A CRT focus correcting method and correcting circuit are arranged as follows. Size data of a picture size set externally are compared with size data of a reference picture size, and when it is detected that a picture size has been changed, calculation correction data are obtained based on reference correction data and both the size data. When a parabola waveform voltage based on the calculation correction data is applied to a focus coil, a CRT focus is corrected according to a change in the picture size.

An apparatus for driving an expansion pole such as an expansion corner rod of an automobile including a motor for extending and shrinking said expansion pole, a main switch provided within a room of the automobile, and an auxiliary switch provided on the automobile at such a position that the auxiliary switch can be actuated from an outside of the automobile. When the auxiliary switch is actuated from the outside of the automobile, the motor is driven in a reverse direction to shrink the expansion pole. Therefore, the expansion pole can be shrunk without actuating the main switch provided within the room of the automobile. The auxiliary switch may be arranged within the expansion pole such that the auxiliary switch is actuated when the expansion pole is pushed down, pulled up or tilted.

In a disclosed PLL circuit, a constant voltage output by a constant voltage power supply 6 for obtaining a signal with a frequency equivalent to that obtained in a synchronized state is added to a signal output by a filter 3 by means of an adder 7. A signal output by the adder 7 representing the sum of the voltage output by the constant-voltage power supply and the signal output by the filter is supplied to a voltage-controlled oscillator 4. With a reference signal Pi supplied, the PLL circuit functions like an ordinary PLL circuit. When the signal Pi becomes unavailable, however, a signal output by a reference-signal-input detecting circuit 5 for monitoring the reference signal Pi puts integrating components employed by the filter 3 in a short-circuit state, initializing information accumulated in the integrating components. In addition, the output of the filter is set to zero. In this state, only the constant voltage output by the constant-voltage power supply 6 is therefore supplied to the voltage-controlled oscillator 4.

This invention provides a paper molded cushion having a sufficient shock absorbing ability without substantial deformation during the drying process even if the shape of the cushion is very complex. The process comprises the steps of mechanically fluffing waste paper or pulp, adding a proper amount of adhesive to the fluffed paper of pulp, mixing uniformly, casting the mixture in a mold having water drainage small apertures thereof, heating said mold with the mixture therein by dielectric heating or microwave heating, thereby drying the molded paper cushion to a predetermined water content level and taking out the molded paper cushion from the mold. It is also possible to heat and dry the molded paper product under reduced pressure conditions for accelerating the water evaporation or to add a small amount of foamable synthetic plastic particles with the adhesive for making voids inside the molded paper cushion; consequently, the weight of the paper cushion is effectively reduced and the shock absorbing ability is increased. Further if the shape of the product is complex, the mold is divided into plurality of cross-sectional layer parts corresponding to the cross-section of the desired shape and the molded paper parts are assembled with adhesives to form the final shape of the paper cushion.

A soybean processing system separates whole soybeans into cotyledons and hulls, and separates the cotyledons into two outlets. The cotyledons from one of the outlets are processed into a deodorized soybean powder, whereas the cotyledons from the other outlet are processed into a nondeodorized soybean powder. Therefore, two types of soybean powder are produced by the single system. The protein contained in the deodorized soybean powder is coagulated into a soybean curd which is formed to a certain shape.

A method for synthesizing trioxane by heating and reacting an aqueous formaldehyde solution in the presence of a heteropolyacid. As the heteropolyacid, there is preferably used one that contains, as a coordinating element or coordinating elements, W, Mo, V or Nb alone or two or more of them.
摘要:
A magnetic recording medium having excellent magnetic properties and a uniform recording envelope suitable for, in particular, high-density recording is obtained by packing a magnetic substance in the micro pores of anodic oxide film formed on an aluminum substrate by subjecting the same to an anodic oxidation treatment to produce an anodic oxide film having a thickness of at least 4 .mu.m. The recording medium can be improved by immersing the anodized aluminum substrate in an acid or alkali bath to chemically dissolve a part of the anodic oxide film, and thereby enlarge the micro pores in the anodic oxide film to a pore diameter in the range of 300 .ANG. to 1,400 .ANG., optionally applying an electric current to the aluminum substrate in the immersion bath if necessary to control the thickness of the barrier layer in the anodic oxide film, before subjecting the treated substrate to an electrolytic treatment in a bath containing ions of a magnetic substance to deposit the magnetic substance in the enlarged micro pores. Thereafter, the surface of the anodic oxide film, and any excess deposited magnetic material thereon, is physically ground to expose the packed magnetic substance at the surface of the film.

In a process for separating trioxane by a continuous distillation which comprises extracting, with benzene, the trioxane-containing distillate obtainable by heating an aqueous solution of formaldehyde, feeding the trioxane-containing benzene solution into a distillation column as a starting material, distilling out the benzene from the column top and withdrawing the trioxane from the column bottom, a process for separating trioxane which comprises retaining the concentration of trioxane X in the liquid composition at the starting material feeding plate of the distillation column (% by weight of trioxane based on the total liquid composition at the feeding plate) in the range satisfying the following relationship: ##EQU1## wherein R is reflux ratio, and .gamma. is a parameter defined by the following equation: ##EQU2## wherein q is the proportion of liquid part in the fed starting material as expressed in terms of ratio by weight and C (%) is the concentration of trioxane in the fed starting material.
摘要:
A pharmaceutical preparation of oral cavity administration, characterized by being a mixture of a pharmacologically active agent, a pharmaceutical carrier, and sodium polyacrylate, in conventional dosage form. It has advantages in that it adheres strongly to local site and dissolves gradually over a prolonged period of time while releasing appropriate amounts of the active agent.

A handler includes a device holding portion, which holds an uninspected device and loads the device in a measuring socket on a device tester, having a suction means for sucking the device by a very weak pushing force at the time of sucking the device from an uninspection tray and for loading the device in a measuring socket and also having a clamper capable of outputting a pushing force which can be changed at the time of the measurement contact. The device holding portion includes a position correcting mechanism for making a device position correction executed by an image recognizing and position correcting means.
