Title: Improvements to or relating to cathode ray pick-up tubes or the like
Inventor: LALLEMAND ANDRE
IPC: H01J31/32
Filed: 1953-01-06
Abstract: 736,987. Television pick-up tubes. L'OUTILLAGE, R. B. V. Jan. 6, 1953 [Jan. 8, 1952], No. 390/53. Class 39 (1). In a pick-up or like tube with a plane photocathode spaced from a curved storage target, the photo-cathode and scanning gun both face the concave side of the target, the photoelectrons are focused and accelerated by an electron lens and the centre of deflection of the scanning beam coincides with the centre of curvature of the target. In a low velocity beam scanning arrangement the optical image is projected on to photo-cathode 4 and the resulting electron image focused and accelerated by immersion lens 20, 21, 22 sets up a charge image on target 5 which is scanned by the low velocity beam from gun 10, 11, 12. The output can be taken from signal plate 7 or by passing the returning electrons to a multistage multiplier 27. Target 5 is shaped as a spherical cap and may be of glass which charges by secondary emission or of electron bombardment induced conductivity material such as CdS. Second anode 13 is a wall coating interrupted near the target 5 to form two or more ring electrodes 17, 18, 19 at decreasing positive potentials to decelerate the beam and ensure its normal approach to the target. Electron lens 20, 21, 22, electrode 22 which is connected to wall coating 13 and has diaphragm 30 at the cross-over point, is designed to correct the field curvature to compensate for the fact that the optical image and photo-cathode are plane while target 5 is curved. The construction of rings 17-19 is such as to minimize interaction between the two sections of the tube. If a high velocity scanning beam is used, interaction minimizing design is unnecessary and rings 17-19 may be omitted or kept at the potential of second anode 13.

Apparatus for micro-finishing peripherally extending grooves 11 of arcuate profile in the internal or external periphery of cylindrical workpieces, such as ball races, comprises a honing stone 12 which engages the arcuate groove and performs a swinging movement about the centre of curvature of the arc of the groove, a rotatable disc 2 for frictionally rotating the workpiece, a stationary shoe 3 against which the periphery of the workpiece abuts, and a rotatable abutment 4 concentric with the axis of the workpiece and axially displaceable, the axes of the workpiece and abutment being parallel to a radius of the disc 2 so that the disc produces a component which urges the workpiece against the rotatable abutment. The driving disc is rotated by a pulley drive 24 and frictionally engages the workpiece which abuts the stationary shoe 3 and is pressed against the disc and shoe by a piston-pressed roller 7. The abutment 4 is axially displaceable by a piston 6 and carried by a, frame 25 on a shaft 27 and the abutment, after the honing stone engages the groove, is moved a small distance so as not to prevent the workpiece adapting itself to the stone. The honing stone 12 is mounted on a lever 13 pivotally connected to a sleeve 20 oscillatable by a crank drive 18, 19 to rock the stone about the centre of the arc of the groove, and the lever 13 is connected by a link 14 to a rod 15 axially displaceable by a piston 16 to retract the stone from the workpiece. As described, the apparatus has nine stations; at the first three a preliminary honing is effected, at the second three a finish honing is effected, and the last three comprise loading and unloading stations. Each station has a rotatable abutment 4, shoe 3 and pressure roller 7 carried by the frame 25 which is supported by a shaft 27 indexable by a worm drive 31 to positions spaced apart 120 degrees and determined by a pistonoperated detent 34 to move the elements. Each station in the first and second groups has an oscillating sleeve unit 20 with a honing stone, one station of each group being oscillated by the crank drive 18, 19 and imparting oscillation to the other stations of its group through toothed belts on pulleys 21a. In order to permÝt indexing of the workpieces from station to station, the honing stones are retracted from the workpieces by moving piston 16 to a position engaging a retractable stop 41 so that the stones first move to positions B, Fig. 4, from their operative positions A, the supports for the crank mechanisms 18 are then moved so that the stones rock to the positions C, and the stops 41 are then retracted by moving pistons 42 so that the stones are further retracted to the positions D. In other embodiments, the shoes 3 and abutments 4 are modified to permit honing of the external grooves of inner races.

Title: Low power consumption electronic circuit
Inventor: YAMASHIRO OSAMU
IPC: H02M3/07
Filed: 1986-06-19
Abstract: According to the present invention, the voltage of a battery is supplied to an electronic circuit such as a watch circuit through a step down circuit which is constructed of capacitors and switching MIDFETs. The step down circuit performs a current converting operation as well as a voltage converting operation. The operating current of the electronic circuit is reduced by the reduction in the operating voltage of the same. As a result that the operating current level of the electronic circuit is dropped and that the current conversion is performed by the step down circuit, the battery current is relatively largely dropped. The construction thus far described elongates the lifetime of the battery. According to the present invention, therefore, there is provided a circuit which is proper for driving the step down circuit.
