Title: Optical measuring device
Inventor: UMEMOTO TAKASHI
IPC: G01N21/53
Filed: 1981-07-23
Abstract: PURPOSE:To enable to perform an accurate correction at an arbitrary time without being affected by an external environment, by a method wherein a separate optical path consisting of an enclosure piping is installed between a projector and a collector, and it is caused to serve as a reference for correction. CONSTITUTION:In the case of an usual measuring time, one light 4a from a lamp 16 reaches a collecting part 2 through lenses 17a and 17b and a half mirror 18a, and the other light 4b arrives at the collecting part 2 through the half mirror 18a, a fixed mirror 18b, a lense 17c, and an enclosure piping 14. The lights, passing the lenses 27a, 27b and the half mirrors 28a, 28b, are converted into an electric signal by photoelectric elements 29a and 26b, and are compared by a comparator 31 after passing amplifiers 210a and 210b, and a sensitivity regulating resistance 311 to detect the degree of contamination of air due to smoke and dusts 5. Meanwhile, at a correcting time, the light 4a is shut off with the mirror 28a moved, and the light 4b reflected by the half mirror 28b is sent to a photoelectric element 29a to perform a correction.

Title: Dynamic pressure bearing device
Inventor: NAKASUGI MIKIO
IPC: F16C17/04
Filed: 1989-05-11
Abstract: PURPOSE:To enhance the characteristic of a bearing, in a dynamic-pressure bearing device in which a communicating hole is provided to a thrust plate or on the side surface of a shaft, by thinning the thickness of the thrust plate in the inner circumferential part thinner than that in the outer circumferential parts, so that the shape accuracy of the thrust plate can be easily attained even by forming working. CONSTITUTION:When a turning shaft 1 is turned, the fluid between a sleeve 2 and a thrust plate 103 is forcibly fed to the central part by grooves 11, so that the turning shaft 1 is floated up. The thrust plate 103 is formed with resin material, and the amount of shrinkage due to the cooling after forming working is proportional to the thickness, and the shrinkage is caused toward the part where cooling is latest, so the shrinkage occurs in the direction toward the marks x. In this thrust plate 103, as mentioned above, due to the difference in thickness between the outer circumferential part and the inner circumferential part, the shape of the bearing surface after shrinkage is formed in a convex shape slightly higher in its central part as shown by the broken line. Thus, in the accuracy, the deviation in the flatness becomes very small, and the frictional torque at the time of start is reduced, and abrasion is hardly caused.

Title: Thermal head
Inventor: SUZUKI TAKUMI
IPC: B41J2/335
Filed: 1986-05-20
Abstract: PURPOSE:To obtain a thermal head having a function of absorbing cracks, by using a second protective film made by a material being flexible as compared with materials for first and third protective films between which the second protective film is located. CONSTITUTION:A protective layer 17 has a three-layer construction in which a central layer 9 is formed of a flexible material so that cracking cased by mechanical deformation is stopped by the flexible layer. Namely, the protective layer 17 comprises at least a first protective film 8 consisting of an SiO2 film, a second protective film 9 formed of a flexible material and a third protective film 10 having excellent abrasion resistance, which are sequentially layered to constitute the three-layer construction. Where an extremely hard dust 11 is adhered to a printing part, the hard third protective film 9 is cracked when, for example, the pressure of a platen roller 13 is exerted on the dust 11 through a thermal recording paper 12. However, stresses arising from the cracking are absorbed by the flexible second protective film 9, so that a Ta2N resistor layer 5 is prevented from being fatally damaged.

Abstract: PURPOSE:To surely hold a thin original with no fear of generation of wrinkles and position deviations by providing a transparent conduction layer and an optical reading coordinate component layer to a transparent coordinate plate which is adsorbed onto the surface of an electrostatic attracting plate via the original to be read. CONSTITUTION:A transparent coordinate plate 30 consists of a transparent conduction layer 32, an optical reading coordinate pattern 34 formed on the layer 32, and a transparent base layer 36 which covers the layer 32 and the pattern 34. An original 40 put on a electrostatic attracting plate 20 is pressed by the plate 30. Then the electrodes 24a and 24b are connected to a DC power supply. Thus and electric field pierces through an attraction layer 26 and the original 40 to reach a part of the layer 32 from the electrode 24a and then fed back to the electrode 24b after piercing again through the original 40 and the layer 26 from another part of the layer 32 since the distance between the saw tooth parts is smaller than the distance between the layer 32 and the electrode 24 which hold the original 40 between them. As a result, the original 40 is held flat and firmly with no wrinkles produced.

Title: Fet computing method using dsp
Inventor: KAWAZOE AKIHISA
IPC: G06F17/14
Filed: 1990-05-07
Abstract: PURPOSE:To attain the fast Fourier transformation FFT with use of an inexpensive audio digital signal processor DSP by using one of two processors of a dual processor structure for the real number part operation and the other processor for the imaginary number part operation respectively. CONSTITUTION:When an FFT arithmetic program is written into a program RAM of a DSP 3, an L-channel processor 3a for real number part operation and an R-channel processor 3b for imaginary number part operation carry out the common instructions by one step synchronously with each other at and after the first instruction of the FFT arithmetic program. When the processor 3b is stopped by a certain instruction, the processor 3b stops its processing until a restart instruction is received. Meanwhile the processor 3a carries out a non-common instruction. As a result, both real number and imaginary number part operations can be processed in parallel with each other by means of an inexpensive audio DSP. Then the FFT operation is carried out at a high speed.
