Title: Growing method for crystal of sodium bicarbonate
Inventor: NAKAYA KEIICHI
IPC: C01D7/40
Filed: 1985-05-02
Abstract: PURPOSE:To obtain sodium bicarbonate which is large in the crystal and having a shape close to a cube by adding a small quantity of sodium tartrate (derivative) into a mother liquor. CONSTITUTION:About 1-50,000ppm sodium tartrate or its derivative is added to a saturated aq. soln. of sodium bicarbonate. The crystal of sodium bicarbonate is deposited from the aq. soln. with a method such s the evaporation, the cooling and the deposition due to a reaction. Sodium tartrate acts as a crystallizing agent and the growth of the crystal of sodium bicarbonate is accelerated thereby. Even when the extremely small quantities of the crystallizing agent remain in a product, any trouble is not caused in case of its use.

Title: Vibration suppressing device
Inventor: MASUDA TAKUYA
IPC: E04H9/02
Filed: 1989-04-13
Abstract: PURPOSE:To reduce the vibration of the damping performance accompanied with the wave motion of liquid by installing at least one baffle plate in shiftable manners in the vertical direction onto the both sides in the wave motion direction of a tank and installing a floating-up means onto the baffle plate. CONSTITUTION:When an oscillation is generated in the direction of arrow C-D on a building 6 because of an earthquake, wind, etc., wave motion 3b is generated in the direction C-D on the liquid 3 in a tank 2, and each baffle plate 5 shifts, together with the shift of the liquid surface 3a, in the direction of arrow A-B by the action of a float 5a. Since, the plate 5 on the left side has a constant length L1 from the float 5a to the lower edge 5c, the equal resistance is generated onto the liquid 3 which oscillates in the direction C-D, and the constant damping performance is maintained, so for as the lower edge 5c does not contact the tank bottom surface 2a. The lower edge 5c of the right side plate 5 contacts the bottom surface 2a, and the damping performance varies according to the contact distance L2 between the plate 5 and the liquid 3, and the wave motion energy of the right side liquid 3 is markedly less than that on the left side, and the slight variation of the damping performance at this part reduces the variation of the damping performance of the whole of the vibration suppression device 1.

Filed: 1989-04-13
Abstract: PURPOSE:To realize automatic answering for practical use by answering a telephone call when it arrives, and re-recording a message when a user is absent, and stopping re-recording at the point of time when the talk of a caller is decided to have been finished perfectly. CONSTITUTION:A voice recording circuit 9 to record the voice of a caller inputted from a receiver 3 into an IC memory 10, a regeneration circuit 12 to regenerate the recorded voice and output it from a speaker 11, a ringing tone signal generation circuit 13 to generate a ringing tone signal, and a voice signal level detection circuit 15 are provided. A control circuit 7 records a voice which the caller generates, and when it detects that the voice is silent extending over time longer than prescribed time after the lapse of prescribed time, it stops the recording, and executes the calling of a ringing tone and recorded contents. Then, when an off-hook state is not attained even after the calling of the prescribed time, it re-records the message, and after detecting the silence extending over the time longer than the prescribed time, it continues re-recording for the prescribed time further, and stops. Thus, the automatic answering convenient for both the caller and the user can be realized.

Title: Wave motion gearing
Inventor: KUMAGAI TOSHIKI
IPC: F16H1/32
Filed: 1989-04-13
Abstract: PURPOSE:To eliminate sliding sections out of a wave motion generator, and thereby eliminate countermeasures for wear resistance by making up the wave motion generator out of a means generating a rotating magnetic field, and of a magnetic field which is hermetically enclosed in such a way as to be capable of being moved around the circumference of the rotating magnetic field. CONSTITUTION:Only paired electromagnets for example, 9a and 9b which are faced with each other in the direction of diameter, are magnetized first out of electromagnets within a member in a circular shape. This causes magnetized fluid 7 to be attracted only to the circumference of the electromagnets 9a and 9b while a flexspline 3 is being formed into an ellipse wherein the dimension connecting the electromagnets 9a and 9b results in its major axis. In the second place, when said paired electromagnets 9 which are faced with each other is for example, magnetized continuously clockwise so as to let a rotating magnetic field be formed, a magnetic body together with the magnetic field is moved along the circumference of a member 8 in a circular shape as the magnetic field is moved clockwise. By this constitution, it appears that the ellipse formed by the flexspline 3 would be rotated clockwise, the meshing position of a circular spline 2 with the flexspline 3 is moved, the output can thereby be obtained with no sliding section developed.

Title: Grit scraper
Inventor: KOJIMA MASAYUKI
IPC: B01D21/06
Filed: 1979-07-25
Abstract: PURPOSE: To make the titled apparatus sure to scrape and free from corrosive abrasion by moving upward the oscillatable and elevatable scraping slide arm provided to the arm traveling along an endless guide, when overloaded, thereby controlling the load.  
     CONSTITUTION: An endless chain 3 is driven in the arrow direction. Along with this, an arm 6 with rollers, a telescope 8 and a scraping slide arm 11 are also conveyed along a guide 4 and a scraper 13 makes reciprocative elliptical motion shown by the chain lines. The grit 14 in the basin bottom is scraped at one point and is discharged to outside the water channel 1 by a pump P. If there is a large amount of deposited grip 14, the scraper 13 is caught by the grit 14 and the telescope 8 tilts by overcoming the energizing force of a cushion 10. Then, a detector, not shown, operates to retract a cylinder 12 thereby moving the arm 11 upward. Hence, the load upon the scraper 13 decreases and the arm 11 is put perpendicular by the energizing force of the device 10, thus the grit 14 is successively scraped from the upper layers of the grit 14. In the next scraping, the cylinder 12 is again extended and the above-metioned operation is repeated.
