Title: Message recording set for telephone
Inventor: YAMAMOTO OSAMU
IPC: H04M11/10
Filed: 1988-12-22
Abstract: PURPOSE:To save memory capacity by starting a recording and reproducing circuit with closing of a telephone line so as to apply endless message recording by one of recording blocks. CONSTITUTION:When a handset is lifted up, hook switches 2a, 2b are operated and a speech line loop is formed in a route of a telephone set terminal 1, hook switch 2a and a telephone set circuit 3 and a telephone line. Simultaneously, a recording and reproducing circuit 4 is started. A recording and reproducing section 4a receives a recording signal from the telephone set circuit 3 to apply data conversion to be stored in a semiconductor memory and stored in the semiconductor memory 4b. When a recording control switch 6 is not depressed down by the hook-off, speech recording is started and the data are written sequentially from the address 00000. If the recording time exceeds 16sec while the switch 6 is not depressed, the address is restored from the address 4FFFF and the recording is applied repetitively from the address 00000.

Filed: 1992-12-01
Abstract: PURPOSE:To invert the input voltage and boost it so as to get inverse output voltage by so constituting this DC-DC converter as to connect one end of a series circuit, where the second switch of each unit circuit is connected in series, to load through an output switch. CONSTITUTION:Switches S11 and S12 are turned on. Next, switches S21 and S22 and a switch S13 are turned on after the tuning-on of the switches S11 and S12. Hereby, a capacitor C2 is charged with the voltage of 2E where the interterminal voltage E of a capacitor C1 is loaded on the DC voltage E of a DC power source A. Next, when switches S13, S23, S33,..., Sn-1, 3, and Sn are turned on, the capacitor Cn of output is charged by the voltage -(2<n-2>-1) E of the sum to the interterminal voltage of the capacitors C1, C2,..., and Cn-1, and the interterminal voltage of the capacitor Cn for output at this time becomes -(2<n-2>-1) E. By repeating this, inverse output voltage, where the DC voltage is being input voltage is boosted, can be gotten.

Title: Probing method
Inventor: ABE YUICHI
IPC: G01R31/28
Filed: 1987-12-18
Abstract: PURPOSE:To automatize adjustment of a contacting pressure of a probing needle, by controlling said contacting pressure through detection thereof from traces of said probing needle. CONSTITUTION:A contacting pressure of a probing needle is reflected on the size of traces of the probing needle. The size of the traces can be known by calculating the area of the whole region indicated by an address '1' indicative of the presence of traces. The size of the traces is also found as to how much it is larger or smaller than a reference by comparing the traces with data of traces of a predetermined size stored in a ROM 36. The contacting pressure can be adjusted by changing the stopping position of a platform 2 in a Z direction. In other words, since the contacting pressure is determined by an over-driving amount of the platform 2 after a probing needle 30 is brought into contact with a chip, it can be adjusted by reducing the over-driving amount of the platform if the traces are larger than the referential size.

IPC: D05B57/20
Filed: 1994-12-26
Abstract: PURPOSE: To provide a magnetic retainer simple in structure, easy to install and adjust gap size dispersion, and reliable in muffling shock noises. CONSTITUTION: An inner magnet 13 is fixed at a specified spot on the outer circumference of a bobbin case holder 7, and an outer magnet 19 is fixed on the sewing machine main body with a gap K1 provided between them for the needle thread to go through.

Filed: 1987-12-22
Abstract: PURPOSE: To obtain a inexpensive and convenient pen of a liquid writing instrument in which abrasion resistance, elasticity, bending strength and writing touch are enhanced while prolonging the lifetime by molding a mixed composition containing a thermoplastic liquid crystal polymer. CONSTITUTION: The pen of a liquid writing instrument is produced by molding a mixed composition containing a thermoplastic liquid crystal polymer. The thermoplastic liquid crystal polymer is an aromatic polyester based resin produced by copolymerizing one or more than one kind of terephthalic acid, biphenyl and polyethylene terephthalate with parahydroxy benzoic acid or paraacetoxy benzoic acid. A good effect can be attained for utilizing the rigidity and the orientation of liquid crystal polymer when the content thereof is set at 20 wt.% or above in the mixed composition.

Title: Steering damper
Inventor: SATO YUTAKA
IPC: B62D1/16
Filed: 1988-12-22
Abstract: PURPOSE:To prevent any disturbance from being transmitted to a handwheel as well as to make improvements in steering stability by interrupting an oil passage interconnecting plural numbers of oil chambers at a time when the disturbance is added to a tire and each turning of the handwheel and this tire has come to the reverse direction. CONSTITUTION:When a handwheel is steered to the right, by way of example, a spool 25 is moved in an E direction via a rod 33, so that each of ring oil grooves 26, 27 of this spool 25 is interconnected to respective oil holes 21, 22. When the handwheel is turned to more than a constant angle, a piston rod 14 is moved in an F direction, so that a hydraulic fluid in an oil chamber S1 flows into an oil chamber S2, whereby handwheel rotation becomes lighter. On the other hand, when right disturbance acts on a tire, by way of example, the piston rod 14 moves in an F direction. If so, the hydraulic fluid in the oil chamber S2 flows into an oil passage 30, and a check ball 31 closes this oil passage 30, so that the piston rod 14 comes into a state of being locked. With this constitution, transmission of the disturbance against a handwheel side member is prevented from occurring.

Title: Production of phase difference film
Inventor: MORIKAWA MICHITAKA
IPC: G02F1/1335
Filed: 1992-12-04
Abstract: PURPOSE:To decrease the dependence of retardation on an angle by shrinking a stretched thermoplastic resin film or sheet in a stretching axis direction while suppressing the elongation in the directions parallel with the plane of the film or sheet perpendicular to the stretching axis at the time of thermally relieving the above- mentioned film or sheet. CONSTITUTION:The stretched thermoplastic film or sheet shrinks in a stretching direction when this film or sheet is thermally relieved in a non-restrained state at the temp. above the glass transition temp. of the thermoplastic resin film or sheet. The film or sheet necks in and shrinks in the directions parallel with the plane of the film or sheet and perpendicular to the stretching axis at the time of the stretching and, therefore, the film or sheet tends to elongate in the directions parallel with the plane of the film or sheet and perpendicular to the stretching axis at the time of thermal relieving. The film or sheet shrinks in the stretching axis direction and its thickness increases and in addition, the dependence of the retardation on the angle is ameliorated when the elongation in the directions parallel with the plane of the film or sheet and perpendicular to the stretching axis is suppressed to the length shorter than the length at which the film or sheet can elongate in the non-restrained state at the time of thermally relieving.

IPC: H04N7/26
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To reduce a calculation time required for decoding an image while keeping a high image quality by correcting processes of inverse cosine transform and inverse weighting so as to process only image information used for display. SOLUTION: Applications of an inverse weighting(IW) 135 and an inverse cosine transform (IDCT) 140 are combined to obtain one function. As a means of decoding an image of 1/4 size, a horizontal 4-point IW/ICDT processing is applied to coefficients up to a 4th column from a side of a first 4 rows corresponding to lower coefficients in a 8×8 matrix of transformation coefficients being part of a video frame. A vertical 8-point IW/IDCT processing is applied to all coefficients of first 4 columns where the coefficients up to a 4th row from a side of each column corresponding to a high frequency are set to zero.  In the case that an input block consists of two 4×8 matrices consisting of sum and difference coefficients, the horizontal 4-point processing is applied to each row of each matrix and the vertical 4-point processing is applies to the sum of sum coefficients and difference coefficients.
