Title: Method and device for satellite broadcast reception
Inventor: NEZU YASUHIKO
IPC: H04N7/20
Filed: 1989-04-11
Abstract: PURPOSE:To realize high accuracy and high response performance of a BS tuner by mixing a 2nd IF signal with an oscillated signal from a stable oscillation circuit for down-convert, applying frequency conversion to the mixed signal, counting the result, detecting a deviation of the 2nd IF signal. CONSTITUTION:When the user selects a received channel, a microcomputer 32 outputs a standard frequency division ratio for reception to a PLL circuit 30. After the reception, when a discrimination circuit 92 uses synchronizing signal to discriminate the mode to be the NTS reception mode, an output circuit 98 outputs a clear signal and a gate signal to a counter circuit 46 and outputs a vertical synchronizing signal to the microcomputer 32. The microcomputer 32 reads a count of the circuit 46 and averages it and compares the result with a reference data. Then the deviation or the 2nd IF signal is detected, the frequency division ratio of the circuit 30 is made variable to apply AFC operation. After the channel selection, the signal outputted from a terminal 72a is a MUSE signal by the discrimination of a MUSE decoder, a keyed AFC pulse signal P is inputted from a terminal 74 of the BS tuner 16 and when the circuit 92 discriminates the MUSE reception mode, the microcomputer 32 applies AFC operation.

Title: Fuel cell system
Inventor: OKUMURA MINORU
IPC: H01M8/04
Filed: 1985-04-30
Abstract: PURPOSE:To reliably prevent choking of a cooling tube by inhibiting the production of a clad by installing a bypass pipe for introducing part of pure water containing a high concentration of dissolved oxygen which has not yet undergone degassing into a fuel-cell-cooling system and using a metallic tube such as a stainless steel tube as the cooling tube. CONSTITUTION:The concentration of oxygen dissolved in the cooling water of the fuel-cell-cooling system is maintained at a constant level (20PPb-200PPb) by supplying pure water containing a high concentration of dissolved oxygen which has not yet undergone degassing into the cooling water through a bypass pipe 11 and a control valve 12 according to the flow rate of the cooling water. As the result, a hematite film (Fe2O3) is formed on the surface of a carbon steel tube used as the pipe of the fuel-cell-cooling system and the hematite film inhibits the production of a clad thereby preventing any choking of the cooling tube. Besides, since a stainless steel tube is used as the cooling tube, there is no possibility that the cooling tube is corroded even when the concentration of dissolved oxygen is increased to 10PPb or higher.

Title: Apparatus for detecting acceleration of car body
Inventor: HASHIMOTO YOSHIKAZU
IPC: G01P15/16
Filed: 1988-04-15
Abstract: PURPOSE:To accurately detect the acceleration of a car body without receiving the effect of gravitational acceleration, by detecting the acceleration of the car body from the degree of extensibility of a suspension. CONSTITUTION:Position sensors S1 to S4 detect the quantities of extensibility of the suspensions 1 to 4 of front and rear left and right wheels. The degrees of extensibility from an equilibrium pint of these suspensions 1 to 4 are calculated by holding circuits 11-14 and differential circuits 2 to 24. In order to calculate the before and behind pitching angle of a car body from said degrees of extensibility, the difference between the degrees of extensibility on the front and rear wheel sides is calculated by a differential circuit 31 with respect to the righthand to be converted to a pitching angle deltaR using a wheel base length by a circuit 41. Even when respect to the lefthand, the difference of the degrees of extensibility on the front and rear wheel sides is calculated by a differential circuit 32 to be converted to a pitching angle deltaL by a circuit 42. Since the difference between these angles deltaR, deltaL is caused by the left-and-right inclination of the car body 5, an arithmetic mean is taken by a circuit 51 in order to remove said difference. The acceleration of the car body is calculated from the obtained average value delta. At this time, correction is applied corresponding to the characteristics of the suspensions 1 to 4 by a circuit 61.
