Title: Punch device for paper
Inventor: MIYATA MORIYASU
IPC: B26F1/32
Filed: 1998-01-22
Abstract: PROBLEM TO BE SOLVED: To prevent sliding between paper or on an adhesive application surface according to pressing of a punch by regulating the movable upper limit of a push button by a housing case having an opening part which is engaged and pressed to/on a flange part formed on the lower part of the push button mounted on the upper end of a punch with spring seat. SOLUTION: At the upper end of a punch 4 which is inserted and passed against energizing of a spring 6 mounted on the upper end face within a sleeve 5, a push button 9 in which an outward flange 9f is formed at an opening end is mounted by turning the opening end downward. A recessed part formed at the inner peripheral edge of the lower end of a housing case 3 by engaging the flange 9f so as to be pressed by the peripheral edge part of an inserting/ passing hole 3a is fixed by engaging the recessed part to a projection 3c which is projectingly provided on the surrounding part of an upper side guide plate 2d of a slit 2s of a base.  As a result, because paper pieces around a punching part can be pressed and held by the peripheral edge of a die 2a and the lower end face of the sleeve 5 at the time of a punching, sliding between each of inserted and passed paper pieces or on a sticking layer of adhesive paper can be prevented.

Title: Electromagnet device
Inventor: MATSUO KENICHI
IPC: H01F7/14
Filed: 1986-01-20
Abstract: PURPOSE:To obtain uniform and superior magnetic characteristics, by composing an electromagnet device of a sectional area-different shape material having iron piece absorptive parts, a yoke in contact with end surface of a coil-wound part, and a coil wound around a yoke. CONSTITUTION:The electromagnet device is composed of a yoke 2 and a coil 9. The yoke 2 is formed by stamping a sectional area-different shape material of a plate-shaped magnetic material 20 having a projecting part 21 at its centeral part by press work and forming iron piece-absorptive parts 4 and 5 wider than the coil-wound part 2 at both end parts of the projecting coil- wound part 3. Then, the pointed-end parts of the iron-piece-attracting parts 4 and 5 are bent in near L-shapes to form the bent parts 6 and 7, and athe iron piece-attracting parts 4 and 5 are bent in the projecting directions of the coil wound parts 3, being in contact with the coil-wound part 3 at the end surfaces 3a and 3b and besides making the bent parts 6 and 7 facing each other. Because the iron piece-attracting parts are brought in contact with the end surfaces of the projecting coil-wound part, sectional area can be prevented from decreasing at the connection parts between the coil-wound part and the iron piece attracting parts.

Title: Noncontact power supply for moving object
Inventor: NISHINO SHUZO
IPC: H02J50/70
Filed: 1992-01-24
Abstract: PURPOSE:To realize stabilized power supply by fixing a coil, formed by winding a litz wire around a central protrusion of magnetic material having E-shaped cross-section, to the body such that the center of the coil is positioned in the center of a pair of induction lines and the upper and lower protrusions of the coil are positioned, respectively, above and below the induction line. CONSTITUTION:A litz wire is wound across the recesses in the upper and lower surfaces of a laterally elongated ferrite 35 having H-shaped cross-section to form a pickup coil 36. The ferrite 35 is then fixed, at the body side thereof, to the inside center of a U-shaped ferrite board 37 to constitute a magnetic member having E-shaped cross-section which is then fixed through a fixing member 38 to a pair of supporting members 39 projecting from the body toward guide rail side.

Filed: 1992-01-24
Abstract: PURPOSE:To provide a semiconductor device in which no fear exists against occurrence of breakage or cracks etc., in a mounting part of a lid and the proximity of the mounting part. CONSTITUTION:Since a lid 19 for hermetically sealing a semiconductor chip 15 mounted on a substrate 11 comprises a flexible structure part 21 formed in the proximity of a part mounted on the substrate 11, the concentration of stress in the mounting part on the substrate 11 of the lid 19 and the proximity of the mounting part is eliminated by absorption of the displacement in the flexible structure part 21 though the difference of thermal expansion caused by the increase in ambient temperature generated in the case of manufacturing, mounting or operating or the increase in temperature due to self-heating occurs between the lid 19 and the substrate 11. Thus, breakage or cracks, etc., do not probably occur in the mounting part and the proximity, and a hermetic condition can be held, and then the yield and the reliability are improved.

Abstract: PURPOSE:To facilitate the formation of a PVA of a high degree of polymerization having excellent solubility and an intrinsic viscosity above a specified value and a block character above a specified value by saponifying a polyvinyl ester of a high degree of polymerization and an intrinsic viscosity above a specified value with an acid. CONSTITUTION:A monomer such as vinyl acetate is polymerized by, e.g. low- temperature emulsion polymerization to produce a polyvinyl ester of a high degree of polymerization and an intrinsic viscosity >=1.4dl/g. This polymer is dissolved in a solvent (e.g. 1,4-dioxane) and saponified with an acidic catalyst (e.g. benzenesulfonic acid) in the presence of water. In this way, a PVA having a high degree of polymerization, an intrinsic viscosity >=1.4dl/g, a block character >=0.55 and excellent solubility and suited for the production of a high- strength fiber or the like can be obtained. The intrinsic viscosity is defined as a value determined on polyvinyl acetate prepared by reacetylating the polymer in acetone at 30 deg.C.

Title: Drive circuit of actuator
Inventor: NOMURA TADASHI
IPC: H01L41/083
Filed: 1985-01-25
Abstract: PURPOSE:To eliminate hysteresis characteristic for the characteristic of an output displacement with respect to an input signal by substantially unitarily determining the variation of a laminated piezoelectric element. CONSTITUTION:The output of a current integrator 8 corresponds to a charge amount applied to a laminated piezoelectric element 6 in a zone of position detecting lower limit frequency or higher corresponding to the leakage time constant. Since the hysteresis in the relationship between the charge amount applied to the element 6 and the displacement of the element 6 is extremely small, the output of a current integrator 8 corresponds substantially to the displacement of the element 6 in a zone of the position detecting lower limit frequency or higher. The drive lower limit frequency corresponding to the time constant of a high pass filter 1 is larger than the time constant of the filter 1 at the leakage time constant of the integrator 8, it is higher than the position detecting lower limit frequency. Accordingly, the integrator 8 operates faithfully in the output signal of the filter 1.

Abstract: PURPOSE: To obtain a solid state pickup device featuring a high S/N and high sensitivity by forming the hetero-junction which features an extremely high sensitivity and a reduced amount of the dark current on the charge transfer type solid state element on the semiconductor substrate.  
     CONSTITUTION: The n + -type region 11 is formed on p-type semiconductor substrate 10, and the diode is provided. Potential barrier 12 blocks the injection of the electron from region 11 in case CCD is operating at the p + -type region. Now if the light enters from electrode 21, the electron positive hole pair is grown by photoconductor 19 which is composed of (Zn 1-x Cd x Te) 1-y (In 2 Te 3 ) 7  and features an extremely high sensitivity and a reduced amount of the dark current. The hole pair arrive at electrode 18 and 21 each to lower the potential of electrode 18. Furthermore, reading pulse VCH is applied to 1st gate electrode 14, and thus the surface potential under electrode 14 rises up. And then the electron is injected to region 13 from region 11 and then supplied to combined capacity CB which is formed with substrate 10 and electrode 14, and the total amount of the transferred charge corresponds to the luminous intensity of the incident rays. As a result, a solid state pickup device can be obtained with a high S/N and high sensitivity.
