Title: Dicing device
Inventor: YOSHIMURA KATSUNOBU
IPC: H01L21/78
Filed: 1980-06-06
Abstract: PURPOSE:To improve the yield of a dicing device by dicing a wafer in the state disposed in pure water, thereby preventing the breakdown of an IC with static electricity of fog of the pure water charged by static voltage. CONSTITUTION:A dicing work is performed in pure water 8 in a water tank 7. Since the lower half of a dicing blade 5 and a wafer 6 are completely submerged under water in this manner, they can be completely isolated from the fog changed with generated static electricity. Since the environment of the water tank 7 is formed of grounded conductive material, the static electricity can be readily discharged, with the result that the static voltage is not so raised. Accordingly, it can effectively prevent the breakdown of an MOS field effect IC or the like due to the static electricity.

SOLUTION: When an inquiry key is operated (S1), a radio part starts the connection of a channel to a radio base station (S2). When the connection of channel is started, a table number is inputted via a keyboard (S3). Then an ENT key is operated (S4), and a transmission key is operated (S5). Thus, the connection of channel is confirmed. When the connection of channel is completed, the table number and the data on an inquiry message are sent by radio to a system controller via the radio base station (S6). A radio portable terminal unit receives the inquiry data (S8), disconnects the channel (S9) and shows the inquiry data on a display (10). Since the connection of channel is completed at the time the data are transmitted by radio, the communication efficiency is improved.

Title: Helical spring
Inventor: SAITOU SUMIYUKI
IPC: F16F1/04
Filed: 1983-05-04
Abstract: PURPOSE:To provide a helical spring of long life, by shaping the cross section of a spring wire as an egg resulting from a combination of a semicircle and a semi-ellipse and by setting the ratio of the diameter of the semicircle to the major diameter of the semi-ellipse and the spring constant at prescribed values, respectively, to reduce stress concentration. CONSTITUTION:The cross section of a wire for a helical spring is shaped as a semicircle for the outer portion of the coil and a semi-ellipse which is for the inner portion of the coil and has a minor diameter equal to the diameter B of the semicircle. The ratio A/B of the major diameter A of the egg-shaped cross section of the wire to the diamter B of the semi circle is set at 1.1 or more. The spring constant (k) is determined as k=GB<4>{(2-128/9pi<2>(A/B)<3>-(3- 256/9pi<2>)(A/B)<2>+(2-128/9pi<2>)(A/B)}/8nD<3> where G denotes the modulus of rigidity, (n) the effective number of turns, and D the diameter of the coil on the center of gravity of the cross section. As a result, even if the helical spring is made of a wire with a large ratio A/B, the stress concentration in the inner portion of the coil is well reduced to lengthen the life of the coil.
