Title: Stylus support device
Inventor: HIDAKA KAZUHIKO
IPC: G01B21/00
Filed: 1995-05-11
Abstract: PURPOSE: To improve the reset position accuracy of a stylus,.and at the same time, miniaturize a stylus support device by supporting the stylus at both sides using an elastic hinge and hence eliminating the influence of friction and a complex elastic deformation. CONSTITUTION: When a stylus 7 contacts an object to be measured and external force is acts on the stylus, 6-node motion mechanisms 10 and 20 operate and hence the stylus 7 is inclined and performs an escape action. For example, when external force along the longitudinal direction of the mechanism 20 acts on the stylus 7, elastic deformation rotary shafts 21A-26A of the elastic hinges 21-26 properly rotate and a middle part 4 travels on a plane which crosses six parallel rotary shafts 21A-26A which the mechanism 20 has for a reference part 2. In this case, unless external force in the longitudinal direction of the mechanism 10 it acts on the stylus 7, the middle part 4 and the displacement part 3 move in one piece so that the displacement part 3, namely the stylus 7, also travels within a plane which crosses the rotary shafts 21A-26A for the reference part 2.  The hinges 11-16 and 21-26 and links 31-34 and 41-44 can be constituted flush with each other, this reducing the height dimension.

Filed: 1992-05-06
Abstract: PURPOSE:To provide a fuel cell having a liquid flow plate, allowing mass production while light weight and mechanical strength being maintained, by forming the separation section of a cell with an insulator, and providing a conductive section through the separation section. CONSTITUTION:A cell is constituted of a cathode 3 and anode 4 where an electrolytic body 5 is inserted. An insulator such as a plastic material forms a separation section 31 to separate fuel from an oxidant supplied to the electrode section of the cell. Also, a part 33 of the separation section 31 forms a liquid flow plate. In addition, a plurality of conductive sections 32 are formed through the part 33. A fuel cell is thus formed with a plurality of the cells. As the separation section 31 is made of an insulator, weight does not become large as in the case where a conductive material is used. Also, the shortage of mechanical strength as in the use of a carbon material for weight reduction can be prevented. Accordingly, a fuel cell having a liquid flow plate can be provided, allowing mass production while light weight and mechanical strength are maintained.
