Title: Head position controlling method
Inventor: YAMASHITA TATSUMARO
IPC: G11B5/592
Filed: 1985-06-11
Abstract: PURPOSE:To decrease the number of heads to be used, to obtain a recording pattern being faithful to a format, and to execute a variable speed reproduction so that a reproducing output becomes maximum, by reading a supply voltage corresponding to a rotational direction position of a rotary magnetic head from a memory, and controlling a position of the axis of rotation direction of the rotary magnetic head. CONSTITUTION:A mode signal MOD is impressed to an address generator 33, and an address corresponding to a selected mode and a position of a rotational direction of the present rotary drum 31a, namely, a head is generated. As a result, a supply voltage corresponding to the mode and the head position is inputted to a D/A converter 35. This supply voltage is D/A-converted by the D/A converter 35, smoothed by a low-pass filter 36 and inputted to an actuator 37. The actuator 37 impresses the inputted supply voltage to a piezoelectric element, and moves the head to a prescribed position in the revolving shaft direction in which its reproducing output becomes maximum. Thereafter, the rotary drum 31a rotates and a position control of the head is executed.

Abstract: PURPOSE:To synthesize easily cubic boron nitride (BN) of high quality by placing boron as a simple substance and NH4F in a contact state and treating them under conditions of temp. and pressure in the range where cubic BN is thermodynamically stable. CONSTITUTION:A graphite pipe 2 as a heater and a sleeve 3 as an insulator are successively placed on the inside of a sample vessel 1 of pyrophyllite in a contact state. A metallic capsule 8 filled with a sample 4 prepd. by uniformly mixing boron powder with NH4F is inserted in the sleeve 3, and covers each consisting of a high m.p. metal 7 and a refractory 6 are fitted to the upper and lower ends of the vessel 1 with insulating plates 5 in-between. The covers double as electrodes for supplying electric current. Said components in the tightly sealed vessel 1 are then treated at >= about 1,400 deg.C under >= about 6GPa pressure to obtain yellow cubic BN crystal of high purity. The temp. and pressure can be reduced to >= about 1,350 deg.C and >= about 5.5GPa by placing a catalyst for transition from hexagonal BN to cubic BN such as metallic Al, AlN or metallic W in contact with the sample 4.

Abstract: PURPOSE:To calculate a highly accurate ophthalmic refraction value, by irradiating the center part of an eyeball and that of the eyeground with spot light and taking out the reflected luminous flux thereof from the periphery of the pupil to form ring- shaped luminous flux and forming an image on an area sensor. CONSTITUTION:The luminous flux emitted from a light source 1 passes through a lens 4, a circular iris 3 and the aperture part of a perforated mirror 2 and further passes through the center part of the pupil Ep of an eye E to be examined to project spot like luminous flux on the eyeground Er. The reflected luminous flux thereof again passes through an objective lens 1 and is reflected by the perforated mirror 2 to obtain a ring-shaped image on an area sensor 8 by an image forming optical member 8 through a lens 6 and a ring-shaped iris 7. The dimension and shape of the ring-shaped image obtained on the area sensor 9 are changed according to the degree of pseudomyopia, hypermetropia or astigmatism and, for example, in the case of hypermetropia, a ring-shaped image Ib having a diameter larger than that of the ring-shaped image Ia in the case of stigmatism is obtained and, in the case of astigmatism, a ring-shaped image Ic becomes oval and a degree of astigmatism can be calculated from the ratio of the long and short diameters of an oval and the angle thereof can be calculated from the diameter line direction of the oval.

IPC: G02B21/00
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To restrain effects on pulse contour by a nonlinear effect to the minimum by providing a means for increasing the average power of radiation connected to a microscope, at the terminal of an optical fiber viewed in an illuminating direction. SOLUTION: Cross section of a fiber is made large in order to lower the intensity at the terminal of the fiber so that the non-linear effect is avoided. It is advantageous, especially, to incorporate an element dispersing a laser beam strongly in a laser scanning microscope, instead of the fiber whose cross section is increased. Various kinds of prisms or a grating compressor and further a substance made of special glass material or crystal and incorporated in an acousto-optical device is fit to the element. The radiation of a short pulse laser KPL is connected to a glass fiber 14.1 and above all, to a single mode glass fiber. A pre-chirp unit PE is arranged between the laser and the optical fiber. An acousto-optical modulator (AOM) is arranged at the input part of a scanning module.

Abstract: PURPOSE:To prolong the service life of sealing members of a submergible motor and to prevent leakage of oil, by constituting an oil reserving chamber communicated with a speed-reducing chamber of the pump with a resilient material shaped in the form of a bag, and communicating a chamber incorporating therein the resiline bag-like member with the outside of the apparatus. CONSTITUTION:A chamber 18 having therein a resilient member 16 is communicated with the outside of the apparatus via a connecting port 19 formed in the body 14 of the apparatus, while an oil reserving chamber 17 is communicated with a speed-reducing chamber 12 via a connecting port 24 formed in an annular member 15. In using the motor under a deep water, pressure in the oil reserving chamber is kept substantially equal to that on the outside of the apparatus since water on the outside of the apparatus is introduced into the chamber 18 through the connecting port 19 formed at a prescribed position of the body 14 and exerts a pressure to the resilient member 16. Resultantly, pressure of the oil side respectively of sealing members 27, 28, 39, 40 and that on the water side on them become substantially equal to each other. Thus, it is enabled to prevent degradation of lubricating function due to mixing of water into oil and pollution of environmental water due to leakage of oil into water, so that the motor can be operated efficiently.

Title: Bulb lighting confirming device
Inventor: BAN ITSUKI
IPC: G09G3/04
Filed: 1982-07-22
Abstract: PURPOSE:To achieve safety driving through a car light lighting confirmation device, by utilizing the filament resistance variation under lighting to detect and alarm the blow-out of bulb or the shortcircuit. CONSTITUTION:Upon closing of a power source switch 9, bulbs 3a, 3b will light and since the resistance of each filament is low at the initial conduction stage the input to the terminal 5b of a comparator 5 will be low to produce high level output and the output of AND gate 8 will energize a buzzer or an indication lamp through an amplifier circuit 8a. Upon increase of the filament temperature to steady state, the input to the terminal 5b will increase to the referential voltage from the terminal 5a thus to flicker the alarm signal from an alarm 10 and to confirm the lighting state. When any one of the bulbs 3a, 3b is blown off, the combined resistance will be doubled to increase the input voltage at the terminal 5b while upon occurrence of shortcircuit, the output from an operational amplifier 2 will disappear to bring the input voltage at the terminal 5b to zero thus to function the alarm 10.
