Title: Method and equipment for treatment of foamed polystyrene as waste
Inventor: EGI ITSUO
IPC: B29K75/00
Filed: 1992-02-17
Abstract: PURPOSE:To make foamed polystyrene a material optimum for reclamation by a method wherein the foamed polystyrene is subjected to a volume reduction treatment by raising the temperature thereof by heating at a temperature not exceeding a melting temperature in a vacuum atmosphere and thereby the reaction with other gases is eliminated during the volume reduction treatment. CONSTITUTION:A supply chamber 1 provided with a valve 4 for interception from the atmosphere and retention of airtightness is provided below a charging hopper 10 in which foamed polystyrene to be treated as a waste is charged, and a treatment chamber 2 is disposed below it. A supply valve 5 is provided between the supply chamber 1 and the treatment chamber 2, while a discharge valve 6 is provided between the treatment chamber and a discharge chamber 3 below it. Pipings 13, 14 and 15 for vacuum exhaust are provided for the chambers 1, 2 and 3 respectively and thereby each of the chambers 1, 2 and 3 is put in a vacuum atmosphere discretely or jointly by a vacuum exhaust device 12. A heating device 8 is disposed in the treatment chamber 2 and the waste in the treatment chamber 2 is subjected to a volume reduction treatment by heating. At the time of this volume reduction, gases such as oxygen become very thin in the vacuum atmosphere and components of materials are not burnt, but retained even when the waste is heated to a melting temperature, and can be used as materials for reclamation.

Title: Printing head cooling control system of printer
Inventor: KAWAMURA TOSHIO
IPC: B41J29/377
Filed: 1986-04-07
Abstract: PURPOSE:To shorter a temp. lowering time and to also dispense with a space for arranging a fan, by performing printing-free spacing at the high temp. time of a printing head. CONSTITUTION:The high temp. of a printing head is checked in a line unit during the interruption processing of a program timer at every 10ms immediately before printing. At first, because the checking is performed in the line unit in a step 11, it is checked whether spacing operation is performed. Unless spacing operation is performed, the temp. of a printing head is checked in a step 12 and, if high, printing-free spacing operation only of one line is started as shown in a step 14. Until the temp. of the printing head is lowered, this operation is repeated and, if the temp. of the printing head is lowered, the usual printing operation of the step 13 is started.

In this method lightweight metallic hangers 2 each of <=200g are used to adjust the depth of recesses 11 formed at the plate 1 portions contacting to hangers 2 to 0.05-0.45mm.. It is confirmed experimentally that a strength lowering of tempered glass in the vicinities of the recesses depend on the depth of the recesses, not the diameter. Thus, a tempered glass plate having practical strength is obtd. from such a lightweight glass plate.

Title: Method for producing cdte semiconductor single crystal
Inventor: TANAKA AKIKAZU
IPC: C30B11/00
Filed: 1995-03-13
Abstract: PURPOSE: To obtain a method for simply producing a CdTe semiconductor fin single crystal of good crystallinity by the temperature-gradient method. CONSTITUTION: In the production of a CdTe semiconductor single crystal by the temperature gradient method, the temperature at which the melt of CdTe semiconductor in the supercooled state starts solidifying, is detected, as the outer-wall temperature of the vessel, by using a thermocouple (temperature sensor) 6 set to the outside bottom of the vessel 1 on the way of gradual cooling process. After the detection, the oven 4 is heated to raise up the temperature of the melt in the vessel near the melting point Tm of the semiconductor (Tm' where Tm>Tm'), as the temperature of the oven 4 is kept constant to adjust the melt temperature to Tm' and then the oven 4 is gradually cooled down to precipitate CdTe semiconductor crystal on the CdTe crystal formed on the solidification start as a seed crystal.  Since the melt is heated up near the melting point of the semiconductor immediately after the solidification started, the conversion of the precipitating crystals to polycrystals can be avoided. Further, the crystal formed at the time of starting solidification can be used as a seed and the production cost is reduced.

Title: Water-seal device for hydraulic machine
Inventor: SUZUKI MUTSUO
IPC: F16J15/447
Filed: 1978-07-05
Abstract: PURPOSE: To remarkably improve a reliability of the water-seal part itself, as well as to simplify a work of inspecting the water-seal part and to widely shorten a length of labor time required for the work of inspection and maintenance, with a process of inspection only for the water-seal part made enough for requirement, by means of constructing a fine clearance to a minimum for the place to be measured.  
     CONSTITUTION: A clearance G 5  of the second stage water-seal part is set to a width slightly wider than a clearance G 4  of the first stage water-seal part. The amount of leak from such clearance as in the above, if assumed L for a length of the water-seal part, is proportional to the cube of the clearance and inversely proportional to the length L. The clearance of the second stage water-seal part is to be generally set to about G 5 =(G 4  + 0.1mm). In case of increasing a number of stages of the water- seal part likely as third, fourth, and so on, those of the clearance of the water-seal part will be made equal to the clearance G 5  of the second stage water-seal part. In such way, a construction of the clearance G 4  of the first stage water-seal part, of the place to be measured, to minimum amount makes the work of inspection and surveillance only required for this part, capable of eliminating a necessity of inspecting other water-seal part.

Title: Formant sound synthesizing device
Inventor: NISHIMOTO TETSUO
IPC: G10H5/00
Filed: 1989-04-03
Abstract: PURPOSE:To synthesize a formant sound close to a natural sound by multiplying a 1st waveform which has an independent repetitive period by a 2nd waveform which has a longer period than the 1st waveform and differs in shape between the front half period and latter half period. CONSTITUTION:A phase accumulator 32 accumulates a band width value (ka) for the front half period and band width value (kb) for the latter half period which are supplied through a selector 31 and outputs the result as the readout address signal of a sine square wave memory 33, and a sine square wave amplitude value is read-out of the memory 33 successively. In the former half period, the value is read-out at a period corresponding to the band width value (ka) for the former half period and in the latter half period, the value is processed asymmetrically and read-out at a period corresponding to the band width value (kb) for the latter half period. An adder 4 adds the sine wave amplitude value outputted from a carrier waveform generating circuit 2 and the sine 2n-power amplitude value outputted by a bit shifter 35. Thus, a window waveform which is asymmetrical between the former half period and latter half period is used, so the formant sound having a spectrum which has a sharp peak and a wide bottom and a close to a natural sound can be synthesized.

When the head chip 12 is brought into contact with the magnetic tape, it is brought into contact with the magnetic tape smoothly because the contacting face has a large radius of curvature in the entrance side 12b, and the air film between the magnetic tape and the drum is formed easily. Consequently, a stable picture quality is attained.

IPC: C07C239/00
Filed: 1980-06-17
Abstract: PURPOSE: The reaction of a hypohalite with aldehyde and hydroxylamine salt gives the titled compound that is used to produce an insecticide in one-stage by no use of a large amount of base.  
     CONSTITUTION: A hypohalite salt is made to act on an aldehyde of formula I (R is lower alkyl) such as acetaldehyde and a hydroxylamine salt such as hydroxylamine hydrochloride to give the titled compound of formula II (X is halogen). The example of the hypohalite is sodium hypochlorite and the amount is usually 0.5W2.0mol, preferably 0.8W1.2mol/mol of the aldehyde. When the amount of the hypochlorite  used is too small, the reaction does not proceed sufficiently, whereas an excessive  amount undesirably causes the halogenation and oxidation of the objective product.  Since the hypohalite plays roles of both neutralizer and halogenating agent in the  conventional process, a large amount of base becomes unnecessary.
