Title: High frequency gain variable amplifier
Inventor: KABETANI YUKIO
IPC: H03F3/45
Filed: 1987-08-10
Abstract: PURPOSE:To decrease the deterioration in the gain attenuation at a high frequency by providing a differential transistor(TR) amplifier circuit, a control circuit varying the gain of the said amplifier circuit and a passive element circuit with a high frequency low impedance connected to one of output terminals of the differential TR amplifier circuit. CONSTITUTION:An input signal is supplied from an input terminal 8, amplified by a common emitter TR 1 and a common base TR 2 and the result is outputted to an output terminal 9. In this case, the gain control terminal 10 is set to a potential where the base potential oaf the TR 2 is higher than the base potential of the TR 3 to turn off the TR 3 completely thereby maximizing the gain of the amplifier. Then the potential of the gain control terminal 10 is lowered to turn off the TR 2 completely thereby minimizing the gain of the amplifier. The collector of the TR 3 in the amplifier circuit has a low impedance at a high frequency due to the series resonance of the passive component circuit 5 comprising the series resonance circuit. Thus, the deterioration in the gain attenuation at a high frequency is reduced.

Title: Developer carrier
Inventor: SAIKI KAZUNORI
IPC: G03G15/08
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To prevent decrease in the image density or production of white stripes or blots by forming a conductive resin coating layer having particles treated with a release agent on the surface of a developer carrier. SOLUTION: The coating layer 1 consists of particles 2 treated with a release agent, a conductive material 3, a binder resin 4 and a solid lubricant 5. At least the particles 2 treated with a release agent and the conductive material 3, and if necessary, the solid lubricant 5 are dispersed and bonded in the binder resin 4 which is applied on a cylindrical base body 6. In the developer carrier having the coating layer 1 above, even when the coating layer 1 is worn by long-term use, the particles 2 treated with the release agent are exposed in the coating layer 1 so that the lubricating property and release property of the coating layer 1 can be maintained. Therefore, melt sticking of a toner on the developer carrying body can be prevented. Since the coating layer 1 is conductive, excess electrification of the toner can be prevented.  Moreover, since the toner can be electrified in a good state by the treated particles 2, good image density can be obtd. especially even at a high temp. and in high humidity environment.

Title: Method and device for repairing pipe branch part
Inventor: IMOTO TAKAYOSHI
IPC: F16L57/00
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To repair the branch part of a pipe through the length from a main pipe to a branch pipe securely by expanding the branch part of a bag against the suppressing force of an expansion suppressing member so as to fit the tubular branch part of a repair member closely to the inter-branch inner surface of the pipe and then increasing the rigidity of the repair member. SOLUTION: When the base part 7 of a bag 9 is inflated sufficiently and the tubular base part 5 of a repair member 4 is fitted closely to the inner surface of a main pipe 1 by the expansion of it, a fluid pressure in the bag 9 rises and internal pressure is also applied to a branch part 8. Therefore the tubular branch part 6 of the repair member 4 is also expanded against the suppression by an expansion prevention member 11, and fitted closely to the inner surface of a branch pipe 2. Under this condition, when heating fluid such as pressurizing steam or hot air is fed into the bag 9 so as to heat the repair member 4 and hardening resin liquid is cured, an FRP internal lining is formed at the branch part of a pipe and its surroundings, and the branch part is repaired.  Thus, because the tubular branch part 6 is expanded and fitted closely to the branch pipe 2, the branch part of the pipe can be repaired securely through the length from the main pipe 1 to the branch pipe 2.

Title: Fuel injection pump driving device

IPC: F02D1/08
Filed: 1984-09-28
Abstract: PURPOSE:To make it possible to smoothly operates an accelerator, by utilizing a step motor for electrically controlling a load lever which drives a fuel injection pump in accordance with the displacement of the accelerator. CONSTITUTION:When an accelerator 20 is depressed, the detection voltage of an accelerator displacement detector 22 varies so that the balance between the detection voltage and the output voltage of a D/A converter 36 in a load lever position detector 30 within a control circuit 24 becomes lost, and therefore, a comparator 32 delivers a positive drive signal Sd to a drive circuit 28 to rotate a step motor 18 for driving a load lever 14, in the positive direction. At this time an up-down counter 34 serves as an up counter so that the output voltage of the D/A converter 36 increases. Further, when the output voltage of the D/A converter 36 comes to be equal to the detection voltage of the accelerator displacement detector 22, the drive signal from the comparator 32 disappears so that the step motor 18 comes to a stop.
