Title: Formation of polycrystalline silicon thin film
Inventor: KUDO ATSUSHI
IPC: H01L21/84
Filed: 1985-09-14
Abstract: PURPOSE:To facilitate nucleation and grain growth in a silicon thin film and obtain high quality polycrystalline silicon thin film at a low substrate temperature, by growing a silicon thin film on a noncrystalline insulating substrate via an intermediate layer composed of a polycrystalline insulating film. CONSTITUTION:On a non-crystalline insulating substrate 6, such as borosilicate glass, an intermediate layer 4 composed of polycrystalline insulating thin film is formed, and on the intermediate layer 4, a polycrystalline silicon thin film 5 is formed in the condition where the temperature of substrate 6 is lower than 500 deg.C. From structural viewpoint, the intermediate layer 4 requires stable material with respect to the reaction property against silicon and the thermal resistance, and its film purity must be higher than 99.99% (4N). In case of large mismatching with silicon, thee is possibility that nucleation and grain growth in a polycrystalline silicon thin film 5 are apt to be interrupted, so the lattice matching within + or -15% to 5.43Angstrom  which is the lattice constant of silicon (011) face, is required. For the intermediate layer 4 satisfying these conditions, CaF2 of fluorite structure and the like are cited as an example.

Title: Optical system for optical information recording/ reproducing device
Inventor: MATSUOKA KAZUHIKO
IPC: G11B7/09
Filed: 1990-08-02
Abstract: PURPOSE:To attain stable APC control and AT (auto-tracking) control by a simple constitution by extracting a part of beams directed to a recording medium, detecting the extracted beams by a photodetector and obtaining a control signal. CONSTITUTION:Beams 21 radiated from a semiconductor laser are reflected by a galvanomirror 1 and turned to reflected beams 22 directed to the recording medium. A part of the incident beams 21 is transmitted through a transmitting aperture 4 formed on the mirror 1 as beams 24 directed to a spatial pattern 25 and the outputs 11, 12 of sensors 5, 6 are sent to a sum signal computing part 7 and a difference signal computing part 8. Since a sum signal 13 is changed when the light quantity of the incident beams 21 is changed, the sum signal 13 can be used as a stable APC signal. On the other hand, a difference signal 14 is sensitively changed in accordance with the rotation of the mirror 1, so that the rotational angle of the mirror 1 can be detected. Thus, the offset of an AT control signal due to the rotation of the galvanomirror 1 is removed by the simple constitution.

Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To save the total power as a system in a sleep state by shifting an option device to the sleep state as well, in accordance with the shifting of a recorder to the sleep state. SOLUTION: When a power control means 501A interrupts a prescribed driving system power source in a recorder main body 501, to perform shifting to the sleep state, an informing means 501B outputs a state signal different from a control signal outputted to a control bus 105, to the option device 100 for executing prescribed expansion processing, to inform the option device 100 that the sleep state is in execution, so that the option device 100 surely recognizes that the recorder 501 is shifted to the sleep state. For instance, the frequency of a watchdog input signal outputted from the recorder 501 is changed so that the option device 100 recognizes that the recorder 501 is in the sleep state and when the recorder 501 is in the sleep state, the power source of the option device 100 is interrupted to cut off power supplied to a driving system.

Title: Shaft fixing type motor
Inventor: ISHIZUKA YUTAKA
IPC: F16C33/12
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To provide a shaft fixing type motor which can maintain a long service life and is recyclable at a low cost when the life is ended. SOLUTION: In a shaft fixing type motor 1, since the inner peripheral surface 410 of a shaft hole 41 formed in a rotating pat member 4 is harder than the outer peripheral surface of 31 of a fixing shaft 3, the inner peripheral surface 410 of the shaft hole 41 does not wear when dynamic pressure generating trenches 71, 72 are formed on the outer peripheral surface 31 of the fixing shaft 3. Since the inner peripheral surface 410 of the shaft hole 41 is smooth, the outer peripheral surface 31 of the fixing shaft 3 is hard to wear down. Thereby the life of the dynamic pressure bearing mechanism 7 constituted between them can be made long. When the fixing shaft 3 wears down and the service life is ended, only the fixing shaft 3 is removed from a motor frame 2, and the other part members can be recycled.  The fixing shaft 3 is fixed to the motor frame 2 by using fastening screws 11, so that the exchange of the fixing shaft is easy.

Title: Printer
Inventor: NISHIKAWA AKIRA
IPC: B41J2/06
Filed: 1985-09-17
Abstract: PURPOSE:To eliminate fouling of a recording material by forming a recording electrode with conductivity on an ink feeder having insulation and ink containing properties, providing an opposed electrode which is positioned opposite to the tip of a recording electrode through a recording material and applying a constant voltage between the two electrodes according to an image signal. CONSTITUTION:An ink feeder 37 is entirely immersed in ink 32 of an ink tank 33, so that ink 32 is supplied to the tip of a recording electrode 36 through the ink feeder 37. If a printing head 13 transmits a printing signal under a condition where said head is set in 'printing ready position', the signal is selectively transmitted to a high-tension switch 39 from a printing control circuit 42, and therefore, a potential difference generates between the recording electrode 36 and an opposed electrode 14 by a high-tension power supply 40, 41. At the same time, ink 32 at the tip of the recording electrode 36 is sent flying toward the opposed electrode 36. In the meantime, if the ink feeder 37 protruded through an electrode hole 38 contacts recording paper 15, the ink 32, held by the ink feeder 37, does not adhere to the recording paper 15. Consequently, it is possible to perform printing using a simple-structure device without fouling a recording material significantly.
