Title: Brake device for single-acting cylinder
Inventor: YODA AKIRA
IPC: F15B15/22
Filed: 1979-12-07
Abstract: PURPOSE: To permit reliable and ready action of braking the single-acting cylinder piston at the time of unloading and also prevent unnecessary movement of the piston beyond the stroke as in the prior art.  
     CONSTITUTION: A contactor 8 provided at the tip with a throttle hole 9 is installed in an unload valve 5, and the whole system is slidably fitted in a piston 2. A mirror plate 17 of the cylinder 1 has an operating fluid outlet 4 formed at a position substantially aligned to the contactor 8. When the contactor 8 contacts the mirror plate 17 at the end of the outgoing motion of the piston 2, the unload valve 5 is opened, causing the escapement of the operating fluid through passages 6 and 7 to the outlet 4. At the same time, the operating fluid on the back of the piston narrowly escapes through the throttle hole 9, but the pressure is temporarily increased. Thus, it is possible to obtain reliable braking action on the piston 2 at the time of unloading.

Title: Probe
Inventor: SUZUKI YOSHIHIRO
IPC: G01R13/20
Filed: 1987-06-25
Abstract: PURPOSE:To prevent the malfunction and breakdown of a measuring target by coating the side of a contactor where the contactor does not come into contact with the measuring target with an insulating material. CONSTITUTION:A contactor cover 2 is retreated by overcoming the elasticity of a spring to project the contactor 3 forward of the cover 2. A pin of an LSI or the like which is the contact target is pinched by the exposed part of the metallic wire on the inside and the cover 2 and is measured. The outside of the contactor 3, i.e., the side where the contactor does not come into contact with the measuring target is coated with the insulating material 5 and, therefore, the insulating material 5 comes into contact with the adjacent pins and the short circuiting of the pin which is the measuring target and the adjacent pins is prevented even during the energization. The malfunction or breakdown of the measuring target is thus prevented and the measurement operation is facilitated.

IPC: B60N2/48
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To enable the fitting of a shopping bag or the like by integrally forming an under cover, which is fixed to a lower surface of the head rest, with a hook stood from a back surface of the head rest. SOLUTION: An under cover 6, which is fixed to a lower surface of a head rest 4, is integrally formed with a hook 9 stood from a back surface 8 of the head rest 4. A loop part 14 of a shopping bag 13 can be hooked on this hook 9. The shopping bag 13 hooked on the hook 9 is stabilized in the condition that the shopping bag 13 is suspended from the hook 9 by the weight of itself. Since a seat back 3 is inclined backward, the shopping bag 13 is hard to abut on the back surface of the seat back 3, and the movement of goods inside of the shopping bag 13 is constrained by the tensile force of the shopping bag 13 itself. Consequently, the shopping bag 13 is hard to be fallen and the goods inside of the shopping bag 13 is hard to move inside of the bag 13, and generation of breakdown and deformation of the goods is prevented.

Filed: 1987-06-25
Abstract: PURPOSE:To enable lighting even if automatic lighting and ambient illumination are below the standard by turning on a lighting fixture when a human body detection signal and a low-illumination detection signal are received and until a preset time passes after a lighting command signal is received from a manual switching means. CONSTITUTION:When the circumference is dark and a person enters a detection region of human body detection means (human sensor) 12 and 22, a controlling means 17 receives human body detection signals from the human body detection means 12 and 22 and receives low-illumination detection signals from illumination detection means (illumination sensors) 13 and 23, so that lighting fixtures 10 and 20 are turned on. Even if the low illumination detection signals are not outputted from the illumination detection signals 13 and 23 in the evening or so, the lighting fixtures 10 and 20 are turned until a preset time passes when the controlling means 17 receives a lighting command signal from a manual switching means 30. Otherwise, the lighting fixtures 10 and 20 are controlled to be on states lower in their brightness than on the lighting states, or to be on putting-out states. Automatically lighting control of the lighting fixtures can be thus performed, and also they can be turned on even in case of unsatisfied lighting conditions.

Title: Separator
Inventor: KUMAI SEIJI
IPC: B65G47/78
Filed: 1981-10-06
Abstract: PURPOSE:To provide a separator with a buffer member secured to a pusher and adapted to apply component force to a transported article in the direction of transportation by forward movement of the pusher so as to attain reliable separation. CONSTITUTION:A pusher 4 is moved backward, and a stopper 3 is projected below a transport path 1 so as to supply a plurality of transported articles 2 to the transport path 1. At this time, a buffer member 6 is oval and the end portion A thereof is separated from the transported article 2b. After that, the pusher 4 is operated so that the buffer member 6 pushes the transported article 2b and the stopper 3 is detached. At this time, the projection of the pusher 4 causes an O-ring 7 to deform at a point A where the ring is first brought into contact with the transported article an to be substantially L-shaped, so that component force of the arrow direction is applied to the transported article 2b. Therefore, the lowermost transported article 2a, which is about to be lifted up together with the upper transported article 2b, is separated from the transported article 2b to be lowered by its dead load and friction between the article and the transport path 1.

Title: Deep freezer
Inventor: SAITO KATSUMI
IPC: F25D13/06
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To increase a width of a conveyor without increasing a volume of a freezing chamber or raising an installing height of a housing by forming a sectional shape of an inner surface of a direction perpendicular to a lengthwise direction of a housing in an elliptical shape or a shape similar to the elliptical shape. SOLUTION: Material conveyed by a conveyor 1 is frozen by cooling air supplied by a cooling unit 15. At this time, since a housing 2 is formed in an elliptical shape, cooling air smoothly flows in a freezing chamber similar to a true circle shape, the cooling air efficiently heat exchanges with a the material to efficiently freeze it. Even if a width (a) of the conveyor 1 is widened to direct freezing of a large quantity, an installing width (b) of the housing 2 becomes wide due to the elliptical shape of the housing 2, but installing height (c) of the housing does not so become high due to the width (b). Therefore, a decrease of a thermal efficiency of the freezing due to the increase of the volume of the chamber is eliminated.
