Abstract: PURPOSE:To enable reducing noize even with small intensity of light transmitting a sample and shorten the measuring time by increasing the integration times of measured value only during small intesity of light having transmitted the sample. CONSTITUTION:A lamp W1 for the visible light region and a lamp D2 for ultraviolet region are used and the lamp light is guided to a monochrometer by way of a mirror 1, a filter 5 and a mirror 6. The monochrometer is constituted of an, incident slit 7 and outgoing slit. The monochromatic light dispersed with the monochrometer after passing a mirror 10 is branched with a branching mirror 11 into a light beam on the control side and light beam on a sample side. The light beam on the control side passes mirrors 12, 13, 14 and the light beam on the sample side passes mirrors 15, 16, 17, and go into a detector 19. The shift of wave length is done by changing the rotational angle of a dispersion element 9. The sensitivity of the detector 19 is controlled so that the larger electric signal on the sample side or control side is made constant. Then, the data on the sample side are summed until exceeding a certain value. By this, when the sample side data is larger, the summing frequency becomes small and when it is smaller, the samming frequency becomes large.

Title: Carrier recovery circuit
Inventor: HASEGAWA JUNICHI
IPC: H04L27/22
Filed: 1985-10-30
Abstract: PURPOSE:To improve the deterioration of an error rate by using an error detection circuit generating a pulse in response to a steady-state phase error from the output of an orthogonal synchronizing detector, controlling the self-running frequency of a VCO to minimize the steady-state phase error. CONSTITUTION:When a frequency f1 of a carrier or a self-running frequency f2 of the VCO is fluctuated and a steady-state phase error is caused, the error is detected and the frequency f2 is changed to minimize the error. That is, a BB signal from the detector 1 is used to allow the error detection circuit 5 to generate a pulse corresponding to the steady-state phase error, the pulse is counted by a counter 6 for a predetermined time to compare the preceding count and the present count, and when the latter is less than the former, the self-running frequency of the VCO is changed in the same direction. When the latter is larger than the former, the self-running frequency is changed reversely and when the count is '0', the self-running frequency is kept to the value. Thus, since the steady-state phase error is always kept minimized, and deterioration in the rate is improved.

Abstract: PURPOSE:To improve magnetic characteristics as well as recording sensitivity and reproducing sensitivity and to make density higher by laminating an amorphous Co film on a non-magnetic layer as an intermediate layer. CONSTITUTION:Blocks 7 consisting of ferrite or non-magnetic material and thin non-magnetic sheets 8 are united to one body by glass adhering to manufacture a magnetic pole carrier 9. A surface 10 of the carrier 9 is finished to a specular surface and a groove 12 for a winding 11 is formed to the block 7. The non-magnetic film 14 having several tens Angstrom  thickness is sandwiched by the amorphous Co alloy films 13 to form a main magnetic pole film 15 having 0.1-0.3mum thickness on the surface 10. The film 15 is finished to about several tens - several hundreds mum to form a magnetic pole 16. The other carrier 9 is joined and united to the above-mentioned carrier and the winding 11 is applied to complete the head. The main magnetic pole film 15 according to such constitution permits the reduction of the film thickness of the films 13 to an extra small thickness. The magnetic characteristics are improved when viewed from the structure of the magnetic domains thereof. The recording sensitivity and reproducing sensitivity are thereby improved and the higher density is attained.

Title: Cache memory
Inventor: TAMAOKI SATOSHI
IPC: G06F12/08
Filed: 1988-09-28
Abstract: PURPOSE:To shorten the access time by adding a means to a valid bit register storing valid bits to simultaneously clear all bits. CONSTITUTION:When all valid bits are cleared, an all-clear signal 102 is set at 1 and inputted to the selection input terminal S1 of each of selectors 51 and 5n. In this case, a negative logic clear signal 104 is equal to 0 and therefore the outputs 801 - 80n of AND gates 81 - 8n are equal to 0. Then 0 is inputted to a selection input terminal S0. Thus the selectors 51 - 5n select a 0-clamp signal 100 and output 0 to the outputs 501 - 50n respectively. As a result, 0 is stored into all valid bits 21 - 2n of a valid bit register 2 synchronously with a clock signal 103 and all clear actions are through in a single cycle. Thus it is possible to prevent the generation of the idle time of a processor and to shorten are access time.
