Title: Tracking device
Inventor: ENDOU KENJIROU
IPC: G11B5/588
Filed: 1984-03-22
Abstract: PURPOSE:To simplify the circuit constitution by preventing deterioration of a reproduced output due to overlapped write while realizing tracking and using a pilot signal to attain tracking. CONSTITUTION:A pilot recording region R2 is divided into the 1st and 3rd regions R21, R23 on which the pilot signal is recorded and the 2nd region R22 on which a non-modulation signal is recorded. The three regions R22 of the track A2 is in contact with the 1st region R21 of an adjacent rack B2 at the left side viewed from the head scanning direction x2 and in contact with the 2nd region R23 on the right adjacent track B1. A signal is detected alternately with a time difference in controlling the tracking of the head based on crosstalk information of the pilot signal from both the adjacent tracks by setting the track pattern of the pilot recording region R2 in this way.

Title: Piezoelectric oscillator
Inventor: ONISHI KAZUMASA
IPC: B06B1/06
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric oscillator in which an oscillator can be supported rigidly and stably while eliminating disconnection of wiring. SOLUTION: Both oscillators 10, 11 on the drive side and output side are circular and driven with primary spreading vibration having nodes at the centers O1, O2 on a plane to produce a boosted voltage at an electrode 17 on the output side. Since the oscillators 10, 11 oscillate to have nodes at the centers O1, O2, then can be supported stably at the centers O1, O2 and disconnection can be prevented when the electrode is connected with wiring in the center. Furthermore, spreading vibration having a node at the center can be excited easily when circular oscillators 10, 11 are employed and the impedance can be reduced on the drive side.

Title: Paste type cadmium anode for alkaline storage battery
Inventor: KAWASE RYUJI
IPC: H01M4/62
Filed: 1987-03-11
Abstract: PURPOSE:To increase the conductivity of an active material layer and to improve cycle performance by adding fine electroless nickel plated hollow balls having many pores on the wall to an active material. CONSTITUTION:Fine electroless nickel plated hollow balls having many pores on the wall are added to an active material layer mainly comprising cadmium oxide or cadmium hydroxide. Since the fine hollow balls have conductivity because of nickel plating, the conductivity of the negative active material layer added with the hollow balls is increased and the oxygen gas absorbing capability is also increased. Although the electrolyte poured in a assembly process is retained in an anode, a part of the electrolyte penetrates into the hollow balls through pores on the wall and is retained in the inside of the hollow balls. Thereby, the cycle performance of a battery substantially increased.

Title: Optical apparatus containing mobile optical system
Inventor: TATSUNO TORU
IPC: G11B7/09
Filed: 1985-03-22
Abstract: PURPOSE:To attain a high-speed and accurate action of an optical apparatus containing a mobile optical system even though the extraordinarily large power is applied to the optical system, by using a means which fixes the position of the optical system. CONSTITUTION:A coil driving circuit 32 energizes conduction coils 11 and 12 when the shift acceleration of an optical head is large in the tracking direction, i.e., the shift of the head is started and through in a random access mode, etc. Thus the magnetic substances 14 and 15 are attracted to suppress the shift of a lens barrel 1 toward the main body of the optical head. In addition, a detecting means detects the abnormal vibrations larger than the prescribed value which are produced at a mobile part including plate springs 2-5 and the barrel 1 in case the large power is applied to the main body of the head or the barrel 1. Thus it is possible to suppress an abnormal shift of the barrel 1 toward the head main body produced by an external factor. Then the high- speed response is secured with such an optical apparatus since an electromagnetic means is used as a fixing means for a mobile optical system.

After vapor-depositing nickel-chromium and copper on one side of the substrate, a layer of nickel-tungsten is provided by electroless plating, and the recording needle is formed by photo-etching, thereby producing a recording head. When printing is conducted by the recording head in which the hardness of the recording needle is higher than that of the substrate electrode, the electrode substrate is abraded faster, so that a recording end face of the head is constantly maintained in the condition wherein the recording needle is projected from an end face of the electrode substrate.

Abstract: PURPOSE: To prevent the production of foam owing to the evaporation of a flux in straps and the damaging of plates in the stage of welding the straps to the lug parts of the plates of a storage battery by limiting flux coating parts to specific parts.  
     CONSTITUTION: In the stage of dipping the plate lug 1 of a storage battery into molten Pb 4 in a mold 4, and welding a strap thereto, a flux 2 is coated near the contact boundary face of the lug 1 and the molten Pb according to the height of the lug to be dipped in the molten Pb 4 without coating the flux 2 over the entire surface of the welding surface of the lug 1.

Filed: 1980-04-30
Abstract: PURPOSE:To make controlling of titled values possible relatively and easily by quenching and tempering Ni-contg. steel and controlling old austenite grain sizes and the amount of austenite measured under specific conditions. CONSTITUTION:Steel contg. 7.5-10.0wt% Ni is quenched once or more to the prestructure of martensite and lower bainite and is tempered once or more to uniformly form fine austenite.
