Title: High-speed backward travel restraining structure for walking type work machine
Inventor: FUJIMOTO SATOSHI
IPC: B60K20/00
Filed: 1993-05-17
Abstract: PURPOSE:To enable high-speed backward travel to be restrained with simple and inexpensive constitution, regardless of a change in the steering direction of a handle by causing a restraining fixture operated for oscillation with a sub-transmission lever to selectively come in contact with the forward and backward travel shift shafts of a main transmission device. CONSTITUTION:Recesses 6b and 7b are formed on shift lever rests 6a and 7a at the ends of respective shift shafts 6 and 7 to perform the control of forward and backward travel at high and low speed. A restraining fixture 13 engaged with or disengaged from each of the recesses 6b and 7b is laid so as to be operable in unison with a sub-transmission lever 10. In this case, when the lever 10 is shifted to a high speed position with the backward travel shift shaft 7 kept at a neutral position, the fixture 13 is coupled to the recess 7b, thereby prohibiting the shift of the backward travel shift shaft 7 to a speed change position. On the other hand, when the lever 10 is shifted to a low speed position, the fixture 13 is disengaged from the recess 7, thereby allowing the shaft 7 to be shifted to a speed change position.

Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of defective fixing at the time of repeated copying caused by the partial lowering of paper temperature at a nip part between a fixing roller and a pressure roller at a fixing device. SOLUTION: As for the fixing device provided with the pressure roller 3 and the fixing roller 2 with a built-in heat source 1; the pressure roller 3 is formed of heat-resistant film 4a, a metal layer 8a, an outside chamber 7, the metal layer 8b, the heat-resistant film 4b and an inside chamber 6 in order toward inside from a surface layer part, and the inside and outside chambers are filled with gas whose coefficient of thermal expansion is positive. A switch mechanism is constituted of the metal layers 8a and 8b, and communicates with the heat source 1 of the fixing roller through a temperature control circuit.  The metal layers 8a and 8b are brought into contact with each other when the temperature of the pressure roller 3 is lowered because heat is taken away by the paper at the time of the repeated copying, so that the temperature of the heat source 1 is raised by the temperature control circuit. Thus, cold offsetting caused by the lowering of the surface temperature of the pressure roller is prevented.

Abstract: PURPOSE: To regularly keep a heat absorbing part in a low temperature state by separately setting the heat absorbing part (ice pillow part) and a heat source part (ice input part), and mutually connecting the both to circulate a refrigerant. CONSTITUTION: When cold water is poured into a heat source part 2 set in a position higher than a heat absorbing part (ice pillow part) 1, the cold water is supplied to the heat absorbing part 1 formed, for example, into a hollowed ring through a cold water supplying hose 3 to cool a part to be cooled such as head part of a patient 7.

Abstract: PURPOSE:To make possible the assurance of the vacuum evacuation time in the die casting stage to the max. possible extent by providing a vacuum valve having a check mechanism for which a thermal deforming member having high sensitivity into a gas vent passage provided via a pouring basin to a die cavity. CONSTITUTION:The inside of the cavity 18 is forcibly evacuated while the evacuation passage 50 of the vacuum valve 38 is held communicated with a vacuum tank 72 via the gas vent passage 44 and a selector valve 70. The thermal deforming member 62 is deformed when part of the molten metal poured into the cavity contacts with a surface part 46 for transmitting the head of the die in the pouring basin 42. The engagement of a link member 60 and a valve disk 56 is then released and the disk 56 is pressed by a spring 54 to a valve seat 58, by which the passage 50 is shut off. The member 60 is engaged with the disk 56 by a piston 66 and depresses the disk when a pressurizing device 76 is communicated via a selector valve 74 to a bypass 65 in the stage of restoring the original shape of the member 62 upon cooling. The assurance of the vacuum evacuation time to the max. possible extent is thus made possible in the stage of pouring the molten metal into the cavity.

Filed: 1990-05-01
Abstract: PURPOSE:To execute a uniform corona discharge between the front ends of needle-like discharge electrodes and the peripheral edges of vent hole and to improve dust collection efficiency by disposing plural pieces of the vent holes to the waveform flat side faces of partition plates and successively providing the needle-like electrodes facing the vent holes at the front ends of the repulsion electrodes provided in parallel with dust precipitating electrodes. CONSTITUTION:Plural pieces of the vent holes 4 are disposed without intersecting with each other on the flat side faces of the waveform partition plates 3 and the needle-like electrodes 14 are connected to the font ends of the repulsion electrodes 9 extended near to the top parts of the partition plates 3 in parallel with the dust precipitating electrodes 10 by directing the front ends of the discharge toward the vent holes 4. The dust in air is exposed to the corona wind radiated from the front ends of the needle-like electrodes 14 toward the inner edges of the vent holes 4 and is electrified at the time of passing the vent holes 4 when the dusty air is fed into the precipitator from the arrow direction under the impression of a high voltage thereto. The dust is repulsed by the repulsion electrodes 9, after the passage through the vent holes 4, and is captured on the dust precipitating electrodes 10 while flowing in the form of laminar flow. The cleaned air is diffused from a lower aperture to the outside. The degradation in the dust collecting performance by the unequal discharge occurring in the turbulence of the dusty air is obviated in this way.
