Title: Focus error detector
Inventor: AIKO HIDEKI
IPC: G02B7/28
Filed: 1988-09-30
Abstract: PURPOSE:To stably detect a focus error signal without a light quantity loss by setting the positions of quadrisected photodetectors in such a manner that the light quantities in four photodetecting regions are equaled, summing the electric signals generated in the diagonal positions of the four photodetecting regions and obtaining the differences therefrom by a differential amplifier. CONSTITUTION:Two semicircular light spots of approximately the same congruence, the same direction and the same light quantity are formed on the quadrisected photodetectors 7 by a convex lens 5a and a prism 6. The positions of the quadrisected photodetectors 7 are so set that the light quantities received by the four photodetecting regions of the quadrisected photodetectors 7 are equaled. The electric signals generated by the diagonal regions of the four photodetecting regions of the quadrisected photodetectors 7 are summed and the differences thereof are determined by the differential amplifier 8. The stable focus error signal which eliminates the light quantity loss and is not affected by the microdisplacement of the quadrisected photodetectors 7 is detected in this way.

Title: Data signal transmission reception system
Inventor: WAKATSUKI TAKASHI
IPC: H04L7/00
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To eliminate manual operation by deciding the phase of a data identification clock signal automatically caused by the delay in a transmission line in the transmission reception system where data are sent synchronously with a clock signal from a receiver side and received data are identified and latched by the clock signal of its own equipment at the receiver side. SOLUTION: A counter 1 counts a prescribed time just after the system is started, a clock signal from a transmitter side 100 is looped back for that time and sent to a receiver side 200. A phase difference detection circuit 11 at the receiver side detects a phase difference between the looped-back clock signal and the clock signal in its own equipment to detect the delay in a transmission line 300. A selector 16 selects automatically whether the output of a latch FF12 by the noninverting clock signal or outputs of latches FF13, 15 by an inverted clock signal.

Title: Self-priming pump
Inventor: ARAOKA TOSHINOBU
IPC: F04D9/02
Filed: 1993-10-04
Abstract: PURPOSE:To provide a self-priming pump that is effectively usable as a sand feeding pump or the like. CONSTITUTION:In a self-priming pump P being made up of connecting a suction pipe 17 to a suction opening of an impeller casing 11, ans also connecting a discharge pipe 19 to the discharge opening, a reserve water tank 14 is installed in a position where the impeller casing 11 get closer, and this reserve water tank 14 and a terminal part of the suction pipe 17 are connected to each other via a reserve water feed passage, and further a spot midway in the discharge pipe 19 is connected to the tank 14 via a reserve water reflux passage. Thus, since a reserve water chamber is not formed as a front inflow chamber of the impeller casing 11 but made up as a separate body, when operation of this self-priming pump P is stopped, earth and sand or the like in the discharge pipe 19 will not flow in the reserve water chamber even if it flows back to the inside of the impeller casing 11, so that abrasion and damage to a side wall and a bottom wall due to a sediment inflow into the reserve water chamber is surely preventable from occurring. On the other hand, reserve water is flowable back to the reserve water chamber through a reserve water reflux passage, so sufficient reserve water is always securable in the reserve water chamber.
