摘要:
A SAW filter includes a first SAW resonator having a pair of terminals and a predetermined resonance frequency (f.sub.rp), the first SAW resonator being provided in a parallel arm of the SAW filter. A second SAW resonator has a pair of terminals and a predetermined resonance frequency (f.sub.rs) approximately equal to a predetermined antiresonance frequency of the first SAW resonator (f.sub.ap). The second SAW resonator is provided in a series arm of the SAW filter. An inductance element is connected in series to the first SAW resonator.

An operator inputs design information including shape information and stitch structure information of a fabric to be knitted by a keyboard input unit and a coordinate input unit. An engineering workstation prepares a fabric image showing the state of a finished fabric on the basis of these information, displays it on a color display, and converts it to sequence data indicating the knitting operation sequence of the fabric (knitting machine) and control data indicating the control operation of the knitting machine, respectively.

A cassette loading apparatus for a cassette playing/recording apparatus such as a DAT, VCR, or optical disc apparatus, includes guide slots in a frame for guiding a cassette holder between an insertion position and a loading position, and an opening-closing guide slot for guiding a link lever coupled to a release lever for opening and closing a lid on the cassette as the cassette holder moves between the insertion and loading positions. The opening-closing guide slot includes a yieldable arm for guiding the link lever along the guide slot during normal operation, and for flexing downward in the event that the cassette lid accidentally disengages from the release lever when moving from the loading position, so as to prevent the cassette from becoming jammed in the apparatus and to allow the cassette to be transferred to the insertion position from which it can be removed.

The present room temperature curing composition comprises an organopolysilethylenesiloxane represented by the following general formula: ##STR1## wherein R.sup.1 to R.sup.4 each represent an alkyl having up to 8 carbon atoms or a phenyl group and n is an integer of 10 or above, and an organosilane or an organosiloxane having two or more hydrolyzable groups such as alkoxy groups in the molecule. The composition can form a cured product high in rubber strength and excellent in chemical resistance.

A toy assembly that can be converted into either a toy gun or robotic humanoid assembly is provided. A handle member can be reconfigured to simulate the robotic legs, while the gun barrel member can be reconfigured to simulate the robotic arms. A trigger frame assembly can be positioned adjacent the handle member and the gun barrel member when simulating the configuration of a gun or can be rotated when simulating a robot. The configuration of a toy gun can fire actual pellets.
