Title: Electrically driven press
Inventor: SHIMIZU MASATO
IPC: B30B15/18
Filed: 1986-04-04
Abstract: PURPOSE:To provide an electrically driven press which is small in size and is easy to use by providing a mechanism to convert the rotating power by a motor to linear motion to the press and commanding various functions to a ram by a central processing unit and the mechanisms associated thereto. CONSTITUTION:The motor 4 is driven by the ascending signal for setting the origin from the central processing unit 2 when a switch A on an operation panel 1 is turned on. The ram 5 is then raised by the linear motion of a screw mechanism. The central processing unit 2 stops the motor 4 when the projection 5a of the ram 5 presses a limit switch 6a to detect the ascending limit point of the ram 5. The driving is thereafter inverted; therefore, the ram 5 starts descending. The ram descends by as much as the set pulse-component stored in the central processing unit 2, when the motor 4 is stooped. The operating point is set on the side lower by the specified size than the point at which the ascending limit point of the ram operates the limit switch. A pressurized speed adjustment is thereby executed and the stable pressing operation under the slight pressure is permitted.

Title: Semiconductor integrated circuit and manufacture
Inventor: OTAKE SEIJI
IPC: H01L29/732
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To improve a semiconductor integrated circuit in current amplification factor by a method wherein a base region and an emitter region are formed through the same mask, and an active base narrow in width is obtained by lateral diffusion. SOLUTION: A base region 26 and an emitter region 27 are formed using the edge of a polysilicon layer 29 as a mask. Therefore, a distance between the leftmost diffused edges of the base region 26 and the emitter region 27 under a polysilicon layer 29 are 0.8μ long. Then, a lateral diffusion difference (0.8μm) is smaller than a depthwise diffusion difference (1.0μm), so that the collector current becomes more active in a longitudinal current path than in a lateral current, path when a bias potential is given between the base and emitter of a transistor to enable a collector current to flow. By this setup, a semiconductor integrated circuit of this constitution can be enhanced in current amplification factor.

Title: Current detection circuit
Inventor: HATAKEYAMA SATOSHI
IPC: G01R19/257
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To provide a novel current detection circuit by providing a gain adjustment function to an output voltage of a current sensor and an input voltage to an A/D converter for detecting a current to a conventional current detection circuit, thereby eliminating defects that are inherent in the conventional technology. SOLUTION: The phase current of a motor 2 is concerted into an analog voltage by a current sensor 8 and given to a current sensing section 4 via an input gain switching section 3. Conversion data of the current sensing section 4 become the feedback of the current loop of a current control section 5. The conversion data of the current sensing section 4 are also given to an input gain comparison/discrimination section 7, which indirectly monitors an input voltage given to the current sensing section 4. If the input voltage given to the current sensing section 4 reaches a full range, the input gain comparison/discrimination section 7 discriminates the decreased gain and provides a gain switching signal 73 to the input gain switching section 3.  The input gain switching section 3, receiving the gain switching signal 73, decreases the gain for the analog voltage of the current sensor 8 at a preset magnification and gives the result to the current sensing section 4. Conversely, when the input voltage to the current sensing section 4 is a prescribed value or below, the gain is increased.

Abstract: PURPOSE: To offset electromagnetic forces unnecessary for a tracking control by composing a yoke member of an inner yoke and an outer yoke and folding a tracking coil to be formed so that it wraps the inner yoke. CONSTITUTION: A yoke member 15 is comprising an inner yoke 15a and two pairs of inner yokes 15b, and a tracking coil 17 integrated into one body with a lens holder 11 fixed via elastic holding members 13 is folded and formed so as to wrap front and rear surfaces and a side face of the yokes 15b. Due to this constitution, forces in the opposite direction to each other which act on both driving devices generating rolling to the holder 11 are canceled with each other when the holder 11 is moved in the tracking direction by the magnetic forces of the coil 17 and permanent magnets 14. Therefore, the cancellation of the magnetic forces unnecessary for the tracking control allows a lens holder position to be controlled without inclination and also extends a movable range of the lens holder.
