Title: Cathode-ray tube with contact spring
Inventor: BUCHER ALAN WEIR
IPC: H01J29/06
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To facilitate insertion of a contact spring and simplify its design by engaging a hook with an outer edge of a land, engaging a latch with an inner edge of the land, and extending a spring plate part connected to the latch from the latch. SOLUTION: A repeated bend hook 46 of a contact spring 28 is engaged with the outer edge of a land of a shield 18, and a latch 48 is engaged in an opening 34 with the inner edge of the land of the shield 18. When the contact spring 28 is installed, the hook 46 is installed first and acts as a pivot for rotating the contact spring 28, and the latch 48 enters the opening 34 and engages with the inner edge of the land of the shield 18. The mutual interaction of a clamp part of the contact spring 28 with a rear part of the shield 18 gives a self-tightening feature, when a plate part of the contact spring makes contact with a conductive coating on an inner wall of a funnel. The plate part of the contact spring, when it makes contact with the interior of the funnel, is deflected towards the shield 18 so as to further close the clamp part around the inner and outer edges of the land.

Title: Optical distance measuring
Inventor: TAKADA YUJI
IPC: G01S17/36
Filed: 1989-09-26
Abstract: PURPOSE:To make it possible to prevent erroneous measurement of a distance due to induced noise signals by setting the shift phase and the level of a shift reference signal so that the induced noise signals are cancelled, and adding the shift reference signal to the output of a first photodetector. CONSTITUTION:The phase of a reference signal f0 is shifted, and shift reference signal is outputted from a phase shift circuit 13. The shift reference signal is added to the output of a first photodetector 5a and the result is outputted to a first mixer circuit 9a with an adder 7. The circuit 13 and the adder 7 are provided in this way. When a body to be detected X is not present, the output of the circuit 13 is set so that phase is reverse to the phase of the induced noise signal outputted from an I/V converter circuit 6a and the level is equal to the level of the signal. Therefore, the introduced noise signals are offset when the output of the circuit 13 and the output of the circuit 6a are added. The phase information when the body X is not present becomes random, and the phase does not gradually approach the phase of the introduced noise signal. Therefore the erroneous measurement of a distance can be prevented. Furthermore, the erroneous operation due to the increase in phase noises when the received light signal is decreased can be prevented.

Filed: 1986-10-20
Abstract: PURPOSE:To make it possible to clean efficiently by arranging a cover in a shape that prevents ultrasonic waves generated coherently from interfering with ultrasonic waves reflected with the cover, even if such a reflection occurs. CONSTITUTION:An ultrasonic vibration element 3 is attached at the widest part 7a of a truncated cone cover 7, with an object to be cleaned arranged facing a liquid jet port 7b of an ultrasonic pump 8.
