Title: Aqueous emulsion composition and its production
Inventor: TANABIKI FUMIO
IPC: C08L101/02

Abstract: PURPOSE:To obtain a one-pack type cross-linkable aqueous emulsion composition having excellent storage stability and mechanical stability, capable of forming a cross-linked coating film having excellent heat resistance, water resistance, etc. by normal-temperature drying. CONSTITUTION:An oxocarboxlic acid acyl group-containing polymerizable unsaturated monomer and a polymerizable unsaturated monomer nonreactive with an oxocarboxlic acid acyl group are subjected to emulsion polymerization in an aqueous medium to produce an aqueous emulsion composition containing polymer particles to which the oxocarboxlic acid acyl group is introduced.

Title: Power-use high dielectric strength field effect transistor
Inventor: YAMAMOTO RIYUUICHIROU
IPC: H01L21/338
Filed: 1978-05-12
Abstract: PURPOSE: To secure a high dielectric strength by giving more than double thickness to the drain/source layer of the semiconductor active layer in comparison with the thickness under the gate electrode.  
     CONSTITUTION: Buffer layer 2 of a low impurity density is formed by the epitaxial growth onto semi-insulated substrate 1, and then a selective etching is given. After this, active layer 3 is epitaxial-grown and a selective etching is given again after fitting of the projections on the surface. Then electrodes 4∼6 are formed for the source, drain and gate each in the conventional way. In this way, the thickness of the buffer layer is reduced under the source/drain layer, and the thickness of the source/drain layer can be formed easily more than double the thickness of the active layer under the gate electrode. As a result, no current flows into the buffer layer, thus increasing the dielectric strength.

Title: Motor-driven curtain tassel
Inventor: UMEMURA YOICHI
IPC: A47H19/00
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To contrive a safeguard under a simple structural design. SOLUTION: A push/pull member 3 is drawn to a fixed part 21 side following the rotation of a pinion 24 in an arrow line (x) direction by a drive motor 22, and consequently, a gathering member 2 is changed from a stretched state to a curved state to bundle a curtain. If the push/pull member 3 is drawn by the distance of a push/pull stroke S to completely bundle the curtain or is pushed out to stretch the curtain, a rack has no longer the remaining teeth with which the pinion 24 is engaged, so that the pinion 24 slips resulting in the failure to apply an overload to the gathering member 2 and the drive motor 22. In this case, the elastic force of a coil spring 5 works to loosen the engagement between the rack 10 and the pinion 24. Thus the push/pull member 3 can be smoothly started.

Title: Jar effector structure in wedge grip type chuck
Inventor: KUROKI YOSHIHITO
IPC: B23B31/177
Filed: 1986-03-14
Abstract: PURPOSE:To aim at improvement in the grasping accuracy and gripping force of a chuck, by coupling each base of respective wedge parts in a wedge of a jaw effector as one body in a fork form, and increasing rigidity in these wedge parts. CONSTITUTION:A wedge 15 of a jaw effector is constituted into a fork end form where each base of two wedge parts 22 and 22 to be opposed to each other in parallel is solidly coupled together. And, in an outer position these wedges 22 are opposed, there is provided with each of section-rectangular sliding strips 25 and 25 whose upper and lower surfaces are equiangularly set up in a body and being supported by a sliding hole. A wedge 24 of the wedge part 22 of the said wedge 15 is fitted in a fitting groove of a master jaw 16, and with axial slide motion of the wedge, the master jaw slides in a direction of axial radiality whereby a work is gripped by a chuck. With this motion, the wedge part 22 tries to do rotational displacement as it receives torsional moment, but this motion is checked by the solidly coupled base 22, thus rogidity in the wedge part is increased so that gripping force of the chuck grows larger.

Title: Laser interferometer
Inventor: MIYAZAKI CHUICHI
IPC: G01B9/02
Filed: 1989-03-09
Abstract: PURPOSE:To prevent deterioration of the S/N ratio thereby to reduce factors of errors even when an incident beam is diffused at large angles by rotating an angle of a plane of polarization of said light incident upon an interferometer. CONSTITUTION:An interferometer 6 consists of a polarizing beam splitter (PBS) 6' and a quarter-wave plate 6''. A laser light incident upon the interferometer 6 is divided into two, measuring and reference lights having approximately the same strength of beams by the PBS6'. The components of the reference light and measuring light are further separated by a beam splitter 8 in front of a polarizing plate 17 and detected respectively by photodetectors 10, 11. A differential amplifier 12 detects the difference of the strength of the components and consequently a current controlling circuit 13 is controlled to that the difference becomes zero. An angle of the plane of polarization is thus rotated. Accordingly, the strength of the reference light and that of the measuring light at a photodetector 14 can be made equal to each other, whereby the interference efficiency and visibility are improved, and measuring errors are reduced.

Title: Variable nonlinear amplifying circuit
Inventor: MINAMIBATA SHIGEAKI
IPC: H03G11/08
Filed: 1980-05-02
Abstract: PURPOSE:To reduce the number of external terminals, by producing the change- over voltage of the other side by a reverse amplifying circuit to which the change- over voltage of one side is applied through the input. CONSTITUTION:The 1st change-over voltage E1 is produced by the resistances R8 R9, and the 2nd change-over voltage E2 is produced at the output side of a differential amplifier 1. When the output voltage VOUT has a relation of VOUT E1, E2 to the change-over voltages E1 and E2, the transistors Q6 and Q8 are turned off. The transistor Q6 is turned on in the case of E1<VOUT<E2; while the transistors Q6 and Q8 are turned on in the case of E1, E2<VOUT. Thus the gain VOUT/VIN of an amplifying circuit is switched successively. As a result, two change-over voltages E1 and E2 can be obtained with an external terminal to reduce the number of external parts.

Filed: 1979-05-14
Abstract: PURPOSE: To detect securely a slip at every point of a data leading-edge part by deciding whether a slip is made by measuring reproduced data of peak pulses of a fixed period at a data block leading-edge part.  
     CONSTITUTION: Data blocks written on magnetic tape 5 by write head 4 are immediately reproduced by read head 3. Then when the leading edge of the data block is detected by detecting method 1, a pulse of fixed width opens AND gate 6 of fixedperiod cycle checking method 2 and pulses corresponding to those of the fixed period of a data block leading-edge part is generated by peak-pulse generating method 15, and integrated by a primary integrating circuit 7 of method 2, whose output is compared to a set value by a primary comparing circuit 8. Once a slip is made and the pulse from method 15 decreases in period, a high-level output is generated by circuit 8 and when this high-level output continues for a fixed time, the generation of the slip is securely detected through a secondary integrating circuit 9 and comparing circuit 10 by pulses extending over every point of a data leading- edge part.
