Title: Picture processing unit
Inventor: HIRATSUKA SEIICHIRO
IPC: H04N1/23
Filed: 1989-02-28
Abstract: PURPOSE:To stably reproduce a picture with excellent gradation expression and high quality by amplifying additively a multi-value analog picture signal and a vibrating waveform, using the added signal to drive a laser light source. CONSTITUTION:A digital picture data given externally is converted into a multi- value analog picture signal by a D/A converter 11. The picture signal is fed to one input terminal of a summing amplifier 13. Then a vibration waveform generated by a vibrating waveform generating circuit 12 is fed to the other input terminal of the summing amplifier 13. Thus, the two signals applied to the summing amplifier 13 are added and portions over a prescribed value or over and a prescribed value or below are cut off. Thus, the resulting signal is equivalent to the combined signals subject to luminance modulation and pulse width modulation and a picture with high quality in which even an intermediate tone is reproduced accurately is reproduced.

Title: Floating method for nonmetallic inclusion in intermediate vessel
Inventor: IKEHARA YASUMASA
IPC: B22D11/117
Filed: 1980-04-12
Abstract: PURPOSE: To generate bypass flow in molten steel and allow non metallic inclusions to float adequately by discharging the molten metal in a ladle to the wall side in an intermediate vessel by the use of a long nozzle closed in the bottom part.  
     CONSTITUTION: The molten metal in a ladle 1 flows out from a long nozzle 7-1 which is closed in the bottom part and has one discharge hole 8. This molten metal collides against the short side wall 9 of an intermediate vessel 2-1. After the molten steel is suppressed of dynamic pressure by this, it bypasses along each long side wall 10 at slow speeds and arrives at a nozzle 6, after which it is poured into a mold 3. By this mechanism, sufficient molten steel residence time is obtained, and the rate of floating of nonmetallic inclusions is increased.

In this case, the control valve 17 is driven by an actuator 19 through a link work 18, and this actuator 19 is controlled by a control circuit 20. Then, intake air temperature detected by a temperature sensor 23, and others are input in the control circuit 20, for controlling the control valve 17 to the preset desired opening. At this time, the control is performed as compensating the opening of the control valve 17 toward the valve-closing side, as the temperature of the intake air becomes lower.

Filed: 1989-03-02
Abstract: PURPOSE:To effectively obtain electric power with a small number of components by fixing one end of a cord to the inside of a floating body via a spring means, and driving a power generating means with the relative movement of the cord and the floating body. CONSTITUTION:When a floating body 1 is thrown on the sea surface, the floating body 1 is floated. A weight 5 sinks below the sea surface and is kept stationary when the tension of a spring 2 and the gravity of the weight 5 are balanced. When the floating body 1 is abruptly lifted by a wave crest, the spring 2 is extended. A magnet 3 is moved relatively downward with respect to the floating body 1, and the magnetic lines of force of the magnet interlinked with a power generating coil 6 generate the electromotive force. When the floating body 1 next sinks in a wave trough, the spring 2 is shrunk. The electromotive force is generated on the power generating coil 6 by the moving stroke of the magnet 3. Electric power is effectively obtained with a small number of components.

Title: Epitaxial crystal growth method
Inventor: HAYAFUJI AKIO
IPC: H01L21/302
Filed: 1988-03-02
Abstract: PURPOSE:To obtain gallium arsenide, dislocation of which is reduced, by preventing propagation to the outermost surface of gallium arsenide of dislocation when gallium arsenide having high quality is formed by epitaxial growth onto a silicon substrate. CONSTITUTION:A low-temperature gallium arsenide layer 6 is grown onto an silicon substrate 1, and a gallium arsenide layer 2 is grown onto the layer 6 as a buffer layer. A lattice mismatching layer having a lattice constant different from gallium arsenide such as an indium arsenide layer 3 is grown onto the layer 2. Only the indium arsenide layer 3 is removed selectively through etching. Lastly, a gallium arsenide layer 4 is grown onto the layer 2. Consequently, dislocation 5 generated on the interface of the silicon substrate 1 and the buffer layer and gradually propagated in the growth direction is bent and made to escape in the direction vertical to the growth direction on the interface of the gallium arsenide layer 2 and the indium arsenide layer 3. Even when the indium arsenide layer 3 is gotten rid of through etching as shown in the Fig. b, the state of the dislocation 5 is not changed. When the gallium arsenide layer 4 is grown onto the layer 2, the dislocation 5 is not propagated to an upper section because the dislocation 5 is bent by the uppermost surface of the gallium arsenide layer 2. Accordingly, the gallium arsenide layer, dislocation of which is reduced and which has high quality, can be acquired.

Title: Transmission retrial control system
Inventor: CHIBA HIDEAKI
IPC: H04L69/14
Filed: 1988-03-02
Abstract: PURPOSE:To relieve the load on a control program and to improve the reliability by returning the transmission start state set in a 2nd control area to a 1st control area if an error takes place in the transmission state to apply retrial control to the same transmission data. CONSTITUTION:In the case of semi-duplex communication, the transmission start state set in the 1st control area 11 is set to the 2nd control area 12 prior to the start of transmission. Then the state set in the 2nd control area 12 is unchanged but stored till the transmission is finished. When an error takes place in a test transmission and a faulty reply text from the communication opposite party is detected by a fault detection circuit 4, the transmission start state set in the 2nd control area 12 is transited to the 1st control area 11 to restore the state of the 1st control area into the transmission start state relating to the transmission data, thereby applying retrial control of the transmission without intervention to the program. Thus, the control program load is relieved and the reliability is improved.

Filed: 1993-03-10
Abstract: PURPOSE:To enhance characteristics at high and low temperatures, and thereby obtain electrolytes high in performance by impregnating the electrolytes with mixed solvent mainly composed of ethylene carbonate, and of organic solvent having a specified melting point and a specified boiling point. CONSTITUTION:Electrolytes are impregnated with mixed solvent mainly composed of ethylene carbonate, and of organic solvent which remains in a liquid state at -20 deg.C, and has a boiling point greater than 160 deg.C at atmospheric pressure. In the case of organic solvent, if a temperature for solidification is high, discharge characteristics are degraded at low temperatures, and if a boiling point is low at atmospheric pressure, safety is lowered when the solvent is erroneously used, and there are hydrocarbon compound such as decane, butyl benzene and the like, ester group such as diethyl phthalate and the like, either group, ketone group and the like. As electrolytes, lithium salt is preferable. The adoption of the aforesaid electrolytes in a non-aqueous battery which can be charged/discharged, and is composed of a positive electrode 1, a negative electrode 2 and a separator 3 permits characteristics at high and low temperatures to be enhanced.
