weight of a plasticizing synthetic resin fill in the cavity part of a mold by computation. CONSTITUTION:When a predetermined pressing force is applied to a screw 8 by injection pistons 14, a plasticizing synthetic resin is compressed, and the screw 8 moves, while keeping a balance with the pressing force, up to a point where the reaction force of the compressed resin is balanced with the pressing force before the screw is stopped. The pressure value of the resin at this first stopping position is detected by a screw pressing force detector 20, and the detected value is given to an operation unit 19. Then, upon completion of pressure maintenance after the resin is injected and packed into the cavity part 7 of a mold 1, a predetermined pressing force is applied to the screw 8, and the screw 8 advances and stops. The pressure value of the resin at this second stopping position is detected, and the detected value is given to the operation unit 19. Then, the operation unit 19 finds the specific volume values of the resin at the first and second stopping positions of the screw 8 according to a PVT relational expression found in advance, thus the weight G' of the resin filled in the cavity part 7 is computed.

Filed: 1994-04-01
Abstract: PURPOSE:To obtain an efficient bus cycle by making the wait time from the input of an active command, inputted to a synchronous DRAM, to actual access to data, overlap with a snoop process. CONSTITUTION:When a bus master 12 accesses a main storage device consisting of the synchronous DRAM 3, since the start address of a write-back cycle generated as the result of the snoop process corresponding to the access and an address that the bus master 12 tries to access, are within a range of the block size of a cache memory 2, address information is the same. And, since a row address input, i.e., the active command becomes the same, when access from the bus master 12 is performed, the active command can be omitted by inputting the active command at the stage of the snoop process. The efficient bus cycle wherein the time interval from the input of the row address to the input of a column address overlaps with the snoop process of the cache is obtained.

Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To select ON/OFF of attraction and allow reliable attachment/removal extremely easily by changing a rotation angle of a permanent magnet provided on an attaching/removing mechanism by a handle. SOLUTION: A pair of attaching/removing mechanisms 5 incorporating a permanent magnet 20 are provided on a main body. The permanent magnet 20 of each of the mechanisms 5 is rotated by handles 6 rotatably provided at both ends of the body. Rotating the handle 6 changes a position of the permanent magnet 20, so that the body can be attracted to or released from a cage member 1. That is, the permanent magnet 20 exhibiting a flat plane shape having north and south poles at both ends is positioned in a gap 22 of a yoke 21, and when a magnetic flux 23 passes through the cage member 1, attraction is ON. When the magnetic flux 23 does not pass through the member 1, attraction is OFF. Thus it is possible to select attraction or release only with a rotation angle of the permanent magnet.
