Title: Phase synchronizing oscillation circuit
Inventor: TANABE YOSHIAKI
IPC: H03L7/14
Filed: 1981-02-24
Abstract: PURPOSE:To obtain a phase synchronizing oscillation circuit with less acquisition time, by controlling and starting a voltage-controlled oscillator with a stored control voltage, when an input signal is interrupted and restored afterward. CONSTITUTION:A voltage controlling line controlling a voltage-controlled oscillator 12 is provided with an integrator 21 outputted to two directions and a switching device 20, and if an input signal is given to a terminal 11 normally, the output of the integrator 21 is given to an integrator 23 via a switch 22 and the integrator 23 holds a control voltage. When the input signal is interrupted, the switch 22 disconnects the connection between the integrators 21 and 23 with a signal detecting circuit 17, the switcher 20 outputs the control voltage stored in the integrator 23 to control the oscillator 12 for synchronizing oscillation. A switching device 18 outputs the control voltage stored in the integrator 23 and the integrator 21 stores it. When an input signal is restored, the switching device 20 gives the control voltage stored in the integrator 21 with the circuit 17 to the oscillator 12 for the start of synchronizing oscillation. Thus, the amount of shift of the oscillation frequency is further decreased and the acquisition time can stably be shortened.

Filed: 1989-02-03
Abstract: PURPOSE:To realize the long life of an ion beam distribution measurement device by providing the device with a metal mesh having the thickness sufficiently endurable of incident ion spattering in place of a charging-up prevention metal film. CONSTITUTION:When a measurement ion beam 5 is irradiated on an ion beam distribution measurement device, an ion 7 passes a gap of a metal mesh 3 to directly reach a phosphor layer 2 so as to emit phosphor. At this time, part of the ion 8 is blocked by the mesh 3 which is sufficiently thicker than a project range not to reach the layer 2, but it is no problematic that an ion beam distribution is measured if the mesh pitch is sufficiently small. Secondary electrons 9 generated from the surface of the ion beam distribution device are controlled by applying negative voltage at the mesh 3 by a power source 4 to release positive charge electrified on the surface thereof so as to prevent charging-up. Thereby, damage of the device can be reduced and long life can be contrived even if the surface of the ion beam measurement device is exposed in spattering by the ion.

Title: Gel type volatile drug
Inventor: OI SATORU
IPC: A01N53/00
Filed: 1989-02-07
Abstract: PURPOSE:To obtain the subject drug capable of stably and sustainedly releasing a drug gel containing a drug volatile at ordinary temperature by filling the drug gel in an inner container provided with a nonwoven fabric in one side part thereof and housing the inner container in a state in which the surface of the nonwoven fabric is placed downward or tilted obliquely downward in an outer container having through- hole parts. CONSTITUTION:The subject drug obtained by filling a drug gel (G) containing a drug volatile at ordinary temperature in an inner container 1 so as to bring the above- mentioned gel (G) into contact with a nonwoven fabric 2 covering an opening of the inner container and housing the inner container 1 in an outer container 3 having through-hole parts 4 so that the surface of the nonwoven fabric 2 may be tilted downward or obliquely downward. Although the volume of the drug gel (G) is reduced with time by volatilization of the drug, the gel is always in a state of contact with the nonwoven fabric by own weight thereof. Thereby, the solvent in the gel and volatile drug are exuded and impregnated into the nonwoven fabric to volatilize the drug using the surface of the nonwoven fabric as a volatile surface having a wide volatilizing surface with high efficiency. Since the volatile drug is stably and sustainedly volatilized for a prescribed period without forming any residue, the drug has advantages in that the end point can be definitely discriminated.

Abstract: PURPOSE:To enable the easy formation of the ridge type optical waveguide which has excellent reproducibility and film thickness uniformity and is not deteriorated at all in thin film crystallinity by using a flux heated to a saturation temp. or above as an etching liquid. CONSTITUTION:A thin-film part 2 which constitutes the optical waveguide is formed on the upper part of a substrate 1 and a mask pattern of the optical waveguide shape is formed by using a general photolithography technique thereon. The thin-film part is then etched in the melt of the flux heated to the saturation temp. or above by using the flux as the etching liquid. The etching in the melt is not isotropic etching and does not generate undercuts. In addition, the reproducibility of the etching speed is excellent and the nonuniformity in the etching speed as well ion beam etching and reactive ion etching does not arise and, therefore, the film thickness uniformity is excellent and the thin film crystallinity is not deteriorated at all. The ridge type optical waveguide having the excellent optical characteristics are, therefore, extremely easily formed.
