Title: Solid state optical deflector
Inventor: ISHIKAWA SACHIKO
IPC: G11B7/09
Filed: 1987-11-06
Abstract: PURPOSE:To provide the specified intensity of the deflected light within a working range by constituting the title deflector in such a manner that the intensity of the deflected light or nondeflected light is specified within the necessary angle range of an optical deflecting element. CONSTITUTION:A photodetector 27 which receives a part of the nondeflected light or the deflected light generates the current signal corresponding to the various light intensity. This signal is sent to a VCO (voltage control oscillator) 57 to change the output level of the VCO 57. Then, the voltage of the RF (radio frequency) inputted to comb-tooth electrodes 11 is changed as well and the intensity of SAW (surface acoustic wave) changes. Since the deflection efficiency of the light is thereby changed, the change is also received by the photodetector 27 and the photodetection intensity is so controlled as to as to attain a certain specified value. The intensity of the deflected light can be changed by changing the voltage to be inputted to the comb-shaped electrodes 11 and, therefore, the intensity of the deflected light maintains always the specified level even if the deflection angle changes.

Abstract: PROBLEM TO BE SOLVED: To obtain a hardened body containing uniformly dispersed bubbles by dispersing starting materials including a hydraulic material and reinforcing fibers in water, adding a water absorbing material and a thickener and/or a flocculant, also adding chips of plastic foam at an arbitrary point of time, molding the resultant slurry and carrying out curing and hardening. SOLUTION: A slurry having <=17% concentration of solid components is prepared by adding 28-55 wt.% hydraulic material such as Portland cement 3-15 wt.% ligneous or inorganic reinforcing fibers and, optionally, 28-55 wt.% fine silica powder to water. A water absorbing material such as pearlite, fired Shirasu (volcanic glass), irregular fly ash, diatomaceous earth or a crushed scrap inorganic board, a thickener such as a viscous material or a water absorbing or water-soluble polymer and an inorganic or organic flocculant are added to the slurry by 5-60 wt.%, 0.5-15 wt.% and 0.1-3 wt.%, respectively. These components prevent the flotation of chips of plastic foam such as foamed polystyrene beads and uniformly disperse the chips in the slurry.

Abstract: PROBLEM TO BE SOLVED: To simply control the reproducing speed of the voice signal with high quality without changing the phoneme and pitch by transforming N orthogonal transformation coefficient data into M data, inverse-transforming the transformed data, and making prediction synthesis based on the obtained linear/ nonlinear prediction residual.

N orthogonal transformation coefficient data obtained for each transformation unit are inputted from a transmission signal input terminal 13, and N orthogonal transformation coefficient data are transformed into M orthogonal transformation coefficient data by a data number transformation section 5. M orthogonal transformation coefficient data obtained by the data number transformation section 5 are inverse-transformed by an inverse orthogonal transformation section 6. Prediction synthesis is made by an LPC synthesizing filter 7 based on the short-term prediction residual obtained by the inverse orthogonal transformation section 6.  The reproducing speed can be simply controlled.

Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to select the time and measurement accuracy required for measurement. SOLUTION: Thermoelectromotive forces Vt1 -Vt6 outputted from thermocouple sensors 61-66 are successively amplified with a low or high gain by an amplification circuit 14 via a selector 13 and are converted into signal Sf by a V/F converter 17.
