Abstract: A vibration monitoring device includes: a rotation sensor for outputting a rotation signal synchronized with rotation of a rotational shaft; an output device for outputting a filter command value corresponding to a rotation speed of the rotational shaft calculated from the rotation signal; and at least one filter for extracting, in response to input of the rotation signal and the filter command value, a signal in a passband set according to the filter command value from the rotation signal as a vibration signal from which vibration information of the rotational shaft can be obtained.

Abstract: Disclosed is a drawing toy which includes a plurality of light transmitting carriers that are manually movable past a writing platen which supports portions of the carrier. Each carrier has on its surface a series of different figure fragments which inhibit light from passing through the carrier where a figure fragment is displayed. Selectively moving the carriers to the platen positions different figure fragments over the platen. There is a light source adjacent to the platen and on the side of the platen opposite the carrier so that light passes through the platen and then through the carrier. Preferably, a transparent protective member overlies the portion of the carriers supported by the platen, with the carriers being sandwiched between this member and the platen. A translucent sheet of paper is placed over the protective member opposite the platen.

Abstract: A toy stove assembly includes a housing member configured to simulate a stove with an upper burner portion. A cooking vessel has an apertured false bottom connected to a conduit that extends to the exterior of the cooking vessel. Pressurized air is generated and connected to the conduit so that the air can be introduced into the cooking vessel to simulate boiling of any liquid substance in the cooking vessel. A toy kitchen sink can also optionally be included with the same motor that provides the pressurized air providing a pumping action for delivering water through a faucet.

Abstract: A toy having a chassis generally configured to simulate a cash register and a mechanism for numerically displaying a price of specific merchandise depicted on a card, is disclosed. The mechanism includes a first and a second panel of the chassis which define a slot wherein the card is at least partially positioned for pictorially displaying the merchandise. A member or plate positioned in the slot supports the card in its position wherein the merchandise is pictorially displayed. The member or plate may be removed through a child actuated lever mechanism to allow disposition of the card behind a plurality of transparent portions of the first panel. The transparent portions of the first panel are configured and adapted for displaying a plurality of numerals when reflection of light is blocked in predetermined parts of the transparent portions.

Abstract: A toy device adapted for threading beads upon a thread or line is disclosed. A container for beads is mounted to a preferably transparent chassis. The container has an outlet port or hole in a lower part thereof through which beads may fall out of the container one-by-one. A first end of the guide wire or like member is mounted substantially in the center of the outlet port. The container is continuously shaken through a hand actuated crank and ratchet gear assembly. As a result of the shaking, the beads undergo a random motion which eventually causes the beads to fall one-by-one through the outlet port onto the guide wire with the guide wire substantially centered in the central aperture of each bead. A bead advancing assembly which comprises two rotatable members having cut-away portions to capture the beads, is operatively associated with an intermediate portion of the guidewire.
