Title: 3-axis accelerometer calibration jig
Inventor: KOMURA HIDETOMO
IPC: G01P15/18
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To rapidly perform calibration work by providing an accelerometer attaching surface which forms a specified angle for the flat plane orthogonal to the gravitational acceleration direction to allow easier attaching work of an accelerometer to a calibration jig. SOLUTION: An attaching surface 2b, forming an angle tan<-1> (2<1/2> ) (about 54.74 deg.) against a flat plane 1a orthogonal to the gravitational acceleration direction, is provided to a block 2. On the attaching surface 2b, a three axis accelerometer 4 is so attached that gravitrational acceleration equal to X-direction sensitive axis and Y-direction sensitive axis of the accelerometer 4 acts. Then, on each X, Y and Z axis acceleration sensor, the identical acceleration component (about 57.4% of gravitational acceleration G) due to the gravitational acceleration G acts. Thus, by adjusting a gain of an amplifier, a display, etc., with a calibration device so that the output voltage of each axis acceleration sensor displays the identical value, sensitivity calibration can be performed by attaching a calibration jig to the accelerometer 4 only once.

Abstract: PURPOSE: To contrive to improve the repetition durability of printing and erasing without being influenced by ambient atmosphere by a method wherein a phase separation structure having the condition that the peak range of the structural period of the phase separation is specified and, at the same time, the scattering strength of the peak is checked to a specified percentage or less is given to an organic low molecular substance. CONSTITUTION: This reversible heat sensitive recording material is formed by providing a heat sensitive recording layer consisting of an organic low molecular substance, the transparency of which reversibly changes in dependence on the temperature, and a resin matrix on a support. In addition, the organic low molecular substance is turned into a phase separation structure dispersed in the resin matrix under the condition that the range of the peak in the structural period of the phase separation is set to be 1.5-1.7μm. At the same time, the scattering strength within the domain ranging from the peak +0.25μm to the peak -0.25μm is checked to the peak lowered by 15% or more.  Due to the phase separation structure between the organic low molecular substance and the resin matrix, in-particle separation can be prevented from developing and the repetition durability of printing and erasing can be improved hardly influenced by various ambient atmospheres. Further, the fluctuation in cloudy sensitivity can also be improved.

Title: Intake device for internal combustion engine
Inventor: KANEKO MAKOTO
IPC: F02B31/02
Filed: 1987-03-12
Abstract: PURPOSE:To improve the charging efficiency of intake air by providing many recess parts on the inside surface of a downstream end of an intake pipe and a bending part on the inside surface of the peripheral wall of an intake port respectively, and thereby generating a static vortex in each recess part to reduce the intake resistance of the intake air. CONSTITUTION:An intake device is composed of an intake pipe 1, a siamese port 2 formed of intake ports 3 communicating with the intake pipe 1, and intake valves 5 provided in the intake ports 3. In this case, the downstream end 1a of the intake pipe 1 and a bending part 10a on the peripheral wall 10 of the siamese port 2 are formed with many recess parts 11 respectively, for instance in a zigzag shape. A mixture flow along the pipe wall of the intake pipe 1 is therefore caused to flow into each recess part 11 to generate a static vortex C there. Thus the mixture flow is guided along the static vortex to prevent its separation, and drawn into the intake valve 5 in a laminar flow. Consequently, since a mixture flow passage is never throttled, the intake air can be effectively charged even through the intake pipe 1 formed into small bore.
