Title: Device for measuring length of body
Inventor: ARITA SADAO
IPC: G01B21/02
Filed: 1986-12-04
Abstract: PURPOSE:To easily measure the length of a body to be measured by one length measuring person without being restricted by the size of the body to be measured, by providing the measuring roller part contacting the body to be measured and a measuring switch for indicating measurement. CONSTITUTION:A measuring person brings a measuring roller part 1 into contacts with the measuring part of a body 10 to be measured and moves the same under rotation. A measuring switch 2 is operated when the roller part 1 contacts a measuring start point and when said roller part 1 contacts a measuring finish point to apply a measuring indication signal to a moving distance operation part 4. At this time, the angle formed by the roller rotation detection part 3 supporting the roller part 1 and the body 10 coincides at both measuring start and finish points. The detection part 3 detects the number of rotations of the roller part 1, for example, by a rotary encoder to output the same to the operation part 4. By this method, the moving distance of the body to be measured, that is, the length thereof is operated on the basis of the product of the number-of-rotation signal of the measuring roller outputted from the detection part 3 and the outer periphery of the roller part 1 calculated from the known radius thereof by the operation part 4 and the operation result is displayed on a display device 5 as the length of the body to be measured.

Title: Cold accumulation type refrigerator
Inventor: FUJIMOTO SHINJI
IPC: F25D11/00
Filed: 1987-11-17
Abstract: PURPOSE: To simultaneously satisfy functions as a cold storage and a refrigerator by bending zigzag a cooling pipe on the same plane and allowing the pipe to stick to a wall surface part facing the inside of a cold storage reservoir by a fixing metal fitting with a heat transfer fin in an upper direction. CONSTITUTION: When a compressor 12 is operated, cooling operation is started, a cold storage agent 16 being filled into a cold storage reservoir 9 starts to be frozen by a cooling pipe 15, and at the same time the inside of the cold storage bath is forcibly cooled via a lower wall 9b. In this case, even if separation is made from a power supply, the cold insulation can be made for a specific amount of time in the reservoir due to the melting latent heat of the cold storage agent 16. Also, when power is turned on, cold insulation goods being stored in the cold storage reservoir can be efficiently and rapidly cooled due to natural convection since a lower wall 9b of the cold storage reservoir 9 where the cooling pipe 15 adheres to is located inside the cold storage bath.  Further, the cold storage agent 16 is frozen from the surrounding of the cooling pipe 15 and heat travel becomes insufficient. However, since heat is transferred by a heat transfer fin part 17b being fixed to the cooling pipe 15, the upper cold storage agent 16 can be efficiently and positively frozen to the center of the cold storage reservoir 9, thus extending freezing time.

Abstract: PURPOSE: To make contact failure between a contact pin and a lead hardly occur and surely keep stability of electric contact by bringing a contact part of the contact pin into contact with the lower face of a lead with a gull wing- type structure of a semiconductor device. CONSTITUTION: A contact pin 15 is composed of a pin main body 16, a sagging margin part 17 ranging from the main body 16 and so curved as to be U-shaped toward a side, and a contact part 18 which ranges from the part 17 and is to be brought into contact with a lead 9. Since the part 18 is made to be an arc-like shape, the part can brought into contact with the lower face of a gull wing-type lead 9 and the friction degree due to sagging of the part 17 becomes (a) and (a) can be made bigger than the upper face of the lead 9. That is, the friction degree, which is about 0.1mm conventionally, can be made as big as 0.5mm. In this way, by making the friction degree big, cleaning effect can be expected, so that oxides produced in the surface of the lead 9 can be removed and reliable electric contact can be obtained. As a result, stability of electric contact can be retained surely.
