Title: Device for kneading cement for solidification treatment of radioactive waste
Inventor: FUKAO AKIRA
IPC: G21F9/30
Filed: 1989-06-28
Abstract: PURPOSE:To allow the continuous kneading of water and cement for a solidifying material by continuously kneading the cement for a solidification treatment and the water and providing a discharge means which can change an effective opening rate at one end of a kneading tank. CONSTITUTION:A prescribed amt. of the cement for the solidifying material is charged from a cement silo 1 into a measuring tank 3. The charged cement for the solidifying material is sent to a cement feeder 6. This cement feeder 6 supplies the cement for the solidifying material at a prescribed rate per unit time to the kneading device 9 by a controller 7 for the rotating speed of the cement feeder. The deviation signal based on the difference between the prescribed supply rate and the actual supply rate determined by the computation of a change rate in the weight is impressed to the controller 7 to change the rotating speed of the cement feeder by the controller 7 when the supply rate is not within the prescribed range. The supply rate is thereby so controlled as to attain the prescribed value.

IPC: G04C3/14
Filed: 1979-12-21
Abstract: PURPOSE:To change pulse width continuously with respect to the change in the temperature of the environment used and prevent a pulse motor from stopping at the low temp. time by adding an integrating circuit consisting of a capacitor and a temp. sensing element having a negative temp. characteristic. CONSTITUTION:A crystal oscillation circuit 1, a frequency dividing circuit 2, and a pulse width control circuit 4 consisting of an integrating circuit 4b consisting of a temp. sensing element 4c such as thermistor having a negative temp. characteristic and a capacitor 4d and an NOR circuit 4e having threshold voltage between a waveform shaping circuit 3 and a driving circuit 5 of a pulse motor 6, are provided.

Title: Touch response apparatus for keyed instrument
Inventor: GOMI MINE
IPC: G10H1/053
Filed: 1987-07-03
Abstract: PURPOSE: To provide capability which is close to the expressing power of a piano by using a magnet and a coil and controlling sound generation by making good use of electromagnetic induction. CONSTITUTION: The magnet 2 is fitted to one end of a key 1 on the opposite side from its key hit part and when the key 1 is pressed, the magnet 2 moves up around a support part 5 as a fulcrum; the moment the magnet enters the coil 3, an induced current flows to the coil in proportion to the strength of the key hitting, so this current is used as a control signal for the loudness of sound generation of the musical instrument. At this moment, a sound is not generated, so the control signal is temporarily stored in a memory. Then a switch 4 operates the moment the key 1 is pressed down to the bottom to generate another control signal, and the sound is generated with the intensity controlled with the previously stored control signal. Consequently, a natural feeling is obtained at the time of a musical performance.

Abstract: PROBLEM TO BE SOLVED: To produce a member having excellent erosion resistance to nonferrous molten metal by forming a moisture-contg. oxidized film or a moisture-contg. nitrided film on the surface of an Fe base material. SOLUTION: For example, at the time of heating the stock of an Fe base material at 400 to 1200 deg.C in an oxidizing atmosphere in which steam is present, a dense oxidized film hard to peel is formed on the surface. The formed oxidized film is extremely excellent in erosion resistance to nonferrous molten metal, particularly, to aluminum and zinc molten metal, and is most excellent in the resistance to aluminum molten metal above all. Other than the Fe base material, an Fe-Cr base alloy may be used. The content of Cr in the alloy is regulated to 5 to 40wt.%. The stock is composed of the Fe-(Al or Si) base allay and is subjected to oxidizing treatment, nitriding treatment or oxygen nitriding treatment. Thus, it makes a large contribution toward the field of nonferrous metal casting.

Title: Holder of rotation detecting element and mounting structure thereof and motor provided with the same
Inventor: KAMOKI YUTAKA
IPC: G01D5/245
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To enable mounting, to a narrow space, of a rotation detector using a small diameter encoder disk, by sandwiching a mounting portion of a supporting base plate in the vertical direction, and engaging in the forward and backward direction to move a couple of groove portions formed opposing to or back-to-back to the holder of rotation detecting element. SOLUTION: A couple of groove portions formed to a holder 5 of a rotation detecting element 4 are engaged with the plate type mounting portions 30, 31 formed to a supporting base plate 8 and the plate type mounting portions 30, 31 are vertically sandwiched by the groove portions. The mounting surface is deposited closely to the mounting surface of the supporting base plate 8 to maintain the right angle characteristic of the rotation detecting element 4 to the supporting base plate 8 and it can also be moved in the forward and backward direction to adjust a gap between an encoder disk 2 and rotation detecting element 4. A gap of groove portions is set a little smaller than the gap S2 of the plate type mounting portion formed to the supporting base plate 8.  Therefore, even if the holder 5 is moved in the forward and backward direction, deviation between the center shaft of encoder disk 2 and the center of rotation detecting element is never generated.

Title: Electrolyte for phosphoric acid type fuel battery
Inventor: SUZUKI YASUO
IPC: H01M8/08
Filed: 1989-06-30
Abstract: PURPOSE:To prevent freezing even when operations are suspended under a low temperature environment by incorporating non-conjugated non-organic salt with strong phosphoric acid electrolyte. CONSTITUTION:Non-conjugated non-organic salt which is different in molecular structure, size and ionic properties is incorporated with strong phosphoric acid electrolyte so as to be transformed into an ion mixture formation, and the mono-crystallization of strong phosphoric acid is so inhibited that its freezing point is lowered. Namely, when an ionic material which is different in molecular structure, molecular size and electrical loading, is mixed, the formation of crystal lattice of phosphoric acid, that is, the formation of crystal nucleus is inhibited so that freezing hardly takes place. Non-conjugated non-organic salt has no constituent ion which is mutually common to strong phosphoric acid, each ion is however, allowed to stably lie in mixedly in strong phosphoric acid because of electrical loading balance, thereby inhibiting the mono- crystallization of strong phosphoric acid. Phosphoric acid to be used shall be, if desirable, usually in the amount of 80 to 105% in terms of ortho phosphoric acid.

Filed: 1981-10-19
Abstract: PURPOSE:To simplify the production process and to unify the quality by punching a small ring and guard bars from a sheet of metallic plate so as to form them concurrently in one body. CONSTITUTION:A zigzag cutout 7 is punched on a rectangular metallic plate 6 leaving belt strips 6a with a little width on both sides in the lengthwise direction, thus forming comb teeth 6b.

Abstract: PURPOSE:To obtain a resin drive lever which can prevent grease from flowing outside caused by permeation of water into a starter so as to be scarcely worn out by forming a plurality of independent grooves on both the contact face of said lever with a clutch and the contact face of said clutch with the lever and filling said grooves with grease. CONSTITUTION:A drive lever 1 made of resin is supported by a housing 4 via a lever holder 9 and makes contact with both a magnet switch 7 at one end of said lever 1 and a clutch 5 at the other end thereof. A plurality of independently formed grease holding grooves are formed on both the contact part of the drive lever 1 with which the clutch 5 makes contact, and filled with lubricating grease. Furthermore, a plurality of grooves are formed on the rubbing face of the clutch 5 with said lever 1, and filled with grease. Both the entire friction faces of the driver lever 1 and the clutch 5 can then be lubricated with grease, if a starter is immersed, and no grease flows outside because the grooves are formed independently from each other, so that due to the high grease holding effect, the durability and life of the starter may be improved and elongated.
