Filed: 1989-02-01
Abstract: PURPOSE: To produce microemulsions that produce very thin coherent elastomer films by mixing colloidal silica and certain tin-containing catalyst to precursor emulsion containing cyclo polydiorganosiloxane in polymerization medium.  
     CONSTITUTION: A transparent stable microemulsion that contains small drops of polydiorganosiloxane with a size of 0.15μ and a surfactant in a weight ratio of 0.15-0.65 is produced by adding precursor emulsion comprising cyclo polydiorganosiloxane, the surfactant and water to polymerization medium comprising water and an effective quantity of a polymerization catalyst while mixing the precursor emulsion. Then 5-30 pts.wt. of colloidal silica based on 100 pts.wt. of the siloxane and 1-5 pts.wt. of dialkyltin dicarbokylate catalyst based on the microemulsion are mixed to the microemulsion to produce the objective microemulsion that produces coherent elastomer films in thickness of 0.4 μby removing water at room temperatures.

Title: Automatic controller for optical output
Inventor: YOSHIKAWA SEIJI
IPC: G11B7/1263
Filed: 1983-02-10
Abstract: PURPOSE:To make a system stabilize by providing a means which subtracts the component of (mean value of waveform factor of modulated signal) X (set value of peak power in modulation mode) which is contained in a light quantity detection signal when the optical output is modulated. CONSTITUTION:The modulated signal of a terminal 11 (shown in a figure A) is transmitted through an LPF 30 to average the waveform factor. Thus a signal having a waveform shown in a figure B is obtained. This signal is applied as an input (m) of an analog multiplier 15 and also applied to the output voltage of a power supply 16 for setting of peak power in modulation mode in the form of an input (n). Therefore a waveform (mXn) shown in a figure C is delivered from the multiplier 15 and applied to one of plus inputs of a comparator 13. Thus an output (C+D)-E is obtained from the comparator 13, and the system disturbance due to the waveform C is compensated. If no coincidence is obtained between the output of a light emitting element 1 which is increased by a variable current source 9 and the peak power value set in a modulation mode, (C+D)-E=0 is not satisfied. Therefore the proportion is controlled by an efficiency control circuit 19 between said set value and the value of th source 9. Thus the coincidence is obtained between the set value and the detection output of a photodetector 4.

Title: Controller for recording light quantity of optical disk device
Inventor: MORI KUNITAKA
IPC: G11B7/125
Filed: 1985-02-06
Abstract: PURPOSE:To ensure the recording with uniform quality by providing an averaging means for output of a monitor sensor and a detection means which detects the difference between the output level of the averaging means and a prescribed level and controlling the drive current of a light source in response to the output of said detection means. CONSTITUTION:The output of a monitor sensor 4 set into a position close to a laser diode 1 is averaged by an averaging means consisting of an LPF 5 and an operational amplifier 6. It is decided by a comparator 9 whether the averaged output (c) is less than the target values (Vh, Vl) or not. If the output (c) exceeds the target values, a counter 11 performs subtraction. While the counter 11 performs addition when the output (c) is less than the target values. For the counting timing, a timer 12 sends the timing signal to a counting gate 10 based on a signal (a) so that the counting action is started at a time point when the output (c) is stabilized after a writing action is started. The count value is converted into analog signals by a D/A converter 13 for control of a recording current source 3.

Abstract: PROBLEM TO BE SOLVED: To simply reduce noise even with respect to a plurality of noise sources without requiring a sound prescribing means by forming the housing of an image forming apparatus into a structure leaving a paper discharging opening part and set to a state substantially closed from an aspect of a sound field and arranging an electroacoustic converter in the vicinity of the paper discharging opening part. SOLUTION: Various noises are generated from respective drive mechanisms in a housing 1 accompanied by the start of printing operation but, since the housing 1 has a hermetically sealed structure from an aspect of a sound field except the opening part of a paper discharge part 2, the greater part of noise is radially emitted to the outside only from the housing opening part of the paper discharge part 2.  Therefore, a control speaker 32 generating a control sound is provided extremely in close vicinity to the paper discharge part 2 as a sound arresting mechanism and a control sound same to the noise emitted from the respective drive mechanisms in the apparatus main body in magnitude but having a waveform exactly opposite to that of the noise in phase is outputted from the control speaker 32 to effectively arrest or reduce the noise emitted from the paper discharge part 2 to the three-dimensional space outside the apparatus.

Filed: 1990-01-30
Abstract: PURPOSE:To increase resistance to mechanical and electrical abrasion and improve the electric conductivity of the title commutator by employing a dispersion-type reinforced copper alloy for the commutator of a motor for an automotive fuel pump. CONSTITUTION:The commutator of a motor for an automotive fuel pump is formed of an alumina dispersion-type reinforced copper alloy. The alumina dispersion-type reinforced copper alloy, containing 1.0weight% of Al2O3, is employed to effect the operation test of the same and the reduction of the amount of abrasion of about 80% is confirmed compared with the material of the commutator so far. The physical property i of the dispersion-type reinforced copper alloy is prominent in a hardness and a tensile strength compared with the material used so far. The deterioration of mechanical properties at a high temperature is small compared with the material so far. When the content of alumina is less than 0.1weight% of Al2O3, sufficient hardness and tensile strength can not be obtained but when it is more than 0.1weight%, the deterioration of electric conductivity is large and, therefore, the dispersion-type reinforced copper alloy having the composition specified above is optimum for the material of the commutator.

Neither a lead frame nor a substrate is used, thus reducing time for forming a semiconductor device and hence reducing cost. Also, the elimination of the lead frame and the substrate reduces the thickness of the package by that amount and hence increases the number of pins.
