Inventor: MARUSERU HIYUUREN
IPC: H04N7/00
Filed: 1991-06-06
Abstract: PURPOSE: To provide a letter box extended TV system where an additional signal does not interfere in the synchronizing circuit of a picture receiver by generating an edge part picture signal in the horizontal, which has not any low frequency component in the horizontal direction, at the time of encoding an additional information signal. CONSTITUTION: An analog input signal is multiplied by a prescribed factor in a multiplier 43, and this signal passes a BFP 45 to subtract the band width of a portion of a transmission power (for example, 500kHz) to be removed from a subcarrier frequency. Next, an U(I) or V(Q) subcarrier is modulated by this signal in a modulator 47. Thereafter, the signal is multiplied by +1 or -1 in line sequence in accordance with a function for each line or field. The polarity sign is switched by providing a multiplier 49 in an arbitrary position before addition of an offset in an adder 53. The output signal of the multiplier 49 is subjected to a Nyquist filter processing by a means 51, thus obtaining the edge part signal in the horizontal direction which is so encoded that it may be combined with a picture signal of a wide picture to form a signal of a standard aspect ratio.

Title: Laser beam machine
Inventor: NAKADA YOSHINORI
IPC: B23K26/00
Filed: 1992-06-19
Abstract: PURPOSE:To irradiate a workpiece with a laser beam and to stably and uniform ly perform cutting. CONSTITUTION:The kerf width L of a workpiece 5 is detected by a monitor 4 for a kerf width, and the detected data is sent to a means 11 for discriminating groove width in a control device 10. By the means 11 for discriminating groove width, the kerf width L is discriminated whether or not it is within a prescribed width, and the result discriminated is sent to a means 12 for controlling the width of a cut groove. By this means 12, when the kerf width L is not within the prescribed width, the cutting conditions are changed so as to fit the kerf width L within the prescribed width, and the kerf width L is controlled. That is, even when the kerf width L is out of the prescribed width by the influence of the converging performance, etc., of the laser beam B, the cutting conditions are changed, and the influence of the converging performance, etc., may be removed. Consequently, the width of a cut groove is always kept specified, and the working quality is made uniform. Thus, a stable and uniform cutting is performed.

Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To simplify the production process and to reduce the size of apparatus constitution and the cost of a polarizing element by making the sum of the thicknesses of first kind and second kind double refractive materials forming the unit period of a unidirectional periodic structure sufficiently smaller than the wavelength of incident light. SOLUTION: This polarizing element has the unidirectional periodic structure which consists of the double refractive materials A, B of the same kind and in which the first kind double refractive materials A and second kind double refractive materials B which are different in alignment directions are alternately repeated. The element is so set that the sum of the thicknesses of the first kind double refractive material A and the second kind double refractive material B forming the unit period of the unidirectional periodic structure is sufficiently smaller than the wavelength of the incident light. The incident M polarized light is converted to L polarized light in the same manner as heretofore by controlling the refractive index in the M-axis direction by only the double refractive materials A, B of one kind.  This L polarized light is transmitted while the same polarization state as that at the incident time is maintained. As a result, the unidirectional periodic structure capable of developing the conversion function to convert all of the light transmitted through the polarizing element to the L polarized light without loss is embodied.

Title: Electronic device
Inventor: SHIMIZU HISAYOSHI
IPC: G06F1/00
Filed: 1985-07-24
Abstract: PURPOSE:To attain sure power-on reset with simple circuit constitution by applying a power voltage to a capacitor via a resistive element and a constant voltage element so as to inhibit the charging to the capacitor until the constant voltage element is brought into the operating state. CONSTITUTION:A power voltage VCC is fed to the capacitor C via a resistor R1 and a Zener diode ZD. A 1-chip microcomputer starts reset operation at a time T1 when the power voltage VCC reaches a lower limit operating voltage of a semiconductor integrated circuit device. Since the Zener diode ZD is turned on, the charging of the capacitor C is started. A transistor (TR) Q1 is switched from the off to the on-state at a time T2 when the charging voltage Vcr reaches the threshold voltage Vth of the TR Q1. That is, even when the leading of the power voltage VCC is slow, the reset period at least from the time T1 to the time T2 is ensured. Thus, sure power-on reset is guaranteed.

Title: Deflection yoke device for projection television
Inventor: SEKI TAKESHI
IPC: H04N5/74
Filed: 1994-07-14
Abstract: PURPOSE:To improve connection of a deflection yoke main body and the lead wires by using the connector housings. CONSTITUTION:The connector housings CH 10a-10c are connected to both ends of each of short (30cm) lead wires A1, A2, C1 and C2 and also connected to one of both ends of long (1m) lead wires B1, B2, D1 and D2 together with a connector housing CH 9 connected to the other end of the long lead wires B1-D2 respectively. Thus only four long lead wires are needed and all other lead wires have short lengths so that the total cost of lead wires can be reduced. Furthermore the lead wires can be separated from the connector housings when a deflecting yoke main body is assembled owing to these connector housings used for connection between the lead wires and the deflecting yoke main body. Thus the assembly efficiency is improved for a deflection yoke device. In addition, just a single post suffices at the side of a TV set and therefore the substrate area of the TV set can be reduced together with improved connection.
