Title: Fan for vehicle
Inventor: KUROKI SHINYA
IPC: F01P11/10
Filed: 1989-01-21
Abstract: PURPOSE:To attempt to reduce noise as well as to enhance the cooing efficiency by arranging that the shape of a sound is properly changed in conformity with the difference in the condition of a draught system at the time of high pressure loss or low pressure loss of an axial flow fan. CONSTITUTION:At the idling time of a high draught system, a working ring 20 is placed at the position a little to the front, and the boundary line 2c of an air conducting part 17 and a releasing part 16 is placed at the adjacent position of the front edge 4a of an oil flow fan 4 to make the forward open angle theta of the releasing part 16 large. On that account, the inflow air along the release part 16 from the blade tip of the fan 4 to the conducting part 17 is decreased, and the turbulence generated at the blade tip of the fan is removed by the leading-edge of the conducting part 17 and the noise generation is reduced. As the loss in the air blasting is decreased when the turbulence and the centrifugal flow at the conducting part 17 are further removed, the cooling efficiency of a radiator 1 is enhanced. Next, since the ring 20 is placed a little to the center when changed to the time of low draught system, and the position of the boundary line 2c is separated from the fan 4 to the extent of distance L making the angle theta small, the turbulence at the blade tip of the fan 4 is made small and the reduction of noise generation and enhancement of cooling efficiency become possible.

Title: Clamping circuit and synchronizing separator circuit
Inventor: HIRAO YOSHICHIKA
IPC: H04N5/08
Filed: 1995-01-31
Abstract: PURPOSE: To perform exact clamping. CONSTITUTION: Video signals are supplied from an input terminal 12 through a capacitor C1 and a transistor T11 to the transistor T12. The tip potential of synchronizing signals included in the video signals and a reference voltage VREF are compared in a differential pair 14. When the tip potential is lower, the base current of the transistor T16 is made to flow, the collector current of the transistor T16 charges the capacitor C1 and the base potential of the transistor T11 rises. Inversely, when the tip potential is low, since the transistor T16 is turned off and the capacitor C1 is discharged, the potential of the transistor T11 is lowered. By such operations, the clamping is performed so as to make the tip potential of the synchronizing signals equal to the VREF.  In this case, since the gain of a negative feedback loop provided with the transistor T16 logically becomes infinite, negative feedback is performed to the differential pair 14 so as to almost completely compensate the difference of the two inputs of the differential pair 14 and offsets are hardly generated.

Title: Distributing method for draft percentage in continuous rolling work
Inventor: KODERA YOSHIKAZU
IPC: B21B37/24
Filed: 1980-02-08
Abstract: PURPOSE: To stably, accurately carry out the uninterruptedly thickness changeable rolling work for a strip, by making the changing rate of draft percentage of the upstream side rolling stand larger than the changing rate of draft percentage of the downstream side rolling stand, at changing the thickness of the same strip undergoing a continuous rolling work.  
     CONSTITUTION: At changing the thickness of a strip undergoing a continuous rolling work, the variation of draft percentage of each rolling stand is uniformly distributed according to the equation so as to generate the same amount of turbulence in  the mass flow before and after the thickness change between every couple of rolling stands. Hereby, the distribution of draft percentage to each rolling stand after changing the sheet thickness is made largely part from that before changing the thickness, on the upstream side of the strip; whereas, it is made an associated value on the downstream side. As a result, an effect to further shorten the off-gauge length of the strip, other than a great improvement of the breadth accuracy, the shape, the operatability and the passableness of the strip, is developed during the uninterruptedly thickness changing rolling work.
