Title: Voice packet processing device
Inventor: ONO MASAFUMI
IPC: H04Q11/04
Filed: 1988-06-01
Abstract: PURPOSE:To use a prediction value used at encoding as it is for decoding by utilizing an interval between voice packets on a transmission line and informing the internal state at the encoder side for the decoding side. CONSTITUTION:An internal state readout control section 414 monitors a buffer 406 through a control line 2000. When the storage of an ADPCM signal filling a packet data length to the buffer 406 is finished, a command is given to an internal state readout section 415 in a way that contents 1002, 1003 of registers 401, 402, a prediction coefficient 1008 used for calculating by a prediction device 403 and a quantized factor 1009 used for a recording adaptive quantizer 405 are read out. Thus, the internal state 1010 is read to an internal state packet combination section 604 from the readout section 415 to generate the internal state packet 215 of the same length as that of the voice packet 211 and it is sent to a transmission line. Since the voice packet and the internal state packet are handled as the packet of the same length, the processing is proper to the high speed packet exchange.

Abstract: PURPOSE: To develop a plasma thermal spraying gun excellent in heating effect at the low frequency by using the Ar-He mixture gas as the plasma gas in a radio frequency plasma thermal spraying device.  
     CONSTITUTION: After a vacuum tank 12 in which a base material 63 to be treated is arranged toward a plasma gun 30 by a fuming mechanism 66 is evacuated to the pressure of ≤500 micron Hg by a vacuum pump 50, the He-Ar mixture plasma gas consisting of, by volume, 20-90% He and 10-80% Ar is fed with the pressure of 150-350 Torr.

Title: Automatic power multiplexing device
Inventor: NISHIDA KENJI
IPC: H02J9/06
Filed: 1977-11-09
Abstract: PURPOSE: To prevent power supply lines from shorting by automatically controlling the operation of load connecting relays depending upon the utility of the power supply lines.  
     CONSTITUTION: When the power is applied to the power supply line 1, an active line detection relay 13 is turned on, and a load connecting relay 6 is turned off. Then, a load connecting relay 5 is turned on to thus connect the load 4 to the power supply line 1. When the power is applied to the power supply line 2, if the power supply line 1 is deenergized, the relay 6 is turned on to cause the load 4 to be connected to the line 2. Since the load connecting relay 5 is interlocked at its normally open contacts 7, 8 with normally closed contact 12, when the load 4 is connected with the line 1, the relay 6 cannot be turned on so as not to short therebetween. The normally open contacts 9, 10 of the relay 6 are interlocked with the normally closed contact 11 to thus prevent them from shorting when the load 4 is connected to the line 2.

IPC: G11B7/00
Filed: 1987-05-29
Abstract: PURPOSE:To reduce crosstalk without complicating the constitution by forming an incident aperture nearly to a rhombic shape, and making a diagonal line orthogonal to a track of an information recording medium. CONSTITUTION:The aperture 7 arranged to the side of the light source 1 of an objective lens 4 is formed to be rhombic, the aperture 7 is formed nearly to be a square and a diagonal line is arranged so as to be orthogonal to a track direction A of an optical disk 2.

Abstract: PURPOSE:To eliminate interruption of printing process due to runout of paper and thereby shorten time required for printing work by starting at a specified time interval a status holding device which holds information on a paper setting status and a paper feed status, a function selection device which selects a function to start or end paper feed and a function instruction device which instructs the device. CONSTITUTION:If there is any paper feed device which remains unchecked among other paper feed devices following the initialization of a storage area, procedures to be taken are decided based on information from a status control table. If paper supply runs out in the paper feed mode, a function command device 15 is instructed to command any appropriate paper feed device to stop. If any one of the paper feed devices is operative after it had paper running out of stock previously but is actually not feeding paper with paper set in position, the function command device 15 is instructed to command any appropriate paper feed device to start. If one paper feed device is checked, all the paper feed devices are checked, and any required procedures are decided based on the check results after completion of the checking.

Title: Method for working outer diameter shape of tubular member
Inventor: KANAMARU NAONOBU
IPC: B21J5/06
Filed: 1982-08-02
Abstract: PURPOSE:To form a groove or tooth form excellent in dimensional accuracy, by forming a groove or tooth form by plastic work giving tensile force to a tubular member when forming a groove or tooth form on the outer peripheral face of a tubular member. CONSTITUTION:When forming outer diameter helical involute tooth form 23 on the outer peripheral face of a tubular material 4, a bottom part 14 and stepped outer diameter 21 are formed on an end of the tubular material 4, and held by inner face of a die 1 having a die 5 for forming a gear on inner face. At the same time, a plunger punch 8 is fitted to inner diameter from the open end of the material 4. Under this condition, the material 4 is inserted by pressure. Since the plunger punch 8 presses the material while rotating, helical involute tooth form 23 is plastic worked on the outer peripheral face of the material 4. As tensile stress is given to the material 4 during plastic work, deformation resistance to plastic work becomes small, and tooth form can be plastic worked by small force.
