Title: Ink-jet recording apparatus
Inventor: NIIMI ETSUO
IPC: B41J2/175
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To realize an ink pressure control corresponding to an environmental temperature change by controlling a temperature of an ink pressure unit. SOLUTION: A pressure adjustment spring 212 at an ink pressure adjustment unit 2 which adjusts an ink output pressure supplied to nozzles to compete with a pressing force of the pressure adjustment spring 212 is supported by a case which expands and shrinks in accordance with a temperature. A temperature control is applied to the ink pressure adjustment unit 2. The case expands in accordance with a temperature increase, thereby decreasing the pressing force of the pressure adjustment spring to lower the ink output pressure. A change in ink pressure supplied to the nozzles is thus restricted. The temperature control is carried out while comparing a temperature change with an ambient temperature when a reference ink pressure is set and an environment temperature.

Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To provide a power source obtaining a low peak output current and obtaining more current pulses between each cycle of an AC input voltage. SOLUTION: Voltage waveform VREC, which is not filtered and is full-wave- rectified, is supplied to a power source 10 with a switching device Q1 operating between a perfectly conductive state and a non-conductive state and a reference voltage circuit 13. When a rectified voltage waveform is lower than a threshold value level, a reference voltage circuit 13 biases a control circuit 12 so that the switch device Q1 continues a current IOUT. The switch device Q1 continues it until the rectified voltage waveform VOUT is over the threshold value. An output voltage VOUT is limited by resistance feedback R6 connected to the reference voltage circuit 13 from the output of the power source. The resistance value of a feedback line exerts on influence on the threshold value level and the peak amplitude of a current pulse continued by the switch device Q1.

Title: Chain
Inventor: NAKAMURA JIRO
IPC: F16G13/02
Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To enable supply of lubricating oil for long period of time with a simple shape, yet with less likelihood of producing rattles. SOLUTION: Intended lubrication is performed by supplying oil toward a joint pin 7 and allowing the lubricating oil to move to the joint pin 7 portion. Part of the supplied lubricating oil adheres to a recessed surface of a recess 11 and does not immediately flow down because of frictional resistance and surface tension on the recessed surface and maintains its adhering state. As the chain 1 moves, the lubricating oil gradually flows down and is used for lubrication. Thus, the joint pin 7 of the chain 1 remains in a state of being supplied with oil for a long period of time after passing the oil supply portion.

Abstract: PURPOSE:To make a high-quality color image, by setting the thickness of a light-permeable electroconductive film within a prescribed range for a photoconductive target made of amorphous silicon as the main constituent, to heighten the sensitivity to blue light. CONSTITUTION:In a photoconductive pickup tube, a light-permeable electroconductive film 2 made of at least SnO2 as the main constituent and a photoconductive amorphous film 4 having 50% or more by atom of silicon and containing 5 to 50% by atom of hydrogen are provided on a light-permeable base plate 1.
