Title: Extrusion molding device for multi-layer parison
Inventor: FUKUHARA KEIJI
IPC: B29C48/09
Filed: 1989-09-21
Abstract: PURPOSE:To form a multi-layer parison having a resin layer without unevenness all over, even if resin of comparatively high moisture absorbing properties is used, by setting variable extrusion pressure of an extruder based on the water absorbing rate of the resin sensed by a sensing means. CONSTITUTION:An extrusion molding device 10 is provided with a water absorbing rate sensor 110 for measuring the water absorbing rate of nylon as an auxiliary material in a material feeding system and an auxiliary material/ bonding agent control circuit 101 constituted for setting variably the target extrusion pressure of a second extruder 12 based on the water absorbing rate of nylon sensed by the water absorbing sensor 110. When the water absorbing rate of nylon is high and the melting viscosity of molten nylon in an accumulator 20 is low, the target extrusion pressure of the second extruder 12 is set low to control the action of a second electromagnetic proportional type pressure servo valve 107 and control the nylon not to be extruded in excess. On the other hand, when the water absorbing rate of nylon is low, the target extrusion pressure of the second extruder 12 is set high to control the action of the second electromagnetic proportional type pressure servo valve 107 to prevent the shortage of extrusion quantity of nylon.

Title: Lighting device for lamp
Inventor: SEKINE SHINJI
IPC: G03G15/04
Filed: 1990-09-18
Abstract: PURPOSE:To enhance the accuracy of detection when detecting a voltage applied to a lamp by providing a half-wave rectifier circuit which rectifies only the forward component of pulse voltage applied to the lamp and detected by a transformer so as to eliminate flyback. CONSTITUTION:A unipolar pulse voltage applied to a lamp 16 is detected by a transformer 17 and bipolar pulse is output to the output end of the transformer 17. The forward component of the bipolar pulse is the voltage applied to the lamp 16 and its flyback is electromagnetic energy stored in the inductance component of the transformer 17 and is therefore error to the voltage applied to the lamp. Then only the forward component being output from the transformer 17 is half-wave rectified by a half-wave rectifier circuit so as to eliminate the flyback that causes the error. Detection accuracy for the voltage applied to the lamp and detected by the pulse transformer 17 is thus enhanced.

Title: Dioxin reduction method and dioxin treating agent
Inventor: TAMAGAWA KOTAI
IPC: A62D101/08
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To easily suppress the generation of dioxins and to easily remove or reduce dioxins present in soil and incineration ash, by spraying pyroligneous acid, which is a dioxin treating agent, to soil, and incineration ash or waste before incineration respectively. SOLUTION: Pyroligneous acid is sprayed to and mixed with soil and incineration ash containing dioxins, thereby reducing dioxins. And the pyroligneous acid is sprayed to and mixed with waste before incineration, thereby suppressing the generation of dioxins. In this case, the pyroligneous acid is obtained by collecting gaseous component generated when wood is thermally decomposed to be carbonized, and cooling the gaseous component. It is especially preferable that crude pyroligneous acid containing a large quantity of phenols having an excellent effect to reduce dioxins is used. In addition, the spraying amount of the pyroligneous acid is appropriately determined, for example, when it is sprayed to the incineration ash, the weight of spraying pyroligneous acid is 0.1 to 5 times that of the incineration ash.

Abstract: PURPOSE:To reduce crosstalk noise by using a different color signal on a 1st line of both 1st and 2nd fields when (n) is an odd number and using a same color signal on the 1st line of both the 1st and 2nd fields when (n) is an even number, where nH is a recording start position of the 1st and 2nd fields on a tape. CONSTITUTION:The line sequential switching is controlled so that a color signal of a 1st line of a 1st field is started from a signal CA and a color signal of a 1st line of a 2nd field is started from a signal CB. Thus, a same color signal is arranged between adjacent tracks in a same frame. That is, the color signal adjacent between all tracks is of a same kind and the adverse effect of crosstalk is reduced. That is, a line valid for recording is deviated by 1H in the 2nd field and line numbers of the 1st line in the 1st and 2nd fields are selected to be an odd number and an even number. Thus, a same kind of color signal adjacent between all tracks is selected.

Title: Bar-code recognizing system
Inventor: SATO JUN
IPC: G06K9/38
Filed: 1985-11-05
Abstract: PURPOSE:To read exactly a bar-code by preparing plural thresholds, and binarizing a binarization image by an appropriate density threshold value. CONSTITUTION:When the read part of an OCR device which is reading successively a character being on a slip form comes to the vicinity of a bar-code area, a signal B for informing the bar-code area is applied to a read control circuit 4. As a result, from the read control circuit, a threshold determined in advance, for instance, Th1 is outputted. A binarization circuit 2 executes a conversion to two values of '1' and '0', based on this threshold Th1 and stores its value in an image memory 3. Next, a comparator 56 in a recognizing part 5 compares said value with a numerical value held by a reference number holding part 55, and in case when it does not coincide, its data is returned to the read control part 4. By receiving it, the read control circuit 4 executes a transfer to a binarization circuit 2 so that binarization can be executed by other threshold Th2 inputted in advance.
