Abstract: In a cartridge loading mechanism, a carrier is arranged on the upper side of a cartridge holder for storing a cartridge having a recording medium. A loading base is arranged on an upper side of this carrier. This cartridge holder and the carrier are attached to a swinging cam. Further, this swinging cam is swingably attached to the loading base. The cartridge holder is vertically moved in association with a horizontal movement of the carrier. The cartridge holder is reciprocated between an inserting/discharging position of the cartridge and a chucking position of a spindle motor. Thus, the body of a drive unit can be made thin while dustproof performance is secured.

The bag is in contact with both the circuit component and the metal shield, and can thus absorb heat from the circuit component and transmit the heat to the metal plate.

Abstract: A method and apparatus for automatically tightening and untightening bolts which are assembling and fastening devices for a form used in centrifugal compacting and molding concrete products, in which engaging members are brought into engagement with rotary supports which support the form. A bolt tightening and untightening mechanism is moved with the rotary supports, and the bolts are automatically tightened and untightened during the movement thereof. Engaging members are operated more than a dimensional difference of the rotary supports so that even if dimensions of the rotary supports are different according to the kind of the form, the engaging members can be positively engaged with the rotary supports, or the bolt tightening and untightening mechanism is moved up and down in advance so that a height position thereof becomes a predetermined height with respect to the rotary supports.

Abstract: Disclosed herein is an electronic apparatus having a keyboard and a display unit and having a base unit made of a synthetic resin. The base unit comprises an upper case having a top wall and a peripheral wall, and a lower case having a bottom wall and a peripheral wall. The peripheral walls of the upper and lower cases are connected. A storage space is formed between the upper case and the lower case, for containing a battery pack. A loading port is formed in the sides of the upper and lower cases, communicating with said storage space. Though this port, the battery pack can be inserted into, and removed from, the storage space. A cover is connected to the base unit. It can move between a port-closing position where it closes the loading port and a second port-opening position where it opens the loading port. The cover has a top wall slidably mounted on the top wall of the upper case, and a lower wall slidably mounted on the bottom wall of the lower case.

Abstract: A camera has a shutter which may also constitute a diaphragm. In a multi-flash mode the shutter selectively has a maximum aperture at an onset or at the end of the time base. The flash occurs in synchronism with a shutter waveform shaped by this aperture area and a time base element. In a second embodiment, a second diaphragm setting circuit is provided, in diaphragm priority photography, for computing a measurement value of a distance to a subject and a second diaphragm value from the guide number during an emission of flashed light. The diaphragm is set to the computed second diaphragm value, ad an electronic flash is energized with a desired aperture area. The diaphragm is set to an initial value to effect the photography at a time other than during the emission of flashed light. A timing circuit may be provided for setting the diaphragm to the second diaphragm value.

Abstract: A refrigerator having a refrigerant circulating circuit for circulating a mixture of a refrigerant and a refrigerating machine oil. The refrigerator includes a compressor with a bypass circuit or a variable displacement compressor, a state detecting sensor for sensing the degree of separation of the refrigerant mixture, determining circuit for determining whether the detected degree of separation is in a two phase separation area, and a control unit for controlling the amount of the refrigerant passing through the bypass circuit or the displacement of the variable displacement compressor. When the refrigerant mixture enters into the two phase separation area, the amount of discharge or the displacement of the compressor is decreased. The temperature of refrigerant mixture is lowered accordingly and the phase changes from the two phase separation area. The refrigerating machine oil is maintained in a uniformly mixed state with the refrigerant and circulates with the refrigerant to the compressor.

The loading apparatus may further has a stopper for restricting an operating range of the head escaping device. An ejecting operation of the disk cartridge is performed at a latter operating stroke of the ejecting knob in a state in which the recording-reproducing head is escaped from a recording disk. The loading apparatus may further has a slanting cam groove having a horizontal portion in a central portion thereof and formed in a carriage for operating the head escaping device. The ejecting operation of the disk cartridge may be performed at the latter operating stroke of the ejecting knob provided by the horizontal portion of the slanting cam groove.

Abstract: An ejection inhibiting mechanism in a disk memory device of a meidum exchanging type has a latching solenoid for inhibiting the operation of an ejecting mechanism for ejecting a memory medium; an inhibit releasing device for releasing the inhibition of the operation of the ejecting mechanism by the operation of the latching solenoid when a predetermined time has passed after power of the disk memory device is stopped; and a storage battery charged at any time and supplying power to the latching solenoid and the inhibit releasing device. The operation of the ejecting mechanism is inhibited until the rotation of the memory medium is stopped. A cartridge for a disk constructing the memory medium is ejected after the power of the disk memory device is turned off and the rotation of the disk is completely stopped. An attractive state of the latching solenoid is released when the predetermined time has passed.
