Title: Vibration transmission plate for coordinate input
Inventor: KAWAKAMI TATSURO
IPC: G06F3/0488
Filed: 1992-01-24
Abstract: PURPOSE:To improve the detection precision of a vibration input position by forming the vibration transmission plate in two-layered structure of an input layer and a vibration propagation layer, using glass for the vibration propagation layer, and setting the bending elastic modulus of the input layer within a specific value range. CONSTITUTION:The vibration transmission plate consists of the input layer 8B and vibration propagation layer 8. Vibration generated by a vibration input pen 3 is made incident on the vibration transmission plate, and measured and processed to calculate the position coordinates of the vibration input pen 3. The glass plate is used for the vibration propagation layer and the bending elastic modulus of the input layer is limited to a range of 180-720kgf/mm<2> to reduce the phase delay of a vibration wave generated depending upon the tilt angle theta of the vibration input pen 3, thereby making a position detection error small. The vibration transmission plate is composed of at least three layers, which are made to abut on each other by adhesion; and then a right-angle directional vibration component is sent to the next layer and the asymmetry of vibration transmission mode caused depending upon the tilt angle theta of the vibration input pen is reduced.

Title: Processing method for silver complex salt diffusion transfer
Inventor: TSUBAKII YASUO
IPC: G03C8/06
Filed: 1985-01-23
Abstract: PURPOSE:To reduce the dependency of a processing soln. on processing conditions and to provide high suitability to running processing by making the concn. of inorg. salts in a replenisher higher than the concn. of inorg. salts in the processing soln. and adding aminoalcohols each having a specified pKa value to the processing soln. and the replenisher. CONSTITUTION:Amino-alcohol having <9 pKa value in 50wt% aqueous ethanol soln. at 25 deg.C is added to a processing soln. for running processing, and amino- alcohol having >=9 pKa value is added to a replenisher to be supplied to the processing soln. In the processing soln. for silver complex salt diffusion transfer, the activity of the amino-alcohol having >=9 pKa value is chiefly utilized while the soln. is relatively fresh, and the activity of the amino-alcohol having <9 pKa value is chiefly utilized when the pH of the processing soln. is reduced by running processing, so satisfactory processing is carried out. Since sufficient alkalinity can be ensured by combining the amino-alcohols having different pKa values, the amount of an inorg. alkali agent used can be reduced. Thus, running processing can be carried out for a long period while the characteristics of the fresh processing soln. are maintained.

Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To maintain an excellent barrier properties in a high temperature atmosphere by coating at least one face of a biaxially drawn nylon film with a specified amt. of polyvinylidene polymer and providing a specified thickness of aluminum-metallizing thin film on the coated face or an uncoated face. SOLUTION: At least one face of a biaxially drawn nylon film is coated with an aqueous dispersion or an org. solvent soln. of polyvinylidene polymer and dried and heat-treated to form a film with an amt. of 0.1-5.0g/m<2> . When the amt. is less than this range, it becomes difficult to hold enough barrier properties even at a high temp. and when it is greater than this range, there exist disadvantages in operatability and the cost. An aluminum-metallizing thin film with a thickness of 300-700Å is formed on the coated face or an uncoated face of the film coated with the polyvinylidene polymer. When the thickness is smaller than this range, barrier properties is not sufficient and light reflective properties is bad and when it is larger than this range, enough laminating strength is not obtd.

Filed: 1981-01-30
Abstract: PURPOSE:To decrease reactive power and to reduce the running cost of a press machine or the like by detecting the accumulated energy of a flywheel, and controlling the supply voltage of an electric motor in accordance with the energy. CONSTITUTION:While sufficient energy is accumulated in a flywheel 1, the slip of an electric motor 2 is the same as the slip under no load, and energy is released from the flywheel 2. With a decrease in the rotating speed of the flywheel 2, the slip of the motor 2 increases. If this slip is detected with a detector 3, the release load energy is known with a reference setter 7 and an operator 6. Next, the primary supply power of the motor 2 is controlled by a thyristor device 4 in accordance with the magnitude of the release load energy, whereby reactive power is suppressed.

IPC: C02F1/58
Filed: 1979-02-05
Abstract: PURPOSE: To reduce the amount of sludge generated by purifying treatment as well as precipitate and remove effectively fluorine present in waste water in form of calcium fluoride.  
     CONSTITUTION: An acid waste water containing fluorine is mixed with a water- soluble calcium salt, e.g., calcium chloride, etc., and then mixed with slaked lime to regulate its pH to 2W6 to form calcium fluoride.

Filed: 1990-01-23
Abstract: PURPOSE:To reduce the reproduced read error by outputting N-th read data a specific component of the sampling frequency for at the time of reproducing ahead of the output time of operation results. CONSTITUTION:When the decimal part of the result of addition between the increment value of the read address of a waveform memory corresponding to 1/2fs (fs is the sampling period) and the preceding read address is smaller than 0.25 or larger than 0.75 in the sampling after the end of the processing of sampling NoS-2 for reproducing, the integer part of the read address of the addition result is used to read out waveform data. The read address of the waveform memory is not always designated by the fixed sampling period, but N-number of opportunities of sampling are made by periods obtained by equally dividing the sampling period into N and the point which is not distant from the integer part is designated as the read address of the waveform memory. Thus, sampling data at the time of reproducing is not remote from the analog waveform of original sounds, that is, the error is reduced.

Filed: 1990-01-22
Abstract: PURPOSE:To achieve stability of operation over a long term by making a groove for discharging abrasion powder, produced through sliding of first and second resilient bodies, in the sliding face of at least one of them thereby removing abrasion powder from the sliding face of an ultrasonic motor. CONSTITUTION:Upon application of an AC electrical signal of predetermined frequency onto an ultrasonic oscillator 11, the ultrasonic oscillator 11 repeats longitudinal and bending oscillations to produce a driving force. The shape of the ultrasonic oscillator 11 varies with time and the right end of a drive unit 32 contacts with a rail 34 at the time of contract of longitudinal oscillation. When a movable unit 32 contacts with the rail 34, it is subjected to driving force and produces thrust. Abrasion powder is produced on the sliding face when the moving unit 11 is driven continuously, but since the abrasion powder is collected in a groove 40 abrupt proceeding of abrasion can be prevented.

Filed: 1990-01-23
Abstract: PURPOSE:To reduce the time and the cost necessary for mounting, and improve the reliability of bump electrodes and electrode terminals to be connected with the electronic circuit of a semiconductor element, by forming the bump electrodes having height difference and recessed parts accepting the tip parts of the bump electrodes. CONSTITUTION:Bump electrodes 2a, 26 are formed on a semiconductor element 1. The height of the electrode 2a is larger than that of the electrode 2b. Electrode terminals 5a, 5b are formed on a mounting board 3, so as to correspond with the electrodes 2a, 26. On the surface of the terminal 5a, a recessed part 4 accepting at least the tip part of the electrode 2a is formed so as to become deep gradually from the outer peripheral part toward the center part. Hence the electrodes 2a, 2b can be highly precisely aligned with the terminals 5 only by pressing the element 1 lightly against the board 3. Since the height of the electrode 2a is different from that of the electrode 2b, reduction of contact is enabled during alignment, thereby decreasing damages of each electrode and each terminal. Hence the time and the cost necessary for mounting can be reduced, and the reliability of the electrode terminals and the the bump electrodes can be improved.
