Then the output of each sensor is amplified through operational amplifiers 61-63 to obtain outputs A'-C' each. The difference between signals A' and B' as well as between B' and C' is detected through operational amplifiers 64 and 65 each, and the output signals D and E are supplied to exclusive OR circuit 67 in order to obtain element clock pulse F featuring double density to the fixed pitch. In this case, the electric bias amount is fixed for amplifiers 62 and 63, and the control is given only to the bias amount of amplifier 61. As a result, the phase control can be facilitated, thus reducing the control time.

IPC: F02B75/02
Filed: 1982-03-05
Abstract: PURPOSE:To improve an energy-utilizing efficiency of an engine through introduction of exhaust gas to a secondary expansion cylinder, by locating the secondary expansion cylinder in a middle position between two cylinders of a 2- cylinder 4-cycle engine. CONSTITUTION:A secondary expansion cylinder 3 is located in a middle position between two cylinders 1 and 2 of a 4-cycle engine. Exhaust paths 6 and 7 are open to the secondary expansion cylinder 3.

Title: Cracking inspection for concrete
Inventor: HASHIMOTO KAZUO
IPC: G01N21/91
Filed: 1987-02-19
Abstract: PURPOSE:To enable detection of even an invisible fine cracking, by applying a transparent fluorescent liquid on the surface of concrete in a uniform film to irradiate an ultraviolet black light to the surface thereof after a required time passes. CONSTITUTION:When ultraviolet black light is irradiated before a fluorescent liquid 3 is absorbed into concrete 1, it looks bright in bluish green at a sound portion 4 thereof without cracking. By contrast, the film of the fluorescent liquid 3 breaks on the edge of the cracking 5 at a portion with a relatively broad cracking 5 because of weak capillarity; it fails to light, looking dark even by the ultraviolet black light and hence, the cracking can be detected clearly. On the other hand, at a fine cracking 6 portion, intense capillarity causes the ambient fluorescent liquid 3 to be absorbed into the concrete 1. It looks dim in an intermediate range between the sound portion 4 and the cracking portion 5, hence visually recognized. Thus, the sound portion 4 and cracking portions 5 and 6 are visually recognized thereby enabling detection thereof.
