An oscillation driver circuit includes a gain control amplifier which causes a vibrator to produce driving vibrations by controlling an oscillation amplitude in an oscillation loop, and a comparator which generates a synchronous detection reference signal based on a signal in the oscillation loop. The comparator has an output current limiting function. The oscillation driver circuit causes the vibrator to produce vibrations using an output from the comparator in a state in which the gain in an oscillation loop formed by the vibrator and the comparator is set to be larger than unity, and then causes the vibrator to produce the driving vibrations by controlling an oscillation amplitude in an oscillation loop formed by the vibrator and the gain control amplifier.

In the manufacture of a physical quantity detector, such as a pressure sensor and a load sensor, comprising a cylindrical part of which one end is closed with a strain generating part and a sensor part formed on the strain generating part, the cylindrical part mentioned above is produced by melting an alloying material having a composition capable of yielding an amorphous alloy, injecting the resultant molten alloy into a metal mold, and cooling the molten alloy in the metal mold to confer amorphousness on the alloy. The metal mold is composed of a split mold having at least two split parts for forming a cavity and an insert pin to be inserted into the cavity so as to define the inner configuration of the cylindrical part, or further an insert core to be inserted into the mold so as to form the surface of the cavity corresponding to the surface of the strain generating part. In another embodiment, the cavity is formed so that the parting face of the mold corresponds to the surface of the strain generating part.

The printing apparatus comprises a first detachable unit U1, a second detachable unit U2, and a main body unit U5 formed such that the first and second detachable units U1 and U2 are detachably mounted thereto. When a unit fixing means 33 provided on a head unit U3 of the main body unit rotates in a clockwise direction to be laid horizontally and then a boss 36 is fitted into a concave portion 33A, the head unit U3 and a pinch roller unit U4 are connected to each other through the unit fixing means. The first detachable unit is pressed by a left end of the unit fixing means, and the second detachable unit is pressed by a right end of the unit fixing means. As a result, it is possible to prevent the first and second detachable units from separating from the main body unit forward. In addition, when the unit fixing means is rotated in a counterclockwise direction to be upwardly constructed, the first detachable unit U1 and the second detachable unit U2 can be mounted detachably to the main body unit.

An image with sufficient gray-scale representation and high resolution is formed on a medium to be recorded, such as an intermediate transfer body, using a thermal printer employing thermal transfer ink. When thermal transfer ink of a thermal transfer ink ribbon 18 is thermally transferred onto an intermediate transfer body 12 by a thermal head 14, gray-scale values of pixels of a filter image having a threshold value pattern used to determine whether each of a plurality of pixels of an original image is an object to be printed, based on gray-scale values of the pixels, are compared with the gray-scale values of the pixels of the original image, and then the gray-scale values of the pixels of the original image are converted based on the result of the comparison. A gray-scale conversion table in which energy applied to the pixels at the time of printing is prescribed corresponding to the gray-scale values of the pixels is compared with the converted gray-scale values of the pixels of the original image, and the converted gray-scale values of the pixels of the original image are further converted on the basis of the result of the comparison. In addition, the application of a current to the thermal head 14 is controlled according to the converted gray-scale values of the pixels of the original image.
