Title: Impulsive acceleration tester
Inventor: DOUKE MITSUTSUNE
IPC: G01N3/31
Filed: 1989-03-10
Abstract: PURPOSE:To obtain a desired shock response spectrum (SRS) characteristic by making plural arms having hammers in front ends different in shock characteristic from one another and rotating these arms in order or simultaneously to strike each hammer against a sample body. CONSTITUTION:When a supporting pin 8 is released in the direction of an arrow B or C, arms 5A to 5C are rotated by the weight of respective hammers 7A to 7C; and when they are rotated at 180 deg., hammers collide with the lower face of a test plate 2 to impress the impulsive acceleration to a sample body 1. When the pin 8 is horizontally moved to release arms 5A to 5C in order at this time, arms are rotated in order and respective hammers 7A to 7C successively collide with the plate 2. Thus, the momentary shock is suppressed in comparison with simultaneous collision of hammers 7A to 7C, and projection of the level is prevented to obtain a characteristic approximating the desired SRS.

Filed: 1988-03-15
Abstract: PURPOSE:To obtain an inexpensive display device which generates no heat by coloring light which is projected by a fluorescent lamp through a rotary filter, passing the light through an optical fiber group, and making a display on a display board. CONSTITUTION:The fluorescent lamp 12 as a light source illuminates and a motor for driving the rotary filter rotates to rotate a belt 21 in a longitudinal direction around the fluorescent lamp 12.

Title: Pipe with inserting hole
Inventor: MIKAMI TADAO
IPC: G01F1/32
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To improve the withstand pressure characteristic of a pipe with inserting hole by providing a stress concentration relieving section having a flat or curved surface inside a pipe at the intersection of the pipe and inserting hole. SOLUTION: A Karman's vortex flowmeter is constituted in such a way that a fluid flows through a pipe 10 and a cylindrical nozzle 11 is provided perpendicularly to the pipe 10. A vortex generating body 12 is perpendicularly inserted into the pipe 10 through an inserting hole 31 with a clearance between the body 12 and nozzle 11 and has a columnar shape having a trapezoidal cross section. A stress concentration relieving section 41 is provided inside the pipe 10 at the intersection of the pipe 10 and hole 31 to relieve stress concentration and has a flat or curved surface. When the section 41 has the flat surface, the section 41 is prolonged along the center axis of the pipe 10.  Even when the fluid applies a high pressure to the pipe 10, therefore, the stress concentration caused by the hole 31 can be avoided with little reduction in flow rate of the fluid without enlarging the external size of the pipe 10. In addition, an inexpensive pipe with inserting hole can be obtained, because the pipe 10 can be manufactured easily.

Title: Rolling bearing
Inventor: HIBI KENJI
IPC: F16C33/62
Filed: 1991-02-28
Abstract: PURPOSE:To provide a longer rolling fatigue life and higher function in rolling bearing used at a high temperature and high speed. CONSTITUTION:At least either of an outer ring or an inner ring where a ceramic rolling element is incorporated is formed of powder high speed steel of HRC 65 or more in hardness. In the powder high speed steel, there is not giant carbide which effects an adverse influence on the rolling fatigue life of a bearing in its structure, and heat ray expansion coefficient is next to iron which is a material for forming a housing. Therefore, a bearing provided with a bearing ring made of powder high speed steel not only has good service life characteristic even at a high temperature and high speed, but also has no fear of generating creep between the outer ring and the housing due to a temperature change, and increased fitting allowance between the inner ring and a shaft.

IPC: H04L7/04
Filed: 1989-03-13
Abstract: PURPOSE:To connect the terminal equipment of a start-stop system transmission means to a synchronous type MODEM without the revision of the equipment by receiving a start-stop system transmission data in a sampling clock and converting the data into a synchronous type transmission data synchronously with the selected transmission clock. CONSTITUTION:A start-stop synchronization conversion means 15 receives a start-stop system transmission data in response to a sampling clock outputted from a clock generating means 11. Moreover, the means 15 converts the start- stop system transmission data into the synchronous transmission data in response to either the transmission clock outputted from the clock generating means 11 or the transmission clock supplied from a synchronous MODEM and outputs the result. Thus, the processing of the transmission clock between the terminal equipment of the start-stop system transmission protocol and the synchronous MODEM and the conversion from the start-stop system transmission data into the synchronous transmission data are attained and both the equipments are connected without any revising.

Abstract: PURPOSE:To shorten the time for writing a data and to promote the reliability by writing the same data in an alternate track adjacent to a track in which a data error is generated at the time of writing. CONSTITUTION:A track 12 for writing a data and an alternate track 14 for this track are alternately disposed on an optical disk medium 11(3), and when a data error is generated at the time of writing, the same data as this is written in an alternate track 14 for the track 12 concerned.

Abstract: PURPOSE: To obtain a stable electrode with good reproducibility without failing to crystallize a Gap layer, by adding a thin group V element to the surface of the GaP layer when forming the electrode on the GaP layer constituting a light-emitting diode.  
     CONSTITUTION: On N-type GaP substrate 11, P-type GaP layer 12 is formed by liquid-crystal epitaxial growth to constitute a red light emitting diode, and group V element ions such as As are injected into its surface to form thin As element injection region 14.

Then, a heat treatment is carried out in an Ar atmosphere of 500°C for about twenty minutes and the layer-11b side is mounted on header 15. Consequently, the light-emission efficiency increases by approximately 10% in comparison with an ordinary diode and the contact resistance of the electrodes decreases down to 5× 10 -5 Ωcm to the contrary.

Title: Measuring apparatus of liquid
Inventor: KUMAGAI KUNIO
IPC: G01F13/00
Filed: 1981-04-23
Abstract: PURPOSE:To prevent lowering of accuracy in case of carrying out measurement of a small quantity in a liquid measuring apparatus having a wide measuring range, by carrying out (n) times measurement of necessary quantity at one time and obtaining the necessary quantity by dividing into (n) equality. CONSTITUTION:For example, two times quantity of necessary measuring value of a liquid is measured by a flowmeter 4 and the liquid is stored in a measuring vessel 6. Valves 7 and 13 are opened after the measurement is finished. At this time, valves 15, 16 are shut. Already measured liquid is charged into a measuring vessel 10 for dividing into equal parts from the vessel 6 by opening the valve  7 and said liquid is divided in the measuring vessels 10, 11 equally by a connecting pipe 12. After that, each vessel 10, 11 becomes independent by shutting  the valve 13 and the division into equal parts is accomplished. Thus, lowering  of accuracy in case of carrying out measurement of a small quantity is prevented in a liquid measuring apparatus having a wide measuring range, because the measurement of two times necessary quantity is carried out at one time and the  necessary quantity is obtained by dividing into two equal parts.
