Title: Pneumatic tire
Inventor: KUBOTA HITOSHI
IPC: B60C5/22
Filed: 1982-03-02
Abstract: PURPOSE:To make the regulation of air pressure unnecessary for a long time in a  double structure pneumatic tire whose inside is divided radially by a partition wall into  an inner and an outer chamber by providing a regulation valve to be opened and  closed in accordance with the pressure in the outer chamber on the partition wall. CONSTITUTION:High pressure air is at first injected into the second air chamber 15 via  a valve 16. At this stage, since the first air chamber 14 is under an atmospheric air  pressure, a spool 20 is pushed to the side of a port 29 by a spring 30 and the inner pressure of a small chamber 22 for separating a valve body 27 from a valve seat 26. Consequently, the high pressure air is also introduced into the side of the first air chamber  14 for increasing the pressure inside. When the inside of the first air chamber 14 comes  to a fixed pressure, the spool 20 is pushed to seat the valve body 27 on the valve seat  26, and the introduction of the high pressure air into the first air chamber 14 is intercepted. The air is furthermore injected into the second air chamber 15 to obtain high  pressure. When the pressure in the first air chamber 14 is lowered under a fixed value,  the valve body 27 is opened to supply air from the second air chamber 15, and the pressure is maintained at a fixed level. This construction permits to make the regulation  of pressure unnecessary for a long time.

CONSTITUTION:When a pipe 3 is damaged, the sediment over the upper side of the pipe 3 is digged temporarily and exposed, and the damaged portion of the pipe 3 is located and the damaged condition is confirmed. Then the upper side of the pipe 3 is restored temporarily to prevent trouble due to traffic, etc. In performing temporary restoring a semicircular groove 9 having a radius (r) corresponding to the outside diameter of the pipe 3 is formed on a frame 7a made of foam styrene block, which is set on the upper side of the exposed pipe 3. First, the falsework 7a is positioned and worked according to the size of the groove 2 digged temporarily. The form 9 is positioned so that the groove 9 may be applied tightly on the upper surface of the pipe 3. Then multiple forms 7b, 7c made of foam styrene block the upper and lower surfaces of which are formed flat, are stacked according to the degree of each covering depth over the buried pipe 3, and then the top of the groove 2 is covered by a protective steel plate 10. As a result, temporary restoring is completed.

IPC: F24C1/00
Filed: 1982-03-03
Abstract: PURPOSE:To permit an error-free and precise cooking result without being influenced by a variable illumination, by controlling a heating source upon an illumination of reflecting beam being elevated to a predetermined value at a certain fixed point of cooking object. CONSTITUTION:By turning ON an electric power unit 34 for actuating electric heaters 7a-7d, a lamp 11 goes ON and a visible light is illuminated to a food 2 through an opening 17 and a glass plate 18, while a motor 6 is caused to operate and a fan 28 starts an air blowing function. At this moment, a light receiving element 19 detects a light reflected from a food surface through glass plates 24 and 25 and an opening 26. A synchronous detecting timing by the light receiving element 19 with a rotating cycle which is separately measured can enable one changing cycle of this signal to be in harmony with one rotation of turn table. When a food 2 surface is browned by a high temperature atmosphere inside a heating chamber 1 and an infra-red ray energy generated by electric heaters 7a-7d as the heating time passes, the detecting signal with the cycle as above mentioned instructs an electric power source to make the electric heaters 7a-7d and also the lamp 11 inoperative.
