Title: Optical disk device
Inventor: SATO YUJI
IPC: G11B7/125
Filed: 1990-10-05
Abstract: PURPOSE:To decrease noise and to execute the control of a laser light output at high speed by applying a feedback to a driving current of a semiconductor laser by a detected value of a front laser light detected by a detecting means. CONSTITUTION:A light beam emitted from a semiconductor laser 11 passes through collimator lens 19 and is divided into two by a beam splitter 12, and a detected light beam is made incident on a photodetector 13 through a condensing lens 20. Its detecting signal 14 is inputted to a control part 28, takes a difference to a reference light output signal 15, is amplified by a compensation amplifier 16 and supplies a driving current to the laser 11. On the other hand, a main light beam which passes through the beam splitter 12 executes recording to an optical disk 18 through a lambda/4 plate 27, a mirror 23, and an objective lens 17. By detecting a reflected light from the optical disk 18 by a photodetector 25 through the beam splitter 12 and a condensing lens 24, a reproducing signal 26 is obtained.

Abstract: PURPOSE:To facilitate a musical performance with expressing power by providing a converting means which converts an operation signal so that control resolution regarding musical tone characteristics becomes high in specific mode among transmission modes. CONSTITUTION:A sound source (i.e., physical model sound source) 8 generates a musical tone signal on the basis of various switch operations and the detection result of a detector and the musical tone is outputted by a sound system 9 consisting of an amplifier and a speaker. This sound source 8 sends the signal in plural (n) transmission modes corresponding to an input signal, which is obtained by converting a signal generated by an operation signal generating means by a converting means. The operation signal is so converted that the control resolution regarding the musical tone characteristics becomes high in one or (m) (n>m) specific modes among the (n) transmission modes. Consequently, the signal generated by the operation signal generating means is assigned in detail over the entire oscillation range in the specific modes.

Title: Coordinate position detecting method
Inventor: ABE TOSHIO
IPC: G06F3/03
Filed: 1986-11-13
Abstract: PURPOSE:To obtain a highly accurate coordinate input device by specifying either of auxiliary electrodes to sandwich a depressed point, operating a depressed point position from the voltage of the specified auxiliary electrode and the voltage of the pressure point and detecting the coordinate position of the pressure point. CONSTITUTION:Plural linear auxiliary electrodes 13 and 14 parallel to respective collecting electrodes 5a, 5b, 8a and 8b are formed at an equal interval, for example, the good electric conductor such as a silver paste on resistance films 4 and 7 of respective resistance sheets 1 and 2. Thus, since plural auxiliary electrodes 13 and 14 are formed, an equipotential line is formed on the resistance films 4 and 7 by these auxiliary electrodes, and at the narrow section between the auxiliary electrodes, the distortion of the equipotential line due to the resistance film thickness difference and the presence of a scratch is compensated by the auxiliary electrode at both sides and comes to be very small. The operation is executed by the voltage measuring value due to the comparatively short resistance part between the auxiliary electrodes 13 and 14 and the voltage value of the auxiliary electrode. Thus, the highly accurate coordinate position detection can be rapidly executed.
