IPC: G11B21/08
Filed: 1985-03-29
Abstract: PURPOSE:To accurately detect the movement amount of a pickup by counting the number of times of the pickup traverses a track when the pickup is moved at a fast speed radially of a disk, by counting the number of revolutions of the disk, and adding or subtracting the count values depending on the moving direction of the pickup. CONSTITUTION:The signals of a prescribed period synchronized with the rotation of the disk 11 is supplied to a pulse generating circuit 31, turned into signal (c), the signals (d) at a rate of one pulse per disk rotation is produced and supplied together with the output of the counter 18 to an adder/subtractor 33. The switching between the addition and subtraction is by the signals indicating the feed direction of the pickup 13 supplied from a feed motor control circuit 15. By such construction, the number of rotation of the disk 11 and the number of times the pickup 13 traverses the track are counted and the movement amount of the pickup 13 can be correctly detected by a simple construction.

Abstract: PROBLEM TO BE SOLVED: To facilitate pavement work of a permeable road by bulging an appropriate place of the outer surface of one side wall to form a projecting part in order to form a stepped part at one side wall forming a side ditch channel formed by both side walls. SOLUTION: A side ditch channel 3 is formed by both side walls 11, 11 and a bottom plate part 12, and in order to form a stepped part 9, an appropriate place of the outer surface of one side wall 11 is bulged to form a projecting part 5. A drainage culvert 1 is laid at a side part of the ground to construct a permeable road on so as to obtain a preset position where the upper face of asphalt pavement is flush with the upper end face of the projecting part 5 formed at the drainage culvert 1. A worker then forms asphalt pavement with the upper end face 51 of the projecting part 5 as a standard. Permeable pavement is then formed on the asphalt pavement up to the stepped part 9 of the side wall 11 of one drainage culvert 1 with preset height. Pavement work of the permeable road can therefore be facilitated.

Abstract: PROBLEM TO BE SOLVED: To make it possible to simplify the element structure and to realize a high-speed modulation by providing one end face of a substrate with an antireflection film and providing the other end face of the substrate with a total reflection film. SOLUTION: The optical modulator 1 constitutes an optical waveguide 6 from a first clad layer 3 formed on a substrate 2, striped optical modulation layers 4 formed thereon and a second clad layer 5 formed thereon. The light (incident light) sent from outside toward the optical modulator 1 is introduced from the end face on which an antireflection film 10 is applied to the waveguide 6. The light propagates successively in the waveguide 6, reflects totally at the end face on which a total reflection film 11 is applied, propagates again in the waveguide 6 and is emitted from the end face applied with the antireflection film 10. The intensity distribution in the waveguide direction of the light of this time changes with an increase in the voltage impressed by a first electrode 8 and a second electrode 8.  In such a case, the operating voltage is decreased by prolonging the element length of the optical modulator 1 and a twice higher extinction ratio is obtd. with the same voltage.

Abstract: PURPOSE:To connect directly an input circuit to an already provided power amplifier no matter whether the output type of the already provided power amplifier is BTL or unbalance, by setting resistances, which are connected between input terminals of a differential amplifier and between input terminals and the earth, to certain values. CONSTITUTION:An input circuit 1 is provided with a differential input amplifier A1, resistances R1 and R3 constituting an attenuator for its non-inverted input (+side), resistances R2 and R4 constituting an attenuator for its inverted input (-side), and a feedback resistance R5 which determines the gain, and the input circuit 1 has one output terminal, and this terminal is the non-inverted input of a power amplifier A2. In this input circuit 1, respective resistance values are set to satisfy R1=R2, R3=R4.R5/(R4+R5), and R2>R4. The gain viewed from the non-inverted input terminal of the differential amplifier A1 is determined by (R4+R5)/R4, and the influence of the impedance connected between an input terminal I2 and the earth can be ignored. Thus, it does not matter wheter the output type of the already provided power amplifier connected between input terminals I1 and I2 is unbalance or BTL.

Title: Power system, discharge lamp lighting device, and lighting system
Inventor: KOSA KIYOTERU
IPC: H02M7/12
Filed: 1994-03-31
Abstract: PURPOSE:To prevent the abnormal operation at the time when the power is turned on by inhibiting an inverter from starting until a specified period of time is measured by a timer after a step-up chopper is started up in the equipment wherein the self-excited inverter circuit is connected to the output side of the step up chopper circuit. CONSTITUTION:When a commercial ac supply E is turned on, a capacitor C13 of a step-up chopper circuit 23 is charged and a transistor Q15 comes to an on-state. Therefore, even if a capacitor C14 is charged and then a trigger device Q14 gets turned on, the gate voltage is not applied to a field effect transistor Q13 of an inverter circuit 25 and thereby the inverter circuit 25 does not oscillate. After that, when the capacitor C13 is charged and the step-up chopper circuit 23 starts operation, voltage is induced in a coil L12. When capacitors C17, C18 are fully charged, a Zener diode ZD1 comes to a reverse-blocking state and voltage is applied to the gate of the Q13 and then the inverter circuit 25 oscillates and thereby a fluorescent lamp FL light.
