Title: Displaying method for observer relatively moving at high speed and device therefor
Inventor: KOZUTSUMI MICHIRO
IPC: G09F9/30
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To provide a device capable of displaying/recognizing an image substantially in a stationary state even when a moving body and a display device have the relation of the relative movement at high speed. SOLUTION: One dimensional pixels S1, S2,... are successively displayed in a time series with a time interval according to the relative velocity by a display device 10 for displaying one dimensional pixels S1, S2,... of an image perpendicular to the moving direction and, thus, two-dimensional image S is constituted. By installing plural one-dimensional pixel display devices 10, 10,... in the moving direction separated by a fixed interval P apart and repeatedly displaying the two-dimensional image S, a continuous picture is obtained and a moving picture is obtained by successively displaying different images. By means of a display device moving at the relative speed as quick as lightning viewing from an observer, a stationary image is seen.

Title: Manufacture of piezo-electric ceramic
Inventor: NARITA TOSHIMI
IPC: H01L41/39
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To raise grinding efficiency and improve production efficiency by grinding and grading mixture powder before calcinating until its grain diameter becomes undersize of JIS standards sieve whose opening of mesh is a specified value and thereafter making it react by calcinating. SOLUTION: After raw material of piezo-electric ceramic of PbTiO3 -PbZrO2 - Pb(Sn1/3 Sb2/3 )O3 system is combined, it is subjected to enough wet mixing. After slurry obtained in the wet mixing is dehydrated and dried, it is ground and sized until particles are under the JIS standard sieve of opening of 9.52mm by a sizer. Thereafter, it is subjected to calcinating reaction. The calcinated raw material is subjected to wet grinding for a fixed time by pure water of the same mass as a raw material and ZrO2 ball whose mass is 2.5 times a raw material. The ground grain diameter of the obtained ground raw material becomes small in a short time and unground grain remaining on the sieve reduces remarkably when slurry after grinding treatment is subjected to mesh pass.

Title: Brake controller for electric automobile
Inventor: KADOSAKI SHIROU
IPC: B60T13/58
Filed: 1991-12-24
Abstract: PURPOSE:To enhance brake feeling in response to the rising of liquid consumption of wheel cylinder. CONSTITUTION:Pressure of master cylinder is applied on a wheel cylinder 26 upto a wheel cylinder pressure Po at which rising of liquid consumption terminates, and a stroke simulator 38 simulates liquid consumption of the wheel cylinder 26 during an interval from cylinder pressure Po to Po+DELTAPr. At a point of cylinder pressure Po+DELTAPr, master cylinder pressure for opening a passage is applied again.

Abstract: PROBLEM TO BE SOLVED: To improve the illumination of a projected picture by bringing the shape of a luminous intensity distribution characteristic close to that of the display panel, thereby reducing the quantity of ineffective light reaching a part other than a display panel. SOLUTION: This light source for a projector 1 is formed so that a reflection mirror 3 is formed to such a shape that an ellipse appears in a section passing through the optical center line Z of the reflection mirror 3 and is formed as the ellipse whose long and short diameter directions are matched with the longitudinal and lateral directions of the display panel 11 in the shape when the reflection mirror 3 is viewed from the front side, and the second focus P2W of the ellipse appearing in the section on the side of the long diameter W is in a position further than the second focus P2H of the ellipse on the side of the short diameter H. Therefore, the shape of the luminous intensity distribution characteristic is brought close to that of the display panel. Thus, the quantity of the ineffective light reaching the part other than the display panel can be reduced.

Title: City water direct-coupled fire-extinguishing equipment and flow water detecting valve
Inventor: KUNIKAWA AKITERU
IPC: A62C35/58
Filed: 1989-12-28
Abstract: PURPOSE:To sufficiently supply fire-extinguishing water even if a fire is generated in the course of feeding water to a bathtub, etc., by providing a fire-extinguishing branch pipe connected to a water main through a flow water detecting valve, a city water branch pipe connected through a changeover valve to the water main of the upstream of the flow water detecting valve concerned, and a control part of the changeover valve connected to the flow water detecting valve. CONSTITUTION:A closed type sprinkler head 15 is connected to a fire-extinguishing branch pipe 16, a flow water detecting valve 3 is closed, and also, a changeover valve 22 is opened. In such a state, water of a water main 1 flows to only a city water branch pipe 21, therefore, when a faucet 20 is opened, water comes out. When the sprinkler head 15 operates due to generation of a fire, etc., pressure in the fire- extinguishing branch pipe 16 becomes lower than that in the water main 1, therefore, the flow water detecting valve 3 is opened, and also, a control part 23 of the changeover valve 22 operates and closes the changeover valve 22. Therefore, feed water into the city water branch pipe 21 is cut off, and water from the water main 1 is all supplied into the fire-extinguishing branch pipe 16, and exhausted from the sprinkler head 15.

A stopper 11 protrudes from the lower part of a damper cover 10, a stopper guide 12 is provided on the upper part of the damper 6. A position A where the damper 6 is turned up clockwise is a position where the opening areas of an upstream hole 6a, a downstream hole 6b become small as a reference position. The damper 6 is brought to the reference position at the time of starting an operation. As the damper 6 is moved counterclockwise from the reference position, the opening area of the hole 6a, 6b is linearly increased. When the damper 6 is rotated to the maximum, the stopper 11 is disposed at the position B of the guide 12. In this case, the opening area of the hole 6a, 6b is maximum. The position of the damper 6, i.e., burning air amount can be easily and accurately regulated only by the number of output pulses of a stepping motor.
