Title: Switching power amplifier circuit
Inventor: NODA HIROSHI
IPC: H03F3/20
Filed: 1987-12-04
Abstract: PURPOSE:To decrease a power loss at the time of no signal and, simultaneously, to execute a direct current amplification by providing a polarity detecting circuit, a gate circuit and a communicating circuit which are equipped with prescribed functions, respectively. CONSTITUTION:A polarity detecting circuit 60 detects the polarity of an input signal Si, and it causes a gate circuit 70 to execute on/off actions according to such a detecting signal. By the on/off of the gate circuit, the actions of first and second output switching transistors 80 and 81 are regulated. A communicating circuit 90 supplies a current by an energy remaining at a coil 101 of a smoothing circuit 100 through a gland to a load Rl based on the detecting signal from the detecting circuit 60, and the circuit 90 works to suppress an unnecessary charge to a power source side. Thus, the power loss at the time of no signal can be decreased, and simultaneously, the direct current amplification can be executed.

Title: Laminated core with gap for transformer
Inventor: MINAMITANI MASASHI
IPC: H01F27/24
Filed: 1986-12-23
Abstract: PURPOSE:To facilitate a design by using directional silicon steel plates having the same rolling direction as that of legs at the section of a yoke to face the gap of the yoke, and bonding the plates at the oblique faces at 45 deg., thereby preventing a clamp or a local core part from being heated. CONSTITUTION:Legs 11 and a yoke 12 are formed by laminating directional silicon steel plates, the rolling direction of the leg 11 is an elevational direction A, and that of the yoke 12 is a lateral direction B. The part of the leg 12 to face the leg 11 is cut out in a V shape obliquely at 45 deg., and triangular steel plates 12a, 12b having the same direction A as that of the leg 11 are bonded. Thus, the magnetic flux of the leg 11 is expanded at a gap 14, but focused at the plates 12a, 12b, bent perpendicularly at oblique faces 16, 17, and intro duced smoothly to the yoke 12. The magnetic flux does not pass a clamp 15 and is not locally concentrated. Thus, it can prevent the clamp and a local core part from being heated, thereby facilitating a design.

Title: Controller for slip of driving wheel of vehicle
Inventor: TSUBOI MASAAKI
IPC: B60G17/015
Filed: 1996-11-01
Abstract: PROBLEM TO BE SOLVED: To reduce a slip of driving wheels while reducing possibilities that an occupant of a vehicle feels a sense of incongruity. SOLUTION: Slip ratios Sl, Sr of right and left driving wheels are calculated (S10 to 30), whether the slip ratios exceed the reference value Sc or not is judged (S40, 50). When the slip ratios exceed the reference value Sc, the height of the driving wheels is decreased and the height of driven wheels is increased (S90). When the slip ratios exceed the reference value even if the height of the driving wheels is decreased to the prescribed value or less and the height of the driven wheels is increased to the prescribed value or more, the height of the driving wheels is increased by the relative high increase ratio so that supporting load of the driving wheels may be higher than supporting load at the time that height has the specified value, and the height of the driven wheels is reduced (S50 to 160) by the relative high decrease ratio.

This layer 5 consists of the patterns formed of the arrangement of rhombic shapes or rectangular shapes having some area in the rough surface parts or the milky white parts 6. The patterns are arranged at a specified pitch; in addition, the patterns are so formed that the sizes thereof are smaller and the arranging density thereof is smaller the furtherer from the light source 1. The patterns can be formed to the smaller sizes and the smaller inter-pattern pitch and the deposited layers can be formed thinner by using the hot stamping to transfer the printed patterns by pressing a transparent base material, such as acrylic resin, with a heated mold from the surface to be printed of this material. The good reproduction accuracy of the patterns is, therefore, obtd. and the brightness distribution is improved.

Title: Ultrasonic flowmeter
Inventor: MIYAMOTO AKIO
IPC: G01F1/66
Filed: 1993-12-09
Abstract: PURPOSE:To detect abnormal propagation of ultrasonic wave due to mixing of bubble or foreign matter and to continue emergency measurement based on the detection of abnormality. CONSTITUTION:An abnormality detecting circuit 8 detects occurrence of an abnormality in the propagation of ultrasonic wave by two systems. In the first system, forward and rearward receiving waves are delivered from a transmitting/receiving circuit 2 and the abnormality is detected based on the fact that the peak value of time detecting wave is within a set level constantly during a set time interval. In the second system, the abnormality is detected based on the fact that the fluctuation of time difference delivered from a time difference detecting circuit 6 exceeds a set level within a set time interval. A control section 5 makes a switching from a normal correction signal corresponding to normal state to an emergency correction signal corresponding to abnormal state based on an abnormality detection signal delivered from the abnormality detecting circuit 8. A receiving wave correcting circuit 3 amplifies a receiving signal, having level lowered by reflection or damping due to bubbles or foreign matters, based on the emergency correction signal so that emergency measurement of flow rate can be made.
