Title: Digital servo speed detecting system
Inventor: UENO TAKAHISA
IPC: G11B21/08
Filed: 1988-09-10
Abstract: PURPOSE:To finely calculate the moving speed of a magnetic head by reading the contents of a counter for several times, respectively deciding that the movement is within a track when the contents are the same and that it is over the track boundary when they are different, and calculating an intra-track position from a digital position error signal. CONSTITUTION:The counted contents of a counter 4 to count the track boundary detecting pulse from a demodulating circuit 3 are read for several times by a processor 6, the position error signal from the demodulating circuit 3 is converted by an AD converter 5, and read by the processor 6. The counted contents are compared, when they are the same, it is decided that the movement is within the same track, the track position is discriminated from the counted contents, the intra-track position is discriminated by the digital position error signal, and made into a present position. When they are inconsistent, it is decided that a magnetic head 2 moves over the track boundary, an intra-track maximum position or one track portion is added to the track position, and made into the present position. Thus, even when the magnetic head 2 is moved at high speed, the moving speed can be accurately detected.

Title: Composite probe for fluid speed measurement
Inventor: SATO HIROSHI
IPC: G01F1/68
Filed: 1986-09-24
Abstract: PURPOSE:To measure the direction and speed of fluid in all directions in front of a base by providing plural sensors which have constant output characteristics to the fluid arriving from within a constant angle range, allowing a probe in the fluid to measure the fluid speed nondirectionally in a stationary state, and rotating it around a longitudinal beam as an axis. CONSTITUTION:A cross beam 1 is constituted by combining the longitudinal beam 8 and a lateral beam 9 in a cross shape, one end of the longitudinal beam 8 is fitted onto a base 4, and the sensors 5a-5c whose outputs are constant within the constant range of the angle to the flow of the fluid, but decrease outside the constant angle range as the angle increases or decreases are fixed to three end parts of the beam 1, thereby forming three signal-body probes. Then, a voltage is applied to the sensors 5a-5c and a resistance value which varies according to temperature variation due to the contacting with the fluid is converted by a current, voltage, or electric power, thereby measuring the speed and direction of the fluid. Further, the beam 1 is rotated around the beam 8 as the axis to find the flow direction of the fluid from output characteristics and rotational angles of sensors which are within the constant angle range of the angle to the flow of the fluid.

Title: Delivery unit
Inventor: MORI KUNINORI
IPC: A47K3/00
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To eliminate a temperature difference between upper and lower levels, or mix different types of liquids for obtaining a uniform liquid via the use of the existing liquid tank-related facility by sinking a delivery unit to the bottom of a liquid tank, externally supplying the delivery unit with a liquid having higher temperature than a liquid in the tank, or supplying the delivery unit with a liquid having smaller specific gravity, when a mixture of two liquids is desired. SOLUTION: Regarding a bathtub or the like, hot water, when fed from a shower head mounting port 3 to a delivery unit sunken to a bottom comes out of porous delivery ports 4 and rises. This hot water subsequently comes out of small holes on the surface of the delivery unit. When the temperature rise of water in the bathtub is desired for bathing, with the delivery unit laid on the bottom thereof, an accessory shower head is plugged into the shower head mounting port 3 of a base, and a shower cock is opened to feed hot water. Also, the specific gravity of the material of the delivery unit is made higher than the specific gravity of water, so as to sink the delivery unit to a water bottom. As a result, processes for mixing, agitation or the like can be eliminated, when uniform temperature in a liquid tank or a mixture of two liquids having slightly different specific gravity is desired.

Title: Power source circuit of dead weight meter for truck
Inventor: UCHIYAMA SHINKICHI
IPC: G01G19/12
Filed: 1982-12-24
Abstract: PURPOSE:To prevent the breakdown of an element, which controls an output transistor that is used in the power source circuit of a dead weight meter for a truck, due to a surge voltage, by connecting the power source terminal of the element, which controls the output transisor of a power source stabilizing circuit, and the output terminal of the power source stabilizing circuit. CONSTITUTION:A power source terminal 44 of an operation amplifier 42 is connected to the emitter of an output transistor 41, i.e., the output terminal of a power source stabilizing circuit 40. A Zener diode 47 and a resistor 48 are used to apply a voltage, which is obtained by increasing the output voltage of the operation amplifier 42 by a specified amount, to the emitter of the transistor 41. The output voltage of the operation amplifier 42 is required because it is lower than the voltage, which is required to control the transistor 41. Therefore, the Zener diode 47 can be substituted by a resistor. Even though a surge voltage is generated, the surge voltage does not reach the parts after the collector of the output transistor 41. Therefore, the operation amplifier is not broken down by the surge voltage.

Title: Press forming device
Inventor: TANAKA SHIGETO
IPC: B30B15/30
Filed: 1994-09-21
Abstract: PURPOSE: To enable the use of many small forming dies by providing a work space changing means by which a work space is changed in accordance with the work forming space required by the forming die of the next process in the middle of many processes. CONSTITUTION: Two pieces of work W, W are worked side by side. In a flange forming process Sf, a work W is worked with a space between both works W, W maintained at a normal space P1. In the next process, a cam forming process Sc, since a larger space is required between both works W, W, working is performed with that space widened to P2 by a work space changing means. Without the change of the work space, an entire process need to be performed with a wide space, requiring a large-sized forming dies. Additionally, wastes between works will be increased in a blank, increasing loss in materials. Thus, such absurdity may be prevented.
