Title: Bar-shaped iron core
Inventor: SASAKI NAOKI
IPC: H01F38/12
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To make a bar-shaped iron core easily manufacturable and the length and thickness of the core easily adjustable, by forming a conical tapering-off section by winding a belt-like metallic sheet having a slope formed to gradually reduce the width of the sheet in the longitudinal direction by using the broader width-side end of the sheet as a winding starting end. SOLUTION: The width of a belt-like metallic sheet 1 having a prescribed width and length is gradually reduced from one end side to the other end side by forming a slope 2 by cutting the sheet 1 in the longitudinal direction. When the sheet 1 is wound by using the broader width-side end A as a winding starting end, an iron core 3 having a conical tapering-off section 2a which gradually becomes thinner toward the front end from the base section 2b can be formed. A high-voltage generating coil is constituted of primary and secondary windings wound around a bobbin 4 by using this core 3. The core 3 is inserted into the bobbin 4 with the thicker base section 2b on the low-potential side of the secondary winding 6 and the thinner front end section 2a on the high-potential side of the winding 6. Consequently, the insulating distances between the bar-shaped iron core 3 and windings can be secured without reducing the number of the windings or changing the wall thickness of the bobbin 4 as the potential at the windings become higher.

CONSTITUTION:A local oscillating circuit 4A is constituted by providing a multiplier circuit 30 comprising a distortion generator 31, a BPF32 and an amplifier 33 between a VCO11 and a variable frequency divider 12. Further, a reference comparison frequency of a reference oscillator 13 is set to the outside of a signal transmission band, e.g., 1,000kHz in case of the MF broadcast reception. The relation of fv=NTXfR is obtained, where fv is the oscillating frequency of the VCO11 in the circuit 4A, NT is the total frequency dividing number of the PLL and fR is the reference comparison frequency of the oscillator 13, and the relation of fv=fRXN/M is obtained, where N is the number of frequency division of the variable frequency divider 12 and M is the number of multiple of the circuit 30. Thus, the oscillating frequency fv of the VCO11 is other than an integral number of multiples of the frequency fR, the reception and channel selection at the step below the frequency fR is made possible, and since this step is decidec substantially by fR/M, the channel selection is atained at the step of 50kHz each with the M of 2.

Title: Plate spring with crowing for hard disk drive
Inventor: YAMAOKA KEISUKE
IPC: G11B21/02
Filed: 1986-09-19
Abstract: PURPOSE:To prevent the rupture of a steel belt and to hold a plate spring and the steel belt in the same contacting condition by having a crowning at a part to wind the plate spring and the steel belt. CONSTITUTION:At a part to wind a steel belt 2 of a plate spring 1, a crowing 11 is formed. For this reason, even when a fine dislocation is present in the fitting direction of the plate spring 1 and in the pulling-out direction of a steel belt 2, a scope (a) of a part to contact with the plate spring 1 of the steel belt 2 comes to be larger. As the result, a large load is not concentrated to extremely a part of the steel belt 2, and consequently, the rupture of the steel belt 2 due to the concentration load can be prevented. By having the crowning 11 at the plate spring 1, the assembling accuracy of the steel belt 2 is deteriorated in a fine quantity and then, the plate 1 and the steel belt 2 can be held in the same contacting condition.

Title: Image sensing apparatus
Inventor: HASHIMOTO SEIJI
IPC: H04N5/335
Filed: 1986-09-19
Abstract: PURPOSE:To enhance photometric accuracy while picking up an image at a high speed, by collectively adding a plurality of sensor signals to calculate reading photometric information and dispensing with reading action and operation at each of pixels. CONSTITUTION:An image is picked up by an image sensing element 1 in such a state that an exposure control apparatus 11 is opened. Continuously, the addition value Sae of each line is read in a non-destructive manner at a preset clock speed (f) and subjected to integral processing by an integration circuit 5 to compare photometric information V1 with set values V2, V3 (V2<V3). As a result, at the time of V1<V2, a system controller 9 controls a clock circuit 4 to delay the clock speed (f) when the addition valve Sae is read to raise the addition value Sae and, at the time of V1>V3, the clock signal (f) is made fast to lower the Sae. By this action, when V2<=V1<=V3 is formed, the system controller 9 controls the apparatus 11 on the basis of the photometric information V1 and the clock speed (f) as reference at that time to determine the exposure. Then, the image is again sensed by the element 1 to be outputted to an output signal circuit 12.
