Title: Ribbon reel
Inventor: INOUE YOJI
IPC: B41J17/02
Filed: 1991-01-28
Abstract: PURPOSE:To wind a ribbon at a constant tension without using a ribbon feed drive roller even if a ribbon diameter is increased in an ink ribbon take-up reel or the like in a thermal transfer printer. CONSTITUTION:A friction clutch 13 for transmitting a rotating force using a reaction force of a spring 13c is provided on a reel 10. An abutting member 16 is provided so as to abut on the peripheral surface of a ribbon. A transmission member 15 for transmitting the reaction force of the spring 13c to the abutting member 16 is provided. As a ribbon diameter is increased, the abutting member 16 is radially moved.

Title: Conductive dust sensor
Inventor: MAKITA FUTOSHI
IPC: G01N27/04
Filed: 1985-02-14
Abstract: PURPOSE:To detect instantaneously fine dust by disposing conductors at fine intervals on an insulator substrate and detecting the change of a resistance value or current value owing to a short circuit as a result of the contact with the dust. CONSTITUTION:The substrate 1 is formed of a material having a small coefft. of thermal expansion, for example, quartz glass, etc. The conductors 2 having the resistance value larger than the conductive dust to be detected are disposed at the fine intervals. The intervals are made adequately about <=1/3 the diameter of the dust. The pattern of the conductors 2 is made square, circular, etc. The change of the electric resistance or current value of a conductor juncture 3 is detected when the dust contacts with the conductors 2 and short-circuits the conductors 2. The instantaneous detection is thus made possible as the fine dust is detected by the conductors which are disposed in a large area.

Title: Keyboard device for electronic musical instrument
Inventor: MISHIMA JUNICHI
IPC: G10H1/34
Filed: 1990-02-07
Abstract: PURPOSE:To obtain a touch feeling of real playing like a natural acoustic piano by composing a control means of a magnetic field production member and a conductor, and fitting one to a key support member and the other to a key associated member so that relative displacement is enabled. CONSTITUTION:The control means 22 consisting of the magnetic field generating member 21 and a conductor 20 is provided between the key support member 3 and a key 1 or the key associated member 5 which is displaced associatively with the key, so when the key is pressed, the magnetic field generating member 21 and the conductor 20 are displaced relatively to generate an eddy current on the opposite surfaces, thereby generating a braking force. Accordingly, the generated braking force is larger as the relative displacement speed between the member 21 and the conductor 20 is faster and the braking force is smaller as the relative displacement speed between the both is slower, and its dynamic range becomes wide. Consequently, touch pressure is small when the key is pressed weakly and large when the key is pressed strongly to obtain the touch feeling of real playing like the natural acoustic piano.

Abstract: PURPOSE: To prevent paper from being pulled by a printing head and improve the connection accuracy of each print line by pressure-fitting and fixing the side ends of paper to a platen on the moving path of a printing head. CONSTITUTION: With a paper presser 28 raised from a platen 14, paper 16 such as a web is transported onto the platen 14. When printing begins, a printing head 12 moves onto the platen 14 in a raised state, along a rail 8, and starts printing. A lifting means 24, sucked into the inside of an actuator casing, swings counterclockwise around a shaft 26 and the paper presser 28 presses the paper 16 to the platen 14 from above. And then the printing head 12 comes down and touches the paper 16 at a starting point S on the platen 14. The side of the paper on the print starting point side is pressed and fixed onto the platen by the paper presser 28 on the moving path of the print head. Therefore, even if pulled by the print head, the paper does not slips.

Title: Photo-switch
Inventor: NISHIO MITSUO
IPC: H01H35/00
Filed: 1990-02-07
Abstract: PURPOSE:To enable easy checking of ON/OFF operation of a photo-switch with eyes at a site where it is used by providing a light shutter with a reflection face which leads the light beam incident on a prism body at the switch OFF position to the outside of switch case via a light projection optical fiber after reflecting it in the direction substantially vertical to the shutter. CONSTITUTION:A reflection face 6a reflects the light beam incident on a prism body 4 at the OFF operation position of switch through a light projection optical fiber 2 in the direction substantially vertical to a light shutter 6 to lead it to the outside of a switch case 1. When the shutter 6 is moved to the switch OFF position with the operation of an actuator 5, the light beam incident on the prism body 4 via the light projection optical fiber 2 is reflected on the reflection face 6a to change the direction thereby being led to the outside of the case 1 via a light leading hole opened at the actuator 5. It is thus possible to enable easy checking the operation of a switch and whether it works normally through eyes and to widen the function of the switch.

Title: Optical-disk recording apparatus
Inventor: GUSHIMA TOYOJI
IPC: G11B19/26
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To obtain an optical-disk recording apparatus by which data can be recorded with good quality even with reference to an optical disk which depends on a linear velocity. SOLUTION: A wobble binarized signal 305 which binarizes a signal corresponding to the meandering cycle of a wobble group formed on an optical disk is input to a linear-velocity-information extraction means 112. The linear- velocity-information extraction means 112 extracts a present linear velocity by measuring the cycle of the wobble binarized signal 305. According to extracted linear-velocity information, a system control means 110 performs a pulse-shape setting operation 307 in order to make the shape of recording pulses 206a, 206b, 206c by a recording-pulse generation means 111 variable or performs a power setting operation 205 in order to make recording power by a laser drive means 108 variable.  By this constitution, since a laser light- emitting waveform can be controlled according to the extracted linear velocity, an optimum recording condition can be always set without depending on a linear velocity.
