Title: Modulator and demodulator
Inventor: SHIBATA TAKAYASU
IPC: H04L27/00
Filed: 1989-06-16
Abstract: PURPOSE:To attain the use of an inexpensive EPROM of a slow operating speed and a high speed modulation/demodulation by DSP by providing a RAM transferred in advance prior to the modulation/demodulation of a command stored in the EPROM. CONSTITUTION:Prior to modulation and demodulation, a digital signal processor(DSP) 1 transfers a command stored in an EPROM 2 through a control signal 6 to a RAM 5. Moreover, the DSP 1 stores a command sent from the EPROM 2 through a control signal 8 to the RAM 5. When the DSP 1 access the RAM 5 by the control signal 8, the RAM 5 supplies the command to the DSP 1 through a data bus 9 and the DSP 1 applies modulation/demodulation according to the command sent from the RAM 5. Thus, a high speed modulation/ demodulation is attained without using an expensive high speed EPROM and an inexpensive MODEM is obtained.

Abstract: PURPOSE:To provide an apparatus for detecting the end point of the surface treatment which can accurately detect a end point of the surface treatment of a substrate of a liquid crystal display or the like without detecting optical noise components generated at the time of the surface treatment. CONSTITUTION:A light projecting mechanism 31 takes out, by means of a filter 42a and a filter selecting mechanism 42b, the light of the wavelength enabling the detection of a reflecting light of a substrate G of a liquid crystal display with good sensitivity. The light is turned to a parallel beam by a collimator lens 45 which is then projected at right angles to the sample surface of the substrate G. The light cast to the sample surface is reflected from each surface of the substrate G to be a reflecting light. The reflecting light is condensed by an image forming lens 48 and received by a photodetecting surface Q of a photodetecting device 49. The radius D of the image forming lens 48 and the radius H of the photodetecting surface Q are set large enough to detect also a reflecting light when the sample surface of the substrate G is inclined theta. Moreover, a curtain forming mechanism 33 forms a curtain of an etching solution in the periphery of the projecting area during the measurement, thereby to prevent the pulsation of the etching solution and the entry of air bubbles.

Abstract: PURPOSE: To widen the operating voltage range of a sensor output voltage by setting the value of the resistors constituting a differential amplifier at the resistance value satisfying the derived conduction by combination of an operational amplifier.  
     CONSTITUTION: The resistor R1 is provided between an inversion input terminal T- of the operational amplifier OP1 and an output terminal T4 of the amplifier OP1 and the resistor R2 is provided between a bridge output terminal T2 and the terminal T-. The resistor R3 is provided between the bridge output terminal T1 and the non- inversion input terminal T+ of the amplifier OP1 and the resistor R4 is provided between the output terminal T3 of a reference voltage Vd and the terminal T+. The resistance values are so set that the product of the resistance values of the resistors R1 and R3 is larger than the product of the resistance values of the resistors R2 and R4. Such characteristics that the sensor output voltage Vo is nearly zero until the sensor pressure increases to a prescribed pressure and that the voltage Vo increases linearly when said pressure increases to the prescribed pressure or above are, therefore, obtd. The operating voltage range of the voltage Vo is thus widened by shifting the characteristics to the direction where the level of the voltage Vo lowers.

Title: Arithmetic load processor
Inventor: KUDO NORIMASA
IPC: G06F15/177
Filed: 1988-06-24
Abstract: PURPOSE:To shorten the processing time and to reduce the scale of a memory additional to a CPU by selecting the parallel processes carried out by plural CPUs or the decentralized processes carried out by a single CPU based on the arithmetic value and controlling the parallel processes with preference at execution. CONSTITUTION:When the arithmetic load having its arithmetic value varied by the conditions is processed, the parallel processes carried out by plural CPUs are selected for the large arithmetic value. While the decentralized processes carried out by a single CPU are selected for the small arithmetic value respectively. Then the parallel processes synchronous with each other are carried out first and each CPU performs the decentralized processes while the arithmetic loads to be processed by each CPU are evenly allocated. Thus it is possible to reduce the scale of a memory additional to the CPU and to shorten the processing time.

Abstract: PROBLEM TO BE SOLVED: To provide a fairly reliable hermetic compressor which is capable of preventing sliding portions of a piston and a cylinder from wearing down by easily forming an oil film between the sliding portions, and also sufficiently supplying oil to the sliding portions to prevent the sliding portions from running out of oil. SOLUTION: This hermetic compressor has a hermetic container, a crankshaft, an electric motor, a connecting rod 6 for transmitting driving force of the crankshaft to a piston 11 as a compressing element, and a piston pin 12 including a piston pin-oil filling port 13 communicated to an oil supplying communication passage 9 formed in the connecting rod 6, for supplying lubricating oil to sliding portions of a cylinder 10 and the piston 11.
