Inventor: NAKANO KOUSAKU
IPC: C08L101/00
Filed: 1981-10-05
Abstract: PURPOSE:To provide a flame-retarding compsn. having a sufficient flame retardance and a high tensile strength, prepared by adding a flame retarder to a high- density polyethylene with specified melt index and molecular weight. CONSTITUTION:A flame retarder is added to a high-density polyethylene having a melt index of 0.1 or lower and a number-average molecular weight of 200,000-800,000. If the melt index exceeds 0.1 and the number-average molecular weight is less than 200,000, the resin loses elongation and is no longer usable when a filler is added in about 80pts.wt. per 100pts.wt. resin. If the melt index and number-average molecular weight exceed 0.1 and 800,000, respectively, the resin becomes difficult to process and form and produces moldings with poor appearance. The flame retarders are antimony trioxide, halogen compds., zinc borate, magnessium carbonate, etc.

Title: Sample-and-hold circuit
Inventor: KIMURA HIROYUKI
IPC: H04B1/04
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To provide infinite hold time not depending on a circuit constant and to prevent a held voltage from being dropped by discharging by detecting the timing of burst-on of a transmission carrier wave, storing and holding the detected output as a digital value. SOLUTION: A detector output 14 passed through an analog switch 5 is inputted to a monitor circuit 27, converted into a digital value by an A/D converter 2, stored at the rise time point of a 3rd switch signal 22 and outputted to a D/A converter 4 as a hold circuit level Dab. Concerning this output, the 1st analog switch 5 is nonconducted and an analog switch 6 is conducted at the next time point so that a hold signal Vab can be outputted. When an output level Vcd is inputted as the detector output 14 during the next burst-on period, the similar operation is repeated and the output level Vcd is outputted to the circuit 27. Therefore, since the output levels Vab and Vcd are held at respective digital output levels Dab and Dcd, the output can be held like storage due to a capacitor without depending on the circuit constant.

Filed: 1988-06-24
Abstract: PURPOSE:To save an energy for a freezing cycle by a method wherein if a cooling load is high, a target value of an over-heating operation is corrected to have a low value, a degree of expansion of coolant for evaporating means is controlled by an expansion valve means to decrease a degree of over-heating of the evaporated coolant. CONSTITUTION:When a cooling load of a freezing cycle to be detected by a detecting means 5 is high, a target value of a degree of over-heating of evaporating coolant from an evaporating means 1 to a compressing means 2 is corrected by a correcting means 6 to get a low value. An expansion valve means 4 controls a degree of expansion from a condensing means 3 to an evaporating means 1 so as to decrease a degree of over-heating operation and a cooling capability of the freezing cycle, i.e. a cooling capability in the evaporating means 1 is sufficiently assured in correspondence with a high cooling load. In turn, when a cooling load is not high, the correcting means 6 corrects it in such a way as the target value of the degree of over-heating operation is high and the cooling capability is sufficiently assured and at the same time it is controlled to the degree of over-heating with the highest efficiency of operation, resulting in that an energy saving of the freezing cycle can be increased more.

Title: Resin impregnation testing for ferrous sintered alloy
Inventor: SHIRAI KAZUO
IPC: B22F3/26
Filed: 1981-10-06
Abstract: PURPOSE:To obtain a simple inspection method that provides clear judgement by submerging a ferrous sintered alloy with resin impregnation in aqua regia of chloric and nitric acids of a suitable concentration, and after dissolving only the ferrous component, washing the alloy with water and judging the quality of the alloy by apperance inspection. CONSTITUTION:Many samples are made, and they are divided in a, b, and c parts, and the central part b is used as the sample. This sample is immersed in chloric acid and nitric acid diluted by water in the ratio: wate: acids=1:1, or in aqua regia at the temperature and time that are beforehand set up. In the solution only the ferrous component is dissolved and only the resin is left. As a result, if the impregnation of resin is good, the ferrous component of a sample dissolves completely in the acid solution, and when only the resin is left, almost the original shape of the sample is retained. If a sample with not satisfactory impregnation resin, its original shape can not be retained and it is largely deformed. If the resin impregnation is not complete, and only the surface layer of a sample has resin impregnation, the central ferrous part is dissolved and disappears. By this method resin impregnation quality can be clearly and easily juded.

Filed: 1987-06-25
Abstract: PURPOSE: To enable amplifying operation which is stable up to a high frequency without causing any oscillation by connecting a capacitor for compensating phase delay in parallel to the feed back loop of an amplifier and moving an electrode which causes oscillation to the high prequency side.  
     CONSTITUTION: The feedback loop 14 is formed which applies an input signal Vi to be amplified to the uninverted input (+) side of the operational amplifier 2 from a signal source 4 and also feeds an output signal Vo back to its inverted input (-) side. Further, the capacitor 44 for compensating the phase delay due to parasitic capacity generated on the inverted input (-) side is connected in parallel to the feedback loop 14. The output signal Vo of the operational amplifier 2 is therefore led out through an output terminal 8 and fed negatively back to the inverted input (-) side through the feedback loop 14. The electrode moves because of the capacity Ci of this capacitor 44 to compensate the phase delay due to the parasitic capacity Co, thereby enabling the amplifying operation which is stable up to the high frequency range.

IPC: F02M35/10
Filed: 1980-11-13
Abstract: PURPOSE: To promote the charging efficiency in the whole area of driving for increasing output in a main suction passage equipped with a one-way valve such as a reed valve or the like by providing a control passage connected to a  supply chamber near the initial opening part of the above-said valve.   
     CONSTITUTION: In the medium and high speed area of revolution of an engine, a reed valve 4 is opened by suction negative pressure, and the air-fuel mixture produced in a carburetter 1 is supplied into a combustion chamber. At this stage, the air-fuel mixture is supplied to a main suction passage 12b on the downstream side of a reed valve 4 by the suction inertia of the air-fuel mixture even after the finishing of a suction stroke, and the reed valve 4 is closed at the time point when pressures are balanced between both passages 12a and 12b. Consequently, the air-fuel mixture inside the passage 12b is enclosed in a state of comparatively high pressure, and works to smooth the supply of the air- fuel mixture in the next stroke. At this stage, when the reed valve 4 is opened, negative pressure is introduced into a supply chamber 13 via a control passage 14, and sucks the air-fuel mixture forcedly when the valve is closed. This construction permits to promote the charging efficiency of the air-fuel mixture.
