An image printing method and system. Information of printing paper size, image size to be printed and printing position is inputted by user. On the basis of the information, a control circuit determines the number of data to be printed in the primary scanning direction as well as the number of data for blanks at both sides and additionally determines the number of lines for printing in the secondary scanning direction as well as line numbers for processing and succeeding blanks. In the primary scanning, the data to be printed is supplied to a thermal head together with the data for the blanks. In the secondary scanning, a printing sheet is transported idly for the blank portions. The thermal head is electrically energized in the printing portion for printing the image at a predetermined position on the printing paper.

In order to perform selective sound reproduction from a plurality of recorded grooves on a record disc, a stopper block for stopping a record disc at a position where starting point of the record disc is able to engage the reproduction stylus of a pickup is disposed on the reverse side of the record disc. A plurality of locking bars corresponding to the number of recorded grooves are distributed along a circle concentric with the record disc and the circle has a radius smaller than the radius of the record disc.The locking bars are urged by a flat spring having radial teeth fixed around a shaft holder for receiving the center shaft toward direction, and are normally held by the spring apart from the stopper block. The center shaft as a center of rotation of the record disc is normally biased by a spring toward retracted direction and engages the locking bars through a manipulating member. One of the locking bars urges the manipulating member affixed to the center shaft by pushing thereon against the resilient force imparted by the flat spring. In turn the center shaft pushes a sound transmitting member upward and releases stylus force applied to pickup to allow the pickup to return by a return spring to the starting point of sound reproduction. Prior to the engagement of the center shaft and the sound transmitting member, the locking bar projects into the rotational plane of the stopper block and engages with the stopper block such that the record disc is temporarily stopped.

The casing of a sound reproducing device defines the upper and lower bearings for directly receiving a shaft of a driving motor, as well as the outer shell for enclosing the rotor of the motor. This arrangement provides a motor assembly without the need for separate outer shell and separate brackets which are ordinarily indispensable with motors. The rotor hereof has a commutator being matingly electrically and slidably contractable with a pair of brushes fabricated from a metal wire. The free end of each wire comprises the brush, and the remaining portion thereof acts as a lead wire integral with the brush. The contact surfaces of the brushes and the commutator can be displaced or shifted by moving the two mating parts relative to each other for preventing defective starting due to poor electrical connection.

Disclosed is a simplified structure of a toy phonograph in which the output shaft of a motor is selectively put into engagement with the rim of a record disc to drive the latter. A tone arm is provided above the record disc, so that the record disc may be contacted by a stylus carried by the tone arm, when moved axially by the output shaft of the motor brought into driving engagement therewith. The motor is biased for pivotal movement into engagement with the record disc, by means of springs which are retained by terminals of the motor. The springs are made of a conductive and resilient material, for playing a role of lead wire for supplying the motor with power. The springs include a plus side and a minus side springs, one of which is adapted to be separated from the associated motor terminal in the course of the pivotal movement of the motor, to serve as a source switch. The tone arm is normally biased toward the starting point of reproduction, so as to be swung in a space between the record disc and a speaker. When the reproduction is over, the tone arm is displaced radially outwardly or inwardly of the record disc, so as to allow the axial movement of the record disc. During this axial movement the spring comes to be separated by the associated motor terminal to open the source circuit. As a manual switch is depressed, the record disc is lowered to allow the tone arm to return the central starting point of reproduction, and the spring which has been disconnected from the motor terminal is again brought into contact with the latter.

For automatically returning a pickup arm to a predetermined starting position on the perimeter of a record disc on a motor-driven turntable upon completion of playback, a drive gear is mounted on a turntable shaft for simultaneous rotation with the turntable. A driven gear, integrally formed with a cam, is mounted on a pivotal arm for movement into and out of engagement with the drive gear. When the pickup arm travels to a terminal position on the record discs, during playback, the driven gear is thereby urged into engagement with the drive gear and is, thus, set in rotation with the cam. The rotating cam causes the pickup arm to be lifted off the record disc and, then, to be spring returned from the terminal to the starting position. The record disc used herein is of the type having a plurality of grooves formed therein in the shape of nested spirals, for successive or random playback.

Disclosed is a process for producing porous materials by replacing a first solvent in a wet material containing the first solvent with a second solvent in a high pressure condition and drying the resulting wet material which process comprises a mixed solvent feeding step for feeding a mixed solvent composed of a solvent identical to or of the same kind as the first solvent and the second solvent to the wet material.

A hot isotropic pressure device including: a casing disposed inside a high-pressure container; a heating unit provided inside the casing and forms a hot zone around the treatment material, in which an isotropic pressure treatment is performed on the treatment material using a pressure medium gas. A cooling unit is provided to cool the hot zone by guiding the pressure medium gas, cooled while guided from the upper side toward the lower side at the outside of the casing, into the hot zone. The cooling unit includes a gas introducing unit which guides the pressure medium gas cooled at the outside of the casing from the lower portion of the high-pressure container to the upper portion of the hot zone without any intersection with the pressure medium gas inside the hot zone and introduces the pressure medium gas into the hot zone.

A heater plate may be manufactured by receiving a sheath heater within a groove portion formed in a base member made of aluminum or aluminum alloy. At least one joint member made of aluminum or aluminum alloy may be placed into the groove portion so as to fix the sheath heater in the groove portion. The joint member may have two correspondingly tapered portions facing each other which extend toward a lower end thereof such that a distance between the two tapered portions becomes narrower and a width of a surface portion contacting with the sheath heater in the joint member is larger than a width of the sheath heater. The base member and the joint member may be metal-bonded such that a force is added from an upper surface of the base member toward the sheath heater direction, wit the sheath heater fixed in place therebetween.
