Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To obtain a wood plastic which can widely be used similarly to ordinary resin raw materials, by mixing different kinds of resins with a lignin component-containing substance and then applying a prescribed processing to the mixture. SOLUTION: This wood plastic is obtained by subjecting a mixture of (A) at least two different kinds of resins 12, 14 (for example, the wastes of a resin such as a polyurethane, a resin mixture such as shredder dust) with (B) a lignin component-containing substance (for example, bamboo scraps) 16 to a high temperature high pressure treatment. Thereby, steam is generated from the component B 16, and lignin 18 is extracted from the component B 16 by the action of the steam. The extracted lignin acts as a solubilizing agent to solubilize the components A 12, 14 each other. Thus, the wood plastic which has a strong bonding force by the synergistic action of both the chemical and physical bonding forces and can exhibit an excellent quality due to the good physical values can easily be provided.

Title: Reciprocating type compressor
Inventor: KOBAYASHI HISAO
IPC: F04B27/14
Filed: 1984-08-30
Abstract: PURPOSE:To aim at relaxing starting shocks, by providing such an arrangement that discharge pressure is applied to a rear surface chamber in a bypass change-over valve through constricting passages to hold this valve at its normal blocking position during operation of a compressor so that a compression chamber is set to be in such a condition that no compression work is effected. CONSTITUTION:Discharged gas flowing from a compression chamber 16 and discharged through discharged ports 36, 37 into discharge chambers 22, 23 and discharge gas fed from the front side discharge chamber 22 into the discharge chamber 23 through a discharge passage, are merged into a gas stream in the direction identical with the moving direction of a bypass change-over valve 52 when the stream flows down to a bypass passage 48. This gas stream gives an acting force to the bypass change-over valve 52 which is thereby attracted toward the valve plate 4 side. However, in the bypass change-over valve 52, since its rear surface chamber is communicated with the discharge chambers 22, 23 only through constricting passages 59, 60, the pressure of the rear surface chamber becomes negative so that the change- over valve 52 moderately moves toward a position where the change-over valve 52 moderately moves toward a position where the change-over valve 52 blocks the passage 48, at a speed corresponding to the amount of suction gas from the constricting passages 59, 60, overcoming the urging force of a spring 54, thereby the discharge pressures in the discharge chambers 22, 23 are gradually raised to relax the starting shock of the compressor.

Filed: 1991-07-19
Abstract: PURPOSE:To ensure specified thickness for paint film and to eliminate duplication of coating or leaving of uncoated surface in coating of external wall surface with transparent coating material. CONSTITUTION:Transparent coating material is colored by adding a fugitive coloring matter material. A part of external wall surface is coated with the colored transparent coating material and the part is made colored surface. Thereby the coated part becomes distinguishable from uncoated part.

Title: Read/write system for semiconductor memory
Inventor: MATSUO HIDENORI
IPC: G06F9/52
Filed: 1990-07-09
Abstract: PURPOSE:To shorten the access time by connecting a timer to a preference control part and ending forcibly an access when a timer has a time-up state. CONSTITUTION:When a timer 8 is set in a time-over state after a set time, the timer 8 outputs an access end signal to a preference control part 6 to instruct the forcible end of an access. The part 6 receives the access end signal and ends the access given from a 1st CPU 1, for example, and transfers the access right to a 2nd CPU 2 if an access signal Sb is outputted from the CPU 2. The timer 8 starts again its counting action after the access right is received by the CPU 2. However, the set time of the timer 8 is slightly longer than the time during which both data write/read operations of both CPU 1 and 2 are through to a semiconductor memory 7.

Title: Driving circuit for multi-nozzle ink jet printer
Inventor: MATSUOKA TAKAO
IPC: B41J2/055
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To prevent mutual interference of nozzles by connecting one electrode of a piezoelectric element to a common electrode, providing a voltage control means of the common electrode and a current sensing means for sensing current flowing to the common electrode, sensing number of the simultaneously driving nozzles by the current sensing means, and altering a voltage of the common electrode according to the sensed result. SOLUTION: When an output signal OE is sent to a data selector 23 after a DATA signal is sent to the selector 23, n sets of transistor pairs 21a to 22n change ON/OFF states in response to received data. For example, when the transistors 21a, 22a are respectively changed from ON to OFF and OFF to ON, a voltage applied to a piezoelectric element 20a is eliminated. At this time, current supplied to the element 20a flows to a transistor 27. Thus, a value of the current flowing to the transistor 27 increases in proportion to number of nozzles driven simultaneously. And, a peak of the current value is held, added to a previously set set value by an adder 25, thereby raising an output voltage of a transistor 26.
