Title: Digital signal reproducing device
Inventor: YOKOZAWA SEIICHI
IPC: G11B15/467
Filed: 1986-07-29
Abstract: PURPOSE:To prevent a capstan servo from disturbance by correcting the level difference of cross-talk by the sample holding levels of pilot signals on an on-track, and when a level generated before and after sampling to be executed in accordance with a sink signal is not proper, inhibiting control. CONSTITUTION:The levels of pilot signals on an on-track which are obtained by rotary heads 1A, 1B are sampled and held and the level difference of cross- talk between pilot signals on both adjacent tracks is corrected by a decoded data processing part 17 on the basis of the held level. Whether the levels of pilot signal frequency components outputted from respective rotary heads 1A, 1B before and after sampling executed in accordance with the detection of a sink signal is proper as the cross-talk of pilot signals on one adjacent track or not is decided. Whether the level difference of the cross-talk is supplied to a capstan servo 8 as a signal indicating a track shear variable or not is determined. Consequently, the capstan servo 8 can be prevented from disturbance due to the dispersion of the rotary heads or the erasing residual of the sink signal.

Title: Optical pickup
Inventor: FUJISAWA SHUJI
IPC: G11B7/085
Filed: 1985-08-09
Abstract: PURPOSE:To adjust easily the optical axis of a light source to a photodetecting member and to improve the control job efficiency by providing a position detecting part to an objective lens together with a position detecting light source and the photodetecting member centering on said position detecting part and furthermore supporting rotatably the position detecting light source by a fixing member. CONSTITUTION:In response to the shift of an objective lens 34 caused by a high-speed access operation, etc. in the tracking direction T, a position detecting member 42 displaces. Then the distribution of the light quantity delivered from a light emitting element 41 and received by a photodetecting element 39 is changed by a detecting part 44. In case the lens 34 has no displacement, the control is previously given so that the coincidence is secured among the optical axis of the element 41, a dividing line 39c of the element 39 in the direction T and the center of the part 44 respectively. Thus the difference of output voltage goes to '0' between the photodetecting areas 39a and 39b of the element 39. While the distribution of the light quantity is proportional to the displacement of the part 44 when the lens 34 has a displacement. Then the difference of output voltage between both areas 39a and 39b is proportional to the displacement of the lens 34.

Title: Joint bolt-seal for caterpillar track
Inventor: HERUMAN METSUNAA
IPC: B62D55/20
Filed: 1982-10-07
Abstract: A joint pin seal for a caterpillar track. The join pin seal comprises a support ring of hard elastomer material having a cylindrical inner wall. The support ring is firmly pressed in a housing bore which is adjacent a relatively movable machine part to be sealed. The support ring comprises a stiffening ring contacting the rear wall of the housing bore and a lip ring adjacent the machine part to be sealed. The lip ring has a sealing lip which presses against the surface of the machine part to be sealed. The stiffening ring is tapered in notch-like fashion into said lip ring forming a membrane at the transition into the lip ring and provides the support ring with a notch between the lip ring and the stiffening ring. A pressure ring, formed from a softer elastomer material, is disposed within the notch and contacts the housing bore wall. The pressure ring presses the sealing lip into the relatively movable machine part to be sealed. The ratio of the average radial distance from the membrane to the sealing lip to the average radial distance from the center line of the pressure ring area contacting the lip ring to the sealing lip is about 0.7 to 1.4.

Title: Electronic musical instrument
Inventor: FUJII KATSUYOSHI
IPC: G10H1/00
Filed: 1987-07-16
Abstract: PURPOSE: To attain electronic musical instrument performance with a voice without any keyboard by detecting the fundamental frequency from a speech signal, and synthesizing musical sounds in a sound level corresponding to the fundamental frequency. CONSTITUTION: For example, time data inputted by a time length/frequency converting table 9 constituted of an ROM are converted into frequency data, and the output is transmitted to a musical sound synthesizer 11. On the other hand, the output of a smoothing circuit 5 is transmitted to a first comparator 6, compared with a comparison voltage, and the compared result is added to the synthesizer 11 as a utterance/stop signal. Musical sounds corresponding to the inputted frequency data and volume data are synthesized by the synthesizer 11, and outputted from a terminal 12. That is, the synthesizer 11 synthesizes the musical sounds corresponding to pitch frequency being the basic frequency of the voice input signal and the volume, and utterance data are transmitted to the synthesizer 11 only when the amplitude of the signal components passing through a filter 3 of the voice input signal is larger than the comparison voltage. Thus, when the speech signal does not include any vowel, that is, the speech signal includes only consonants, the musical sounds are not synthesized, and the musical sounds corresponding to the vowel are synthesized.
