Title: Panel light source device
Inventor: KOBAYASHI AKIRA
IPC: F21V13/10
Filed: 1990-05-16
Abstract: PURPOSE:To improve the uneveness of luminance and the reduction of thickness by making the top part of the projecting part of a reflection plate higher than the center position of a light source and setting the distance between the light source and a diffusing plate and the rise bottom part of the projecting part to proper values. CONSTITUTION:A white reflection plate 2 is provided with projecting parts 21 in center parts between light sources 1. Top parts 22 of projecting parts 21 are made higher than center positions of light sources 1 and have a height corresponding to 80% of a distance (d) between light source 1 and a diffusing plate 3. Rise bottom parts 23 of projecting parts 21 have an area corresponding to 10 to 80% of a space S between light sources 1. If top parts 22 are lower than center positions of light sources, this constitution is not much effective. If the height of top parts 22 is higher than 80% of the distance (d), reflection in middle parts between projecting parts 21 is increased to reduce the quantity of light reaching the vicinity of top parts 22 and the lightness is reduced, and trouble occurs the that the uneveness of luminance of the panel light source has directivity by the direction of reflection. If the area of rise bottom parts 23 is 10% of the space between light source 1, the brightness is less increased; and if it is >=80% of this space, the vicinity of light sources 1 is too bright to display the improvement effect for the uneveness of luminance.

Abstract: PURPOSE:To permit a large number of samples to be automatically, speedily and accurately pipetted by providing sucking and pressuring means selectively operated between a suction means and a pipetting means movable laterally and longitudinally. CONSTITUTION:By the operation on an operator's console 1', suction nozzles 2 lower, according to a program previously stored, to the separation level between the supernatant portion and precipitated portion of a sample by the drive of a motor, and then suck the supernatant portion by the operation of a pump 3. At this time, pipetting nozzles 2' are held right above cups 41-45 of a sample cup 4 and at the highest position. Then the pipetting nozzles 2' lower into the cups 41-45 of the smple cup 4, and start pipetting by the operation of the pump 3. Because the pipetting amount has been previously set for each fractionation, the pump 3 stops when having pipetted a prescribed amount. This completes the first pipetting. The pipetting nozzles 2' repeat this until reaching a sample cup 8, into which the whole sample remaining in the nozzles 2' is exhausted.

Title: Interface device
Inventor: SATOU OSATOSHI
IPC: H03M7/00
Filed: 1977-10-20
Abstract: PURPOSE: To dissolve the synchronous shift caused by the transmission delay of the signal by using the pre-write clock pulse preceding to the write clock pulse to accelerate the transmission of the writing data from the data transmitter side.  
     CONSTITUTION: When magnetic drum memory unit C transmits index clock pulse IC (B←C), pre-write clock pulse PWC generator PG in interface unit B generates PWC. Then write clock pulse WC (B←C) generated from unit C follows PWC. These pulses are given to computer A a series of write clock pulse WC (A←B), and computer A transmits writing data WD earlier by the amount of PWC to give FIFO of unit B. After this, the contents of FIFO is read out following WC (B←C) to be sent to unit C. In this case, if the number of PWC and the step number of FIFO are set properly, the transmission delay of the signal is compensated between unit B and computer A. Thus, the synchronization can be secured between WC(B←C) and WD

Abstract: PROBLEM TO BE SOLVED: To restrain overvoltage, increase of error and waveform distortion which are caused by higher harmonic currents contained in a primary current, by installing a bandpass filter(BPF) which cuts off frequencies except a measuring frequency, in the output circuit of the secondary winding of an air-core current transformer. SOLUTION: An overvoltage limiting circuit 6, a voltage follower circuit 7, a BPF 8, a voltage amplifier 9 and a phase shifting circuit 10 are connected with the secondary winding output circuit of an air-core current transformer of a current detecting part 5. The circuit 6 consists of resistors and capacitors, and restrains an overvoltage due to higher harmonic currents contained in a voltage to be measured. The circuit 7 prevents the BPF from being affected by inductance and wiring resistance of the current detecting part 5, and resistors and capacitors of the circuit 6. The BPF 8 is used as the countermeasure for higher harmonic currents due to the air-core current transformer, and cuts off frequency components except the frequency to be measured. The gain is changed and adjusted by the voltage amplifier 9. The phase is changed and adjusted by the phase shifting circuit 10.  Thereby a voltage having an arbitrary phase to an input voltage is outputted.

Title: Initial shift controller of robot
Inventor: GOTOU AKIYOSHI
IPC: G05B19/4155
Filed: 1984-06-19
Abstract: PURPOSE:To perform a smooth initial shift of a robot from its initial position to the working start position by providing a total distance calculating means, a division number deciding means, a function value calculating means, a section distance calculating means and an operating amount output means. CONSTITUTION:A total distance calculating means 2 calculates a distance L between a working end position Q and a working start position P from the coordinates of these positions Q and P. If the distance L is set at 100, a division number deciding means 3 decides that the distance L belongs to the 1st distance level A1 since the L is <1,000. In this case, the division number (m) is obtained from L/10 to satisfy m=10. A function value calculating means 4 obtains only the number (m) from a function F(i)={(m-1)!/(m-i)!}X{i/(m<i>)}. A section calculating means 5 obtains a section distance Sk as Sk=L.F(k)/SIGMAF(i). Then the means 5 deletes the section distance where the calculation value is set at 0 and then adds section distances successively to decide validity for the section distance up to the one closest to the distance L. An operating amount output means 6 converts the section distances S1-S10 into the operation amounts of a robot 10 and delivers them for every shift unit time.
