Title: Negative pressure slider
Inventor: WATANABE MAKOTO
IPC: G11B21/21
Filed: 1988-02-19
Abstract: PURPOSE:To prevent occurring negative pressure from being much changed and to enable a head slider to keep stable flotation even when the position of the head slider is changed in some degree by providing independent plural negative pressure generation areas on the flotation surface of the slider along a relative movement direction for a recording medium. CONSTITUTION:The independent negative pressure generation grooves 21-23 and 31-33 are respectively formed in a line state on either side to the back half of two sliders as the negative pressure generation area and all of them are made along the relative movement direction of the medium and the head slider 1. As the plural negative pressure generation grooves are formed on the slider flotation surface having a cylinder state curved surface in that way, suction force generated by the negative pressure of each groove is changed according to the attack angle of the slider and negative pressure suction force which generally occurs is scarcely changed even when the attack angle of the slider is changed. Thus, even when the position of the head slider is changed in some degree, the occurring negative pressure force is not much changed and the stable flotation can be kept.

Filed: 1980-03-24
Abstract: PURPOSE: To improve a fuel consumption rate while preventing occurrence of a knocking action in an engine, by setting to form its cylinders partially in a high compression ratio so that an intake manifold for said cylinders of high compression ratio may be throttled.  
     CONSTITUTION: The second throttle valve 18, being in a fully open state in an operational range of partial load, can allow mixture to equally enter all cylinders 1W 4 to obtain output from their combustion. Here the third and fourth cylinders 3, 4, being formed to a higher compression ratio as compared with the first and second cylinders 1, 2, can improve a fuel comsumption rate by that amount. While the second throttle valve 18 displays its throttling action in a high load range to cause the lower charging efficiency of mixture in spite of the high compression ratio in the cylinders 3, 4, thus substantial pressure of compression can not be increased to prevent occurrence of a knocking action.

Abstract: PURPOSE:To obtain a reproduced picture of the better density by obtaining the different reference voltage levels of A/D conversion for a character original part and a photo original part respectively via a preparatory scan and carrying out a primary scan based on the obtained reference voltage value. CONSTITUTION:A binary area density data memory 28 and a halftone area density data memory 29 store the read modes in response to the minor areas. A density control data computing means 26 calculates the picture density of each read mode based on the picture data obtained via a preparatory scan and the data on both memories 28 and 29 and then calculates the optimum A/D reference voltage value of each read mode based on the calculated picture density. Then a read control means 26 reads pictures based on the calculated A/D reference voltage value and the data on both memories 28 and 29. In an automatic density control mode, the pictures of both the character and photo original parts are read based on the different reference voltage levels of A/D conversion for both original parts. Thus the optimum density control is possible with each area and a reproduced picture is obtained with better density.

Abstract: PURPOSE:To obtain the noncontacting speedometer for a railroad car which measures an accurate speed by providing a frequency circuit which tracks the 1st zero point of the correlation function of a Doppler signal obtained by a Doppler device for a microwave. CONSTITUTION:The microwave Doppler device 1 and a horn antenna 2 are fitted to the lower part of the car body 3 at an angle theta to the ground 4. When the car body 3 runs at a relative speed (v) to the ground 4, a Doppler signal is generated at the output terminal of the device 1. This Doppler signal is amplified 5 and passed through a band-pass filter 6 to increase its S/N ratio. The center frequency Doppler signal X(t) after being passed through the filter 6 is measured by a center frequency circuit measuring 7 and converted into a speed, which is displayed 8. The circuit 7 traces the 1st zero point of the autocorrelation function by using a digital cirlcuit. Therefore, this contactless speedometer measures the accurate speed even if wheels slip on rails.
