Title: Method for measuring acid value and base value of lubricating oil
Inventor: TAMURA KUNIMITSU
IPC: G01N31/00
Filed: 1987-06-30
Abstract: PURPOSE:To measure the acid value and the base value in lubricating oil quickly without skill, by continuously neutralizing and reacting acidic or basic component in the sample lubricating oil in a tubular reactor, and continuously detecting the pH change in reacting liquid. CONSTITUTION:A sample lubricating oil is sent to a stirring part 4 through a check valve 3 with a constant quantity pump 2. Meanwhile, a mixing solvent including an indicator is sent into the stirring part 4 from a mixing solvent capsule 7. An electromagnetic stirrer 5 uniformly dissolves the sample lubricating oil into the mixing solvent. The sample and the solvent are continuously sent into a next stirring part 4' through a check valve 3'. Furthermore, standard titrating liquid in a standard titrating liquid capsule 9 is injected through a branch pipe, which is provided between the check valve 3' and the stirring part 4', with a constant quantity pump 10. Said liquid is mixed, neutralized and reacted with the sample and the solvent liquid. Then the liquid is continuously sent into the stirring part 4'. The color changing step of the mixed liquid is detected in a neutralization detecting part 11 and recorded as a light transmitting rate through a photodetector 15. The Acidic or basic component in the sample lubricating oil is determined based on the flow rate ratio of the standard titrating liquid to the sample lubricating oil at the terminating point of pH change.

Abstract: PURPOSE:To prevent the individual difference of inspection operation by conducting operation holding up a wafer by a pushing-up tool while performing the feed operation of the wafer by a cam and a parallel link mechanism. CONSTITUTION:A wafer carrier 2 in which a semiconductor wafer 4 to be inspected is housed is set to a carrier slider 20. When a handle 5 begins to be turned in the direction B from the direction A, revolution is transmitted over a crank 7 by a crankshaft 6, a slider 8 is lifted through a rod 9, and a pushing-up tool 10 pushes up a semiconductor wafer 4a. An operator visually inspects the surface of the semiconductor wafer 4a at the position. When the handle 5 is rotated after inspection, a link 22, over which revolution is transmitted from a bevel gear 14, is swung in the direction C while a mounting block 17 is used as a fulcrum, and a lever 19 is elevated and engaged with a ratchet 18. When the handle 5 is further turned, a link 23 is swung in the direction E while the mounting block 17 is employed as the fulcrum, and moved by one pitch together with the slider 20 and the wafer carrier 2. Accordingly, an inspection method and the inspection time by the operator are unified approximately, thus shortening the time for inspection operation itself.

Abstract: PURPOSE:To eliminate unevenness of color of a polarizing plate by pasting polyester films each having min. or max. refractive index in the direction parallel to the almost equal to the refractive index in the film thickness direction, and a specified retardation to both sides of a polarizing film with an adhesive. CONSTITUTION:Both sides of a polarizing film are pasted with protective films, such as stretched polyethylene terephthalate (PET) films, each having max. or min. refractive index in the direction parallel to the film surface almost equal to the refractive index in the film thickness direction, and >=10mum retardation, and further tantheta' satisfying a specified value, i.e. principal refractive indices (nx), (ny), (nz) satisfying equation I , using a layer of adhesive, such as polyester. Since such a PET film has >=10mum retardation, colored interference fringes are not observed from the normal direction, and also since equation I is satisfied, and theta exceeds 90 deg. in accordance with equation II, colored interference fringes are not observed from the inclined directions, too, thus eliminating unevenness of color.

Title: Fm demodulating circuit
Inventor: HONJO MASAHIRO
IPC: H03D3/00
Filed: 1987-07-02
Abstract: PURPOSE:To prevent an FM reversal phenomenon without changing the zero cross point of a normal FM signal by sending an FM reproduced signal to a demodulator after superposing the small interval of the pulse of the same polarity as the polarity of an FM wave, to the peak point of the FM reproduced signal. CONSTITUTION:A peak detecting circuit 2 outputs information (c) showing the peak point of the reproduced FM signal (a), and a pulse generating circuit 3 generates the pulse (d) of a positive direction at the leading edge of the signal (c), and generates the pulse (d) of a negative direction at a trailing edge, and an adder 4 sums together the signal (a) and (d), and obtains the signal (e). Here, because the pulse generation point of the signal (d) coincides perfectly with the peak point of the signal (a), as for the signal (e), the pulse is due to be superposed always to the peak point of a waveform. Thus, the said signal (e) reproduces the zero cross point at the interval, during which the reversal phenomenon has been generated customarily, and even if it is inputted to the demodulator 5 of a pulse counter type, the reversal phenomenon is never generated, and good FM demodulation is realized.

Filed: 1983-09-07
Abstract: PURPOSE:To prevent the excessive exposure due to the reflected light at pattern exposure by performing the last precess of spattering of the metal for wiring by using the mix gas of an inert gas and a reactive gas. CONSTITUTION:The substrate 1 treated by the predetermined process is subjected to spattering using an inert gas 4 to deposit the metal film for wiring 2 on the substrate 1. Next, in the last process of the spattering, spattering using the mix gas 11 of the inert gas and a reactive gas is performed to form a reactive product layer 12 on a surface of the film 2. Then, the layer 12 is coated with a photosensitive resin film 5 which is irradiated with the light 7 through a patterning masking plate 6 to perform exposure. The pattern on the plate 6 is transferred onto the film 5 and a resin pattern is obtained. At this time, the layer 12 is formed on the film 2 so that reflection of the light 7 is small at the exposure. Accordingly, the excessive exposure to the film 5 is prevented and the resin pattern of high accuracy can be obtained.
