IPC: H03M3/04
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To minimize voice quality degradation and to reduce an information amount in adaptive predictive encoding. SOLUTION: Voice signals added to an encoder input terminal 10 are supplied to an adaptive predictive encoder 1 and a pitch extraction device 3. The pitch extraction device 3 extracts pitch information composed of the presence/absence of a pitch, a pitch cycle, a pitch gain, a pitch section number and a non-pitch section length from the voice signals and supplies it to an encoding execution judgement device 2 and an encoder 4.

Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To minimize the ratio of leakage loss to motor loss against theoretical compression work of a refrigerant compressor and enhance the compression performance and execute fine control near room temperature by increasing the minimum value of a specified operation frequency zone during steady state operation except for starting time. SOLUTION: Except for starting time, a steady state operation frequency is transferred to a higher frequency side on the whole where a refrigerant compressor 100 is adapted to reduce its stroke volume so as to comply with a double-increased speed operation, thereby reducing the rate of leakage loss to theoretical compression work and enhancing dramatically the performance of the compressor 100 during a minimum frequency operation. The drive torque of a motor required for the compression of working refrigerant during the same refrigerating capacity is favorably half since the frequency is boubled. The operation at a low frequency less than a commercial power frequency, at which breakdown torque, is dramatically reduced, is not executed with in a steady state operation range.  Therefore, motor loss is not generated and iron loss is reduced so that motor efficiency is enhanced and the performance of the compressor and period energy consumption efficiency of a refrigeration cycle device is improved, which makes it possible to execute sophisticated control near room temperature.

Filed: 1986-08-05
Abstract: PURPOSE:To improve sliding characteristic and attraction resistance and to assure a long life by forming grooves having a specific depth and width at >=1 pieces per 10mum concentrically to the surface of a hard underlying film. CONSTITUTION:Liquid is held in the concentrical grooves if the many grooves are formed on the surface of the above-mentioned film. The dissipation of the liquid by centrifugal force is then decreased and the deterioration in the sliding characteristic is obviated. However, if the grooves are as deep as >=0.1mum, the magnetic field of a head does not reach the magnetic film in the bottom and the overwrite characteristic of the output decreases to >=30dB. Such depth is, therefore, undesirable. The effect of the grooves is low if the grooves is as shallow as <=0.01mum. The width of the grooves is stipulated to >=0.1mum and <=1Xm from the size of abrasive grains for working. The effect of decreasing the attraction characteristic by the decrease in the actual contact area between the disk and the head is obtd. if the concentrical grooves are formed to the distribution density of at least one piece per 10mum as the width of the slider is about 0.1-0.8mm.

Filed: 1988-07-22
Abstract: PURPOSE:To measure the surface roughness of an object of measurement with high accuracy by setting emitted light beams in optical paths of regularly reflected light beams when the object is irradiated with light beams and diffuse reflected light beams in plural directions. CONSTITUTION:The light beams from a light source 1 is projected on the surface of a steel plate P at an angle theta and the quantity of the regularly reflected light beams are detected by a radiometer 3 provided in the conjugate direction with the light source 1. Further, the quantities of the diffuse reflected light beams in the different directions are detected by radiometers 4, 5, and 6 arranged on a spherical surface having its center at the irradiation point O of the steel plate P. Consequently, the regular reflection factor of the steel plate P as the object of measurement and the diffuse reflection factors in the directions are found by using the radiant energy values measured by the radiometers 3-6 and radiant energy values corresponding to environmental temperature measured values at positions corresponding to the installation positions of the radiometers 3-6. The surface roughness of the steel plate P is calculated from a predetermined expression based upon those reflection factors. Thus, the surface roughness is accurately measured without being affected by the material and surface properties of the steel plate and variation in ambient temperature.
