Title: Hydraulic shock absorber
Inventor: JO TADASHI
IPC: B60G17/08
Filed: 1986-12-16
Abstract: PURPOSE:To form a device in small size low decreasing its cost and realizing an anti-roll function, by providing a selector valve which is opened and closed by a supply pressure from the outside relieving, when it is closed, oil in an upper chamber in a cylinder to a bottom chamber by an accumulator formed in a shock absorber main unit. CONSTITUTION:A selector valve 30 and a damping force generating part 40 are provided in a base valve part 11, and the valve functions so as to be closed if an outside supply pressure P is applied. While a cover cap 25 forms an accumulator Q as a housing, and the accumulator Q, when an inflow to its oil chamber Q3 of oil in an upper chamber A in a cylinder is allowed by closing the selector valve 30, compresses a gas chamber Q2 preventing an outflow of oil in the upper chamber A in the cylinder. In this way, an extension side oil lock condition is displayed. Accordingly, a device, which is formed in small size enabling its cost to be low reduced, displays a shock absorber function and an anti-roll function improving comfortableness to ride and driving stability.

Title: Perspective image constitution and display device
Inventor: GOTO YOSHIHIRO
IPC: G06T15/08
Filed: 1999-10-21
Abstract: PROBLEM TO BE SOLVED: To reduce the capacity of a memory needed to constitute a perspective image which can have a specific position emphasized and displayed. SOLUTION: A classification memory 2 for recording presence/absence information (or appearance frequency of pixels) on pixels for every CT value is prepared as a linear memory having length corresponding to the number of classifications of the CT values classified according to the CT values. The presence/absence information of the pixels for every CT value on one projection line is recorded in the classification memory 2, product sum operation between the presence/absence information and weight coefficients by the CT values is performed, and according to the arithmetic result, the density value of one pixel is calculated. This classification memory 2 is cleared every time the density of one pixel constituting a perspective image is calculated and used repeatedly to calculate the density value of a next pixel.  Consequently, a three- dimensional memory (classification memory) of screen size multiplied by the number of classifications of the CT values classified corresponding to a conventional CT value need not be prepared to reduce the capacity of the memory which should be mounted.

Abstract: PURPOSE:To satisfactorily make holes of very small diameter, where drill breaking and hole burr are very liable to occur, by making holes after placing a glass epoxy material provided with holes larger than through holes as a mask plate on an inside layer material. CONSTITUTION:Inside layer through holes 7 are first made in a glass epoxy material by the use of information similar to the pattern for making holes in an inside layer material 5 so that a mask plate 3 is formed. Then, a sacrificed plate 6, inside layer material 5 and back plate 4 are stacked up and set in a perforator. Thereafter, the mask plate 3 is placed on them. Then, when holes are made by a very small diameter drill 1, the inside layer through holes 7 are made in the bored positions of the mask plate 3. Thus, the weight of the mask plate 3 prevents the back plate 4 from being drawn up by the dust collection of a pressure hood 2 and it is possible to obtain satisfactory inside layer through holes 7 free from drill breaking and hole burr.

Filed: 1991-10-21
Abstract: PURPOSE:To shorten the temperature measuring time of a constant temperature oven by providing the second detecting-function part, wherein number of times for detecting operation are fewer than that of the first detecting-function part, and a means, which starts the detecting operation with the voltage signal of a memory means when one of the detecting-function parts is started. CONSTITUTION:When the temperature of a constant temperature oven is detected as a voltage signal with a temperature sensor 1, the voltage signal is outputted into one input terminal of a comparator 4 as a voltage value V2, which is to be amplified with an amplifier circuit 3. Meanwhile, the voltage signal having the voltage value V3 is imparted to the other input terminal of the comparator 4 from a CPU 5 through a D/A converter 6, PWM circuit 7 and a low-pass filter 8. As a result, a value '1' is outputted from the comparator 4 when V3<V2. A value '0' is outputted when V3>V2. The CPU 5 detects the output of the comparator 4 and imparts the digital voltage value to the converter 6. When the output of the comparator 4 is changed, it is judged that the voltage, which is imparted to the converter 6, is the measured voltage value.
