Title: Three phase three leg core
Inventor: KASHIMA YOSHITAKE
IPC: H01F27/245
Filed: 1980-10-22
Abstract: PURPOSE: To reduce a core loss by a method wherein upper and lower layers are made of a trapezoidal steel plate and the steel plate is cut vertically or diagonally, a main leg is permitted to be coupled diagonally or at an vertical angel with the steel plates of the upper and lower yokes which are made of a steel plate cut diagonally 45° or less and an external leg is made of a steel plate cut diagonally.  
     CONSTITUTION: Upper and lower yokes 1, 2 comprise steel plates 7, 7' cut diagonally 45° and 45°-α at the corner and steel plates 8, 8' cut 45° and 90° at the corner respectively. The width W ξ  of the yokes is greater than that WC of a main leg. The main legs 3 through 5 are have a small width, external legs 3, 4 are made of a steel plate cut diagonally 45° and a central leg 5 consists of a steel plate cut diagonally in a condition of 45°>α. The steel plate of the legs 3 through 5 and the upper and lower yokes 1, 2 are alternately laminated to form a desired assembly. According to the above constituion, the excessive chip steel plates are removed completely. Since the width of the upper and lower yokes is measured greater than the legs, a magnetic flux density in the coupling portion decreases and a rising of core loss and temperature can be suppressed. Whereby the core assembly can be minimized appropriately.

Title: White balance adjuster for color video camera
Inventor: SUURA HIROAKI
IPC: H04N9/73
Filed: 1984-07-16
Abstract: PURPOSE:To improve the answering ability of an object subjected to the white balance adjusting to color temperature by changing a mixing ratio of color temperature signals from plural color temperature detectors in accordance with a zoom magnification of an optical lens system and outputting said signals. CONSTITUTION:When an optical lens system 1 is in the state of a telephoto lens, a signal corresponding to a zoom magnification of a zoom magnification detector 7 is given to a mixing ratio changing mixer 8. Since a picture angle is small when the zoom magnification is large, color temperature signals are mixed so that a mixing ratio of a color temperature signal from a color temperature detector 6a having a light-receiving part with a small natural lighting angle can be larger than that of a color temperature signal from a color temperature detector 6b having a light-receiving part with a large natural lighting angle. Levels of a red signal in a white balance adjusting red signal variable gain amplifier 4a and a blue signal in a white balance adjusting red signal variable gain amplifier 4b depend further on the color temperature signal from the color temperature detector 6a having the light-receiving part with a small natural lighting angle, and is adjusted.

Title: Solid slab laser
Inventor: TADA TERUSHI
IPC: H01S3/23
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To set uniformly and isotropically the aspect ratio of the sectional form of a laser emitted beam to the divergence angle of the laser emitted beam in a solid slab laser. SOLUTION: A slab laser crystal 101 has the end surfaces 107 and 108 and the optically smooth surfaces 103 and 104, which are slanted to an optical axis 111, a slab laser crystal 102 is also formed into the same shape as that of the crystal 101 and is rotated at an angle of 90 degrees and the planes that the respective zigzag optical paths in the crystals 101 and 102 form with the crystals 101 and 102 intersect each other at an angle of 90 degrees. A resonator is constituted of an output mirror 121 and a high reflecting mirror 122. A laser beam incided in the crystals 101 and 102 through the slanted end surfaces traces a zigzag path in the direction (y) within the crystal 101 and traces a zigzag path in the direction (x) within the crystal 102. Owing to this, as a laser optical path 112 follows the zigzag paths in both directions of the directions (x) and (y), the conditions of the resonator become equal with each other also in both directions of the directions (x) and (y) and the aspect ratio of the sectional form of a laser emitted beam to the divergence angle of the laser emitted beam is also set isotropically.

Abstract: PURPOSE:To sufficiently restrain a driver after an air bag is developed, by installing a means for preventing the expulsion by pressing the leg part of the driver from outside to the inside after the development of the air bag is completed and a means for restraining the vicinity of the center of gravity position of the driver. CONSTITUTION:When collision occurs, a collision sensor senses collision, and sends signals into an air bag 5 and an operating switch 14. Then, the air bag 5 is developed, and performs initial restraint for a driver. While, the operating switch 14 pulls out an arm lock pin 13 and separates an arm 3a from a frame 6. Then, the arm 3a starts turn by the strong springy forces of springs 9 and 10.

Title: Substrate bias voltage generator circuit
Inventor: HIRATA MASAKI
IPC: G05F3/24
Filed: 1977-12-13
Abstract: PURPOSE: To apply fully large substrate bias by setting up the second driving circuit reversely operates with the first driving circuit so that the discharge period of the former corresponds to the discharge period of the letter.  
     CONSTITUTION: The waveform at the output point A of an oscillator is reverse with that of the output point B of a phase shifter to each other. Since the waveform of the output point C of the first driving circuit changes a load transistor 17 into a depletion type, amplitude rises up to the power supply voltage. The waveform at a point D is clamped to the treshold value voltage by a clamping diode 21 and becomes a negative pulse. When the potential at the point D is lower than that of a substrate 22, i.e. lower than the threshold value voltage, a charging diode 20 is energized. Current is applied to the point D from the substrate 22 and the substrate 22 is biased to negative voltage. It is inergized during the semiperiod of oscillation and charge is discharged at the remaining semiperiod. The waveform at a point E is inverse in a phase with that at the point D.
