Title: Hollow cathode
Inventor: YOSHIKAWA KANZOU
IPC: H01J1/13
Filed: 1988-12-16
Abstract: PURPOSE:To make a cathode pipe resistant to corrosion even if an oxygen gas is generated from an impregnation cathode by forming a sheath layer having the characteristics of heat resistance, thermal conduction and oxidation resistance on the external surface of the impregnation cathode. CONSTITUTION:The external surface of an impregnation electrode 4 working not as an electron emission surface but as an oxygen gas emission surface is covered with a layer having the characteristics of heat resistance, thermal conduction and oxygen resistance, for example, a high temperature wax material 7 such as Mo-Ru. The emission of an oxygen gas from the external surface of the cathode 4 adjacent to a cathode pipe is thereby prevented. According to the aforesaid construction, it is possible to alleviate the corrosion of the cathode pipe and obtain a hollow cathode of long lifetime.

Title: Inrush current suppression circuit
Inventor: MIHARA KENJIROU
IPC: H02H9/02
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To obtain a circuit for suppressing the peak value of inrush current to a heater by connecting a parallel circuit of a positive characteristic thermistor and a negative characteristic thermistor having resistance higher than the normal temperature resistance of positive characteristic thermistor in series with a circuit having the heater. SOLUTION: A parallel circuit 13 of positive and negative characteristic thermistors 11, 12 having normal temperature resistance R1, R2 is connected in series with a halogen heater 15 thus constituting a circuit having a heater. The normal temperature resistance R1, R2 of two thermistors are selected to satisfy a relationship R1>R2. Since the halogen heater 15 has low resistance, a voltage load is applied to the parallel circuit 13 when power is turned on. At first, a current flows into the positive characteristic thermistor 11 having low normal temperature resistance and then a current flows gradually into the negative characteristic thermistor 12 as the resistance increases through self-heating. According to the circuit, inrush current can be suppressed over a wide range after turn on power before reaching a rated current.

Title: Recording material
Inventor: MATSUOKA KATSUMI
IPC: B41M5/165
Filed: 1987-12-15
Abstract: PURPOSE:To improve light resistance of a microcapsule layer by using a p- substd. aminophenylindolylphthalide derivative or the like as a color former and using microcapsules containing a phthalic acid ester of the like having a boiling point not lower than a specified temperature therein as a solvent. CONSTITUTION:In a recording material, at least one of a p-substd. aminophenylindolylphthalide derivative, a p-substd. aminopheylindolylazaphthalide derivative and a p-substd. aminophenylindolyldiazaphthalide derivative is used as a color former, and microcapsules containing at least one selected from a phthalic acid ester, a fatty acid ester, a dihydric alcohol ester and an oxyacid ester having a boiling point of at least 280 deg.C at a pressure of 760mmHg in an amount of 1-40wt.% based on the core substance are used as a solvent. The phthalic acid ester or the like remains on a color developed surface after printing, thereby uniformizing a developed color image. Therefore, it is necessary for the boiling point at 760mmHg of the phthalic acid or the like be not lower than 280 deg.C. If the amount of the solvent is less than 1wt.% based on the core substance, the effect of the solvent is poor, whereas an amount of more than 40wt.% worsens the light resistance of the coloring matter.

Title: Production of match having flying spark
Inventor: TAKAHASHI TAMAKI
IPC: C06F3/04
Filed: 1989-12-06
Abstract: PURPOSE:To obtain a match scattering beautiful spark on all sides during ignition by adding a process of attaching paraffin and iron powder as well to the outer periphery of a match stem in the production. CONSTITUTION:Immediately after the outer periphery of match stems is coated with heated, molten liquid paraffin, iron powder is attached to the outer periphery before the paraffin is cooled and solidified, then the paraffin is solidified and the iron powder is caught and fixed. A method wherein the iron powder is premixed with the liquid paraffin and attached to match stems may be applied. Then a head chemical for ignition is stuck to the stem to produce a match. Consequently, when the head chemical of the match is lighted, paraffin is melted with transfer of spark to a match stem, iron powder is released, oxidized and burnt in flame with combustion of the match stem and the iron powder becomes a fireworks-like beautiful small spark and scatters on all sides.

Title: Manufacture of lightweight composite formed product
Inventor: YAMAMOTO SHIRO
IPC: B29C70/06
Filed: 1989-12-08
Abstract: PURPOSE:To obtain composite formed product, which has favorable surface and is useful for lightweight structural material such as honeycomb material, by a method wherein non-thermally expandable lightweight elastic body particles are used in combination with thermally expandable foamable resin particles. CONSTITUTION:Liquid curable resin and/or its stock are introduced in a forming mold. The introduction of the resin and its stock is stopped after their overflowing is confirmed. When foamable resin particles are expanded by being heated under the condition that a nozzle above the mold is opened, a separating layer is pushed against the inner surface of a mold and, at the same time, liquid resin and/or its stock are permeated in the separating layer and some part of it reaches the outside front layer part of formed product. And the liquid curable resin and/or its stock are hardened while being overflown through the nozzle. Elastic particles are once contracted by the pressure developed through the expansion of the foamable resin. When the contraction of the formed particles starts after the peak of expansion, the elastic particles expand so as to compensate the contraction of the foamed particles, resulting in acting so as to prevent resin starved part from developing in the formed product. After the hardening of the resin, the formed product is cooled and removed from the mold.

Title: Image forming device
Inventor: YOSHINO NAOTO
IPC: G03G15/00
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To form an excellent toner image, without damaging a sheet of paper and an unfixed image, even if the difference in speed is made between a paper carrying means and a fixing device by setting plural paper carrying devices, so that the carrying speed of the paper carrying device on the upstream side is faster and the suction force of the paper carrying device on the downstream side is greater. SOLUTION: The suction force of the first paper carrying device 4 is made smaller than that of the second paper carrying device 5. Then, the suction force of the first paper carrying device 4 is set to such a degree that a transfer paper 3 slips on the first paper carrying device 4, not to be buckled. Thus, the carrying speed of the first paper carrying device 4 can be freely set regardless of the second paper carrying device on the downstream side. Thus, the carrying speed of the first paper carrying device 4 can be set to make the transfer paper 3 next fed from a transfer device acceptable at all times, so that even if the speed of the fixing device 6 is reduced, a printing cycle can be advanced without decrease in productivity.

Abstract: PURPOSE:To supply stabilized current to a load coil by providing a low-pass filter and a switching circuit which allows only an output signal from a reference signal generation circuit to be supplied to a power supply via the low-pass filter. CONSTITUTION:A low-pass filter 10 is provided along with a switching circuit S2 which functions in such a manner that it does not route a signal via the low-pass filter 10 if the signal is one, obtained by adding together an output signal from a reference signal generation circuit 1 and an output signal from a wobbling signal generation circuit 2, that is to be supplied to a power supply 4 or it routes a signal via the low-pass filter 10 if the signal is an output signal from the reference signal generation circuit 1 alone that is to be supplied to the power supply 4. This arrangement can supply stabilized DC current to a load coil even when the power supply 4 uses circuit elements, such as operational amplifiers, that have wide-band characteristics, since the noise component of the output signal from the reference signal generation circuit 1 is removed by the low-pass filter 10.
