Abstract: PURPOSE:To contrive to prevent dependence character of the threshold voltage upon channel width, and to enhance the characteristic and reliability of the element by a method wherein second impurity ions to form a layer of reversely conductive type from a semiconductor substrate are implanted by the quantity smaller than the implanting quantity of first impurity ions. CONSTITUTION:An oxide film 12 and a silicon nitride film 13 are formed on the P type silicon substrate 11, an oxide film 15 is formed on the whole surface, and boron (the first impurities) ions are implanted. Owing to the difference of film thickness of the oxide film 15, boron ion implanted layers 17 are formed selectively at the part excluding the silicon nitride film 13 and the neighborhood of the edge parts thereof. The oxide film 15 is removed, and arsenic (the second impurities) ions are implanted to form the arsenic ion implanted layers 18. Because the arsenic ion implanting quantity is smaller than the implanting quantity of boron ions, inversion preventing layers generated by arsenic ion implantation are formed only at the neighborhood of the edge parts of the silicon nitride film 13, impurity concentration on the silicon substrate 11 presents the condition as shown in the figure, the narrow channel effect can be suppressed, and forms the highly reliable device.

Title: Filter circuit
Inventor: KAKO YUICHI
IPC: H03H11/04
Filed: 1995-03-02
Abstract: PURPOSE: To provide an inexpensive filter circuit having a stable characteristic by setting the DC component levels of input/output signals in a filter circuit part to be the same by a bias circuit. CONSTITUTION: The output of a low pass filter 3 is connected to the output terminal T2 of IC10 through a resistor R5 . Thus, DC bias voltage generated in a bias part 4 is supplied to the output of the low pass filter 3. In such a case, DC bias voltage generated in the bias part 4 is set to become the same value as the DC component of a BS/CS(Broadcasting Satellite/Communication Satellite) video signal inputted to the low pass filter 3. Thus, DC current is prevented from flowing into the low pass filter 3 and a conventional coupling capacitor for DC component removal becomes unnecessary.

Title: Linear compressor
Inventor: AKIYAMA KAZUYUKI
IPC: F04B39/12
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To attenuate a contact load in the case where a piston is brought into contact with a cylinder so as to reduce a slide loss by movably supporting the cylinder in a direction perpendicular to a reciprocating motion owing to the contact between the piston and the cylinder in a compressor where the piston is driven in the direction of the reciprocating motion. SOLUTION: A piston 9 performs a reciprocating motion inside a cylinder 10 in association with a reciprocating motion of a movable body 21 by a permanent magnet 1 while deforming plate springs 11a, 11b in an axial direction. Where the piston 9 is moved downward, an intake valve 16 is opened to take in refrigerant gas. When the piston 9 is moved upward, the boosted refrigerant gas opens a discharge valve 17 to be discharged. In this case, the cylinder 10 can be moved in a radial direction with respect to a cylinder supporter 40 owing to a predetermined interval in a radial direction set between the cylinder 10 and the cylinder supporter 40, thus increasing a radial displacement of the piston 9. In the case where the piston 9 and the cylinder 10 are brought into contact with each other, the cylinder 10 is moved in the radial direction where a contact load is attenuated.

IPC: G01N21/84
Filed: 1978-04-12
Abstract: PURPOSE: To appreciate the quality of a two-layer insulating film making use of the dynamic scattering phenomenon of a liquid crystal.  
     CONSTITUTION: On Si substrate 1, SiO 2 2 and Si 3 N 4 3 are stacked and films 2 and 3 include defects 42 and 43 respectively. On film 3, nematic liquid-crystal film 5, transparent electrode film 6 and glass plate 7 are placed. A DC voltage is applied to substrate 1 and film 6 to observe a dynamic scattering phenomenon occurring in the liquid crystal on a defect point. With film 6 taken as a negative pole, V 02  is applied, so that only nematic liquid crystal film 5 at defect 43 will become dynamic- scattering mode occurrence region 9. Further, applying V 03  higher than V 02  makes film 5 at detect 42 into a dynamic-scattering mode region. In this way, defect positions can be found. Then, V 02  and V 03  can be calculated easily by the intrinsic electric resistances of the insulator film and nematic liquid crystal, the film thickness, and the threshold level of the nematic liquid crystal.
