Title: Self-conscious refraction measuring device
Inventor: KOBAYAKAWA YOSHI
IPC: A61B3/028
Filed: 1994-04-30
Abstract: PURPOSE:To dispense with a special optical member and measure the ophthalmic refraction by the operation of a testee itself by providing a target observing system for varying the diopter of the target generating at least three-directional stripe patterns and a responding means for the response by the testee, and determining the refraction value from the diopter of the target at response. CONSTITUTION:At measurement, any one of a plurality of stripe patterns is displayed on a target 2 by a target generating means 4, and a testee observes the target 2. The target 2 is driven in X-direction in this state by a driving means 3 to change the diopter, and at the point of time when the testee can visually confirm it, he pushes down a control lever 7 in the direction of the same stripe pattern on a responding means 6 to respond it. According to the response signal, another stripe pattern differed in the direction or pitch of the stripe pattern is shown, the diopter regulation is similarly performed, and the following refraction value is calculated from the diopter at the point of time when the testee responded. The pitch of the stripe pattern is gradually set fine to rough, and the visual acuity is measured from the pitch when the testee visually confirmed it.

Title: Ladder type filter
Inventor: NISHIMURA TOSHIO
IPC: H03H9/58
Filed: 1993-04-15
Abstract: PURPOSE:To provide a filter with high precision in which attenuating amounts can be easily ensured, and the temperature change of a frequency is small by using piezoelectric single crystal resonators as serial resonators, and using piezoelectric ceramic resonators as parallel resonators. CONSTITUTION:A ladder type filter is constituted of 4 elements. The resonators in a thickness-shear vibration mode made of the X board of LitaO3 being the piezoelectric single crystals are used as serial resonators 1 and 2, and the piezoelectric ceramic resonators in the thickness-shear vibration mode made of PZT (registered trademark) are used as parallel resonators 3 and 4. Especially, a damping material made of silicon gel is applied to at least the vibrating parts of the serial resonators 1 and 2 in order to reduce spurious. At that time, the dielectric constant of the PZT is more than 700 while the dielectric constant of the X board of the LitaO3 is 44, and the capacity rate is more than 15. Thus, the attenuating amounts can be easily obtained without connecting any individual capacitor.

IPC: B65G65/40
Filed: 1979-09-04
Abstract: PURPOSE: To flow continuously a predetermined amount of grain through a chute by providing a rotary type transfer conveyer in a corn feeder of a color discriminator.  
     CONSTITUTION: When a grain differing in color are dumped into a supply hopper 3, the grain overflows from a lower outlet 15 of the hopper to the upper side belt surface, flows into a chute 4 through a discharge chute 16 for regulating a predetermined amount of the grain according to an opening of the chute 16 and slides along a grain flowing surface 17 into a photoelectric discriminating chamber 8. In the discriminating chamber, a photocell 5 receives light rays reflected from the grain differing in color to generate detecting signals by which blast from an injection nozzle 7 blasts selectively grains differing in color out of the flow track. The blasted grain drops from an outlet 10 and the grain flowing along the flow track flows into a corn collecting tube 11 as it is.

Abstract: PROBLEM TO BE SOLVED: To improve the pickling property and the surface characteristic in a low cost by executing descaling before finish-rolling with high pressure jet suitably controlling the pressure after completing a rough-rolling and applying a specific condition of heat treatment and oxidizing treatment. SOLUTION: In the rough-rolling process, a cast slab containing 0.005-0.10wt.% Ni executes the descaling with the high pressure water jet exceeding 160kgf/cm<2> at one or more times, and the rolling is executed so as not to exceed 1170 deg.C after descaling. After rough-rolling, the heat holding treatment is executed so that a heat holding temp. T ( deg.C), heat holding time (t) (min) and Ni content [Ni] (wt.%) in the atmosphere having >=3% oxygen concn. satisfy the formula (1). Thereafter, a finish-rolling is executed after descaling in the condition the pressure P of the high pressure water jet satisfies the formula (2). Wherein, T is 950-1170 deg.C. In this result, the produced scale thickness is made to thin and the pickling property can be improved.

Title: Rotary dresser and manufacture thereof
Inventor: HARA TOMOYOSHI
IPC: B24B53/14
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To reduce an unbalance amount without causing any weight unbalance at a bonding process, and shorten a time required for balance adjustment by applying a specific value to the density of a particle-mixed resin layer. SOLUTION: This rotary dresser has a resin layer 5 with the density of a particle-mixed resin layer formed on the internal surface of a diamond layer 2 so as to have derasity between 4g/cm<3> and 7g/cm<3> , and this resin layer 5 is fixed to a mandrel 6 via an adhesive 7. When a resin is cured to form the resin layer 5 under exposure to a centrifugal force, both the resin and the diamond layer 2 are also pressed to a matrix, due the centrifugal force. As a result, the diamond layer 2 becomes almost free from strain. Furthermore, when the mandrel 6 is secured via an adhesive after cutting the resin layer 5, the strain of the diamond layer 2 due to the hardening and shrinkage of the adhesive is slight, as the thickness of the adhesive layer is small. Thus, a correction amount required for the diamond layer 2 becomes small.

Title: Failure analyzing apparatus for electric rolling stock
Inventor: KAMINAGA MINORU
IPC: B60L3/00
Filed: 1979-09-07
Abstract: PURPOSE: To perform the safe checking operation by a method wherein a plurality of contactors are continuously closed and conrolled and the presence of failures is checked by the presence or absence of the sound at the closing operation, by opening the contactor which has been closed at first, then, invariably closing the next contactor.  
     CONSTITUTION: In the case bypass contactors are checked; when a push button 42 is depressed, a push button 41 is opened, a transistor TR1 becomes nonconductive, the current does not flow in a contactor coil 37, and a conact 36 is opened after t 1 . When the push button 42 is depressed, a thyristor SCR is fired after the time t 2 , and a bypass contactor 38 is closed. The resistance of a resistor R 1  and the capacitance C 1  are determined so that t 2 >t 1 . Since the next contactor is closed invariably after the previously closed contact has been opened, the time during which both contactors are closed is eliminated, and the safe checking operation can be performed.
