Title: Tape guide device
Inventor: HASHIMOTO NAOKI
IPC: G11B15/665
Filed: 1986-02-20
Abstract: PURPOSE:To attain miniaturization by turning a tape guide around a turning fulcrum and contacting the tape guide while being turned around a cassette cover when a cassette is loaded to arrange a rotary cylinder and the cassette closely. CONSTITUTION:When the cassette 1a is pushed down from the 1st position, a cover 1f is brought into contact with a cassette opener and then opened. In this case, the cover 1f is in contact with the tape guide 40, which is driven counterclockwise around a fulcrum 42 while elongating a tensile spring 41. When the cassette 1a is further pressed down, the tape guide 40 enters the inside of the cover 1f and then between the cover 1f and a tape 1t. In depressing further the cassette 1a from the state above, the cover 1f is driven by the cassette opener and moved in the approaching direction to the fulcrum 42 and finally is detached from the tape guide 40 completely. In this case, the tape 1t is guided along the guide face of the tape guide 40 and placed at a prescribed position without being in contact with the rotary cylinder.

Title: Diagnostic device for osteoporosis
Inventor: ISHII TETSUYA
IPC: A61B8/00
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To easily perform highly reliable diagnosis by measuring the elasticity of bones with accuracy. SOLUTION: Data obtained in advance through accurate measurement of the density of a predetermined cortical bone of an examinee by an X-ray CT device and the like is inputted by using a keyboard 3. Next, ultrasonic pulses are repeatedly emitted toward the cortical bone where the bone density of the examinee was measured, and echoes from the cortical bone are received. The signals received are converted into digital echo signals by an A/D converter 8, their echo levels being detected by a CPU 11. The CPU 11 extracts a maximum echo level from the echo levels extracted during a measuring period, and calculates the acoustic impedance of the cortical bone on the basis of the maximum echo level. From the calculated acoustic impedance of the bone and the input density of the cortical bone, the elasticity of the cortical bone of the examinee is calculated.  The elasticity of the cortical bone serves as an important standard to show the resistance to fracture of the bone and is therefore effective in performing reliable diagnosis on the osteoporosis.

Abstract: PURPOSE: To easily drive H-type steel sheet piles into the ground containing many large stones. CONSTITUTION: To drive H-type steel sheet piles 5 continuously in a line, end portions 6 are mounted on the lower ends of the H-type steel sheet piles 5. Each end portion 6 is a four-sided body consisting of an upper surface connected to the H-type steel sheet pile 5, a vertical back face 6b, a front inclined surface 6c, a left inclined surface 6d, and a right inclined surface. If the end portion 6 comes into contact with a stone S when each H-type steel sheet pile is driven, the stone S is forced out by the front inclined surface 6c to deviate from the driving direction. When forcing the stone S out, the end portion 6 is pressed in the direction opposite to the stone S and is restrained by the previously driven H-type steel sheet pile 5. Therefore, the H-type sheet steel piles can easily be driven straight into the ground containing many large stones.

Title: Signal level clamping circuit

IPC: H04N5/18
Filed: 1987-02-20
Abstract: PURPOSE:To remove an offset voltage, including the one produced from a signal processing circuit itself, and to set a highly precise signal level setting by giving a feedback to the output signal of the signal processing circuit, after converting it to a digital signal, and clamping the voltage level of the input signal of the signal processing circuit. CONSTITUTION:A clamping voltage is adjusted based on a digital voltage quantity, outputted from the signal processing circuit to process the input signal. Namely, the digital quantity of the voltage, outputted by the signal processing circuit, and a digital code, corresponding to the target reference voltage level are compared by a comparator 11, and the digital quantity corresponding to their difference voltage is outputted. Next, the digital quantity is converted into an analog quantity V10 by a D/A converter 12, and further, the analog voltage quantity V10 is added or subtracted during the specified period of the input signal. As the result of the addition or the subtraction of the first time, when the difference voltage appears still in the output of the comparator 11, the clamp voltage quantity V8 is corrected by giving the further feedback. Thus, the feedback is given until the difference voltage comes to zero substantially. Thus, the setting of the highly precise clamp voltage is made possible.
