Title: Forming method using special core for forming
Inventor: NEMOTO MASARU
IPC: B29C33/14
Filed: 1994-12-06
Abstract: PURPOSE: To prevent the deformation and the breakage of a formed product by using a core formed to uneven thickness at a part of the thickness, forming a formed mold and pressure-pouring molten metal in the mold. CONSTITUTION: In the hollow resin core 1, the thickness of a thin forming part N is thinner than the other part. The resin core 1 is arranged between an upper mold 2 and a lower mold 3 to form the mold 4 having a cavity 5. The molten metal is poured into the cavity 5 while applying the pressure to the molten metal. Even if the resin core 1 is brought into contact with the molten metal, this core is not immediately melted, but the shape at the initial stage is held, and the cast product 6 having the shape corresponding to the shape of the cavity 5 is cast. It is prevented that the cast product 6 is deformed or broken by deforming the thin forming part N when the cast product 6 cools and shrinks. The resin core 1 is melted by the preheat of the cast product 6, and made to be small and easily removed.  The formation of the one having hollow shape and under-cut shape or complicate shape can be executed.

Abstract: PURPOSE:To control occurrence of a parasitic capacity within an integrated circuit by making a device outer region in the integrated circuit to be a depletion layer and high resistance. CONSTITUTION:An impurities region with a conductive type which is opposite to an outer region is formed at a part which is adjacent to the region with a large resistance and both regions are made to be depletion layers utilizing built-in voltage generated due to difference in conductive type at both regions. That is, limitation for dD for making regions 2 and 3 to be completely depletion layers is approximately dD<=(2epsilon0epsilonr(E20-E30-DELTAE0)/qND)<1/2> and NA<+> and dA is selected to satisfy NA<+>dA=NDdD and NA<+>>>ND under this limitation. For example, when ND is 1X10<15>cm<-3> and dD is 0.5mum, the regions 2 and 3 can be made to be depletion layers completely by setting NA<+> and dA to 1X10<7>cm<-3> and 5nm, respectively. By providing the region 2, the region 3 can be made to be depletion layer and leakage current flowing through the region 3 can be prevented, thus achieving a high-performance field effect transistor. In this manner, by making the device outer region 3 in the integrated circuit to be depletion layer, a high resistance can be achieved, thus controlling occurrence of parasitic element such as parasitic impedance, etc., within the integrated circuit and achieving high performance of the integrated circuit.

IPC: G06K19/07
Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To shorten a communication time by stopping transmission of wasteful data (data having a communication error) from a reader to an external controller. SOLUTION: When an operator inserts a key 19A into a R/W device 31, the device 31 reads running data from a transponder 20 of the key 19A and gives it to a personal computer 30. In the case of this structure, the device 31 decides a communication error from the transponder 20 to the device 31, when an communication error is not detected, the device 31 sends data to the personal computer 30, and when a communication error is detected, the device 31 commands the resending of data to the transponder 20. With this, because the device 31 does not send wasteful data (data having a communication error) to the personal computer 30 any more, a communication time is reduced.

Title: Electroluminescence drive device
Inventor: YATANI YOSHIAKI
IPC: F21V23/00
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To adjust luminous brightness of an EL element a preventing an internal switch element from being destructed when the EL element is dislocated, while suppressing dispersion of the luminous brightness due to dispersion of a capacity of the EL element, in an electroluminescence(EL) drive device. SOLUTION: A comparator 15 of a control device 3 compares a voltage at B point generated by a step-up voltage of an EL element 9 with a reference voltage at C point, and discharges accumulated charge of the EL element 9 by outputting H level and switching on a switch element 10 if the voltage at B point reaches the reference voltage. A light receiving element 2 sends electric current corresponding to outside brightness and changes the reference voltage. Accordingly, a step-up peak voltage of the EL element 9 changes, and luminous brightness of the EL element 9 is adjusted. Since the luminous brightness is adjusted by changing the step-up voltage of the EL element 9, dispersion of the luminous brightness is suppressed, and also an internal switch is prevented from being destructed when the EL element is dislocated.

Filed: 1987-12-28
Abstract: PURPOSE:To lead a chip into a window frame by deciding the size of the window frame, the shift value between chips and a shift pattern from the chip size and the street size. CONSTITUTION:The presence or absence of chips 9a-9d in the window frames 12a-12d is decided from the result obtained by moving a wafer to a 1st position and recognizing it. When the presence of those chips is recognized, the position data is supplied. While the wafer is moved toward X or Y via an X-Y table for the second recognition if those chips are not set in the window frames respectively. These deciding actions are repeated. As a result, the chips 9a-9d are led into the frames 12a-12d and can be recognized with the maximum 4 times of recognition and 3 times of movement. Thus the recognizing time is shortened together with improvement of the recognizing accuracy.

Title: Photographic device
Inventor: MURATA MASATAKA
IPC: G03D9/00
Filed: 1990-11-29
Abstract: PURPOSE:To prevent the generation of dislocation by forming a separating part in such a way as to guide both heat developed sensitive material and image receiving material rectilinearly at an acute clamp angle to separate them. CONSTITUTION:Heat developed sensitive material P after the application of an image forming solvent is attached to image receiving material R so as to be subjected to developing transfer. The sensitive material P and the image receiving material R after this transfer are fed to a separating part 38 so as to be separated. In the separating part 38, the heat developed sensitive material P and the image receiving material R are both guided rectilinearly at an acute clamp angle. Accordingly, even if one material is going to be straight by rigidity at the separating terminal of the sensitive material P and image receiving material R, the force acting in the dislocating direction to the other material is small, and therefore the possibility of image dislocation is extremely small. A desirable image without image dislocation can be thereby obtained.
