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.
摘要:
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.

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 spark plug is disclosed as having a metal shell, a porcelain insulator fixedly secured to the metal shell, a center electrode and a ground electrode providing a spark discharge gap with the center electrode. The porcelain insulator has a through-bore partially exposed from an end face of the ground electrode in a surface area S1, as viewed from a distal end of the spark plug, and having a total surface area S2 falling in the relationship S1/S2≦0.3. The center electrode protrudes from the porcelain insulator with a protruding length L under the relationship L≦0.6 mm. A minimal value Hmin and a maximal value Hmax in distance between the ground electrode and the end face of the porcelain insulator lies in the relationship Hmax/Hmin≦1.3. Wall thickness T between the through-bore and an outer periphery of the porcelain insulator lies in the relationship T≦0.7 mm.
