A heater is inserted into an inside chamber of a sensor element until a tip end of the heater is surely brought into contact with a bottom surface of the inside chamber. Next, a metallic holder is attached on an outside surface of the heater. Then, the metallic holder is slid along the outside surface of the heater toward the bottom surface of the sensor element to engage the metallic holder with an edge of the sensor element.

When a developing agent prepared to have a preset toner density is loaded in a developing unit, a comparing reference level for controlling the toner density in the developing agent is changed to a value higher than the preset value in the initial stage of operation and fresh toner is supplied to the developing agent so that the toner density of the developing agent is increased in comparison to the reference level. Thereby, the developed density is prevented from decreasing due to an excess amount of friction charge of the toner.

A magneto-optic recording system uses a unit recording medium having on a substrate a first magnetic layer whose Curie temperature is low and also having on the first magnetic layer a second magnetic layer whose Curie temperature is high. The system heats a spot on the medium with a heating device. The system may employ two such unit recording media, each having the second magnetic layer magnetized in one direction. The two unit recording media are superposed on each other and formed integrally so as to obtain a magneto-optic recording medium in which the amount of information recorded and the recording speed are doubled. In addition, a light-emitting device and a magnetic field generator are added to the magneto-optic recording medium to obtain a compact magneto-optic recording system with a low level of power consumption.

A unit recording medium, having on a substrate a first magnetic layer whose Curie temperature is low and also having on the first magnetic layer a second magnetic layer whose Curie temperature is high, is heated by a heating device. After two such unit recording media each having the second magnetic layer magnetized in one direction are fabricated, and the fabricated two unit recording media are superposed on each other and formed integrally so as to obtain a magneto-optic recording recording medium in which the amount of information recorded and the recording speed are doubled. In addition, a light-emitting device and a magnetic field generator are added to the magneto-optic recording medium to obtain a compact magneto-optic recording system with a low level of power consumption.

An avalanche photodiode includes a multiplication layer and a photoabsorption layer, and the multiplication layer is formed of a semiconductor superlattice structure composed of a number of well layers each of which is formed of a short period superlattice of at least two kinds of semiconductors and which can be equivalently regarded to be a mixed crystal of the at least two kinds of semiconductors. In the short period superlattice, the mini-bands are formed within the superlattice well layers having its effective forbidden band width, which is larger than the forbidden band width in a bulk condition of a semiconductor layer constituting a well in the short period superlattice. Thus, the dark current due to the inter-band tunnel transition within the same well layer is decreased. Therefore, a low noise characteristics and a low noise and high response speed characteristics obtained by a high ionization rate ration can be simultaneously realized.

In an optical disk apparatus for recording information in pits formed on an optical disk by projecting a light beam onto the optical disk and heating an area of the optical disk corresponding to the pulse pattern of the information, the pulse pattern of the information to be recorded is discriminated, and on the basis of the discriminated pulse pattern, the timing to start on and end the emission of the light beam from the light source to the optical disk is modified, or the number of emissions and the duration of each emission is controlled so that the pattern of the pits are corrected to the shapes that ensure accurate regeneration of the information.

A magneto-optic recording medium has a cartridge provided with a magnetization direction indicating portion for indicating the direction of magnetization of a second magnetic layer. Alternatively, the direction of magnetization of the second magnetic layer is recorded in advance in the first magnetic layer. The direction of magnetization of the second magnetic layer indicated or recorded is detected and recognized. A magnetic field oriented in an opposite direction to the direction of magnetization detected is imparted to the magneto-optic recording medium. Alternatively, predetermined information is recorded in the first magnetic layer, the direction of magnetization of the second magnetic layer is detected on the basis of a signal reproducing that information, and the direction of a magnetic field to be applied to the magneto-optic recording medium is set on the basis of the direction of magnetization thus detected. In addition, the direction of the magnetic field to be applied to the magneto-optic recording medium is set and the output of a light beam is changed on the basis of the direction of the second magnetic layer detected.

Dry process for the production of inorganic granular substances coated with plastics, characterized in that a radical-polymerizable vinylic monomer carried on the surface of an inorganic granular substance is brought in a gaseous phase into contact with gaseous sulfur dioxide to effect polymerization of the monomer. The resulting plastic-coated inorganic substances are useful in various fields of industry, for example, as fillers, construction materials, molding materials, electrode materials, delayed-action fertilizers, etc.

In a wristbhaving a label-like structure, fracturing notches for preventing unauthorized use are positioned where the two ends of the band are to be glued together. If temporary peeling of the glued ends is attempted, the wristband breaks reliably and it is difficult to return it to the original state. If fracturing notches (11) are formed on either a first winding region (6) or a second winding region (7), which are positioned at left and right ends of the printing region (5). The wristband is configured so that a ring shape can be formed by overlapping and adhering the adhesive layer on the rear surface of one of shape, the first winding region (6) or the second winding region (7) onto the other winding region. An adhesion position check mark (15, 16) is formed on either the first winding region (6) or the second winding region (7).
