Title: Two-pipe type vapor central heating device
Inventor: OOMORI TOSHIAKI
IPC: F22B35/00
Filed: 1984-03-30
Abstract: PURPOSE:To contrive to improve the usability of each radiator by a method wherein the heat transmission is performed by utilizing vapor and the reflux of liquid is performed by utilizing the vacuum action so as to reflux the condensate stored in condensate reservoirs to store in a common condensate reservoir. CONSTITUTION:A check valve 15, which is mounted on a liquid return pipe 14 connecting the interior of a vapor generator 1 with a condensate reservoir 13 in the title central heating device, is of normally closed type and is open to the vapor generator 1 side when the pressure in the vapor generator becomes low. The saturated vapor produced in the vapor generator 1 condenses at the radiating coil 8 of each radiator 7 and flows through each condensate branch pipe 11 into a condensate main pipe 12 in order to be stored in the condensate reservoir 13. When the liquid level in the vapor generator 1 lowers, a low liquid level sensor 3 detects the lowering of the level and outputs an OFF signal to a control valve 17 so as to stop the actuation of a heating source 2. Accordingly, the vapor in the vapor generator 1 condenses and consequently vacuum is produced in the vapor generator 1, resulting in refluxing the condensate stored in the condensate reservoir 13 through a liquid return pipe 14 to the vapor generator 1. After that, when the liquid level in the vapor generator 1 rises again, an ON signal is sent to the control valve 17 so as to start the actuation of the heating source 2.

Title: Rear frame mounting structure of motorcycle
IPC: B62K19/24
Filed: 1992-03-18
Abstract: PURPOSE:To improve mounting precision of a rear frame by locking together a main frame and a seat rail by means of a screw, and fixing a round hole and an oblong hole by means of a bolt and nut. CONSTITUTION:The round hole A1 of a main frame 5 is caused to coincide with the round screw A2 of a seat rail 21 and fixed by means of a screw. The round screw holes B1 and E1 of the main frame 5 are caused to coincide with the round hole B2 and the oblong hole E2 of a foot rest bracket 25 and fixed by means of a screw. In this state, jolting of the foot rest bracket 25 is absorbed only in a direction Y owing to the presence of the oblong hole E2. Thereafter, the round hole C2 of a back stay 22 is caused to coincide with the oblong hole C1 of the foot rest bracket 25 and fixed by means of a bolt and a nut. In this case, movement only in a direction X is practical owing to the presence of the oblong hole C1 and thus, the rear end D point of a rear frame 6 is prevented from vertical jolting.

Abstract: PURPOSE:To provide a bag which can be opened by being smoothly torn from its back seal notch part by providing a tear notch in the back seal part formed of the material laminating in layers a laterally uniaxial stretched plastic film and a plastic film having a specific ability of an easily cohesive failing and peeling. CONSTITUTION:A tear notch 3 is provided in a back seal part 1 formed of the material laminating in layers a laterally uniaxial stretched plastic film A and a plastic film B having an easily cohesive failing and peeling ability at a heat sealing strength of 0.5-2.0kg/15mm. By imposing a stress on the same line in reverse directions from (a) and (b) with the notch 3 as a center, a tear takes place in the width direction (c) of the back seal part and continues toward a sealing field (d), i.e. since the stress is worked on the tear deviation instead of a cohesive failing force, a suitable stress causes the tear to restart at the tear deviation and progress toward (d1) and (d2), leading to a smooth bag opening. This provides a bag which can be opened by being smoothly torn from the back seal notch part.

Title: Disk brake
Inventor: YAMAGUCHI TOUMA
IPC: F16D65/18
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To maintain a favorable positional relation between a motor rotor and a screw shaft even during replacement of a brake pad. SOLUTION: A caliper 3 is formed in the inner surface of its cylinder- extension part 31 with a line of axial groove 42, and a detent plate 33 having a projection 41 to be inserted into this groove 42 is mounted on the end of a screw shaft 8 distant from a pad 10 to regulate the rotation of the screw shaft 8 via the detent plate 33. Characteristically, the screw shaft 8 is not coupled to an inner pad 10a via any detent means. By this construction, even if a braking operation in which a brake rotor 9 has sliding movement causes the inner pad 10a to play at a carrier 2, the backlash is never transmitted to the screw shaft 8, which is therefore prevented from having any reciprocation amount deviation of the screw shaft 8.
