Title: Differential gear
Inventor: MIWA YUICHI
IPC: F16H48/38
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To provide a large limited differential force when the difference is large by changing the limited differential force according to the difference in a differential gear having the limited differential function to mechanically limit the difference. SOLUTION: When the rotational speed of a side gear shaft 16a is larger than that of a differential case 14, and the phase difference ϕ per rotation reaches the limited differential phase difference -ϕ0 , a ball 38a is abutted on a projected engagement part 14b, and the diff-lock condition is realized if the phase difference ϕ≈-ϕ0 in that condition. When the projected engagement part 14b reaches the position of a recessed part 12a in the condition (b), the ball 38a enters the recessed part 12a to release the engagement with the projected engagement part 14b, an intermediate rotary member 36 is rotated in the + direction by ϕ0 as in the condition (c) by a spring 34a of a relative rotation limiting means 40 to reset the phase difference ϕ to zero.  When the phase difference ϕper rotation is -ϕ0 <ϕ<+ϕ0 , the difference is absorbed by the elastic deformation of the springs 34a, 34b.

Abstract: PURPOSE:To facilitate the work of hitching a rope to a curtain rail by using a main body of a tool having a retaining mechanism, and a sliding member which is slidable in relation to the main body and has broach with a rope-holding part, which is engaged with said retaining mechanism. CONSTITUTION:When a slide member 2 is hitched to a curtain rail 14 together with a main body 1 while the lower end of the base 1a of the main body is gripped, it comes down to the lower dead point of slide member under its own weight. The main body 1 is pulled down in this state, and broach 9 of the slide member 2 is engaged with a retaining mechanism 4 of the main body 1. When the main body is then lifted, the slide member 2 is left as it stands under its own weight with its upper side part 2a being contact with the curtain rail 14, while the broach 9 is lifted up together with the main body 1 since it is engaged with the retaining mechanism 4. By moving the main body 1 successively so as to disengage it from the curtain rail 14, a rope 8 held by the broach 9 is hitched to the curtain rail 14.

Filed: 1981-01-14
Abstract: PURPOSE:To obtain a sound casting by controlling the heating temp. at the sprue of dies finely in pressurizing the molten metal in a hermetic furnace and teeming the same into the dies placed in the upper part through a stalk. CONSTITUTION:At the same instant when dies 4 are heated, electricity is conducted to a heater 5 to heat a heater block 7. The output of a temp. sensor 6 is fed to a controller 8, which controls the block 7 to a constant temp. Thereafter, pressure is applied to a heat insulating furnace 1 for molten steel to teem molten steel 2 through a stalk 3 into the dies 4. Solidification begins from the upper part of the dies 4 having no heaters, and when the solidification in the part corresponding to a casting ends, the pressure air is removed and the unsolidified part is returned to the original. In this way, the waste of the molten metal is prevented and the sound casting is obtained.

Title: Cipher communicating method for facsimile equipment
Inventor: SHIBATA KOICHI
IPC: H04N1/44
Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To prevent a cipher sentence from being decoded by means of a third person by transmitting information for specifying the constitution of a cipher key system generation part to a reception-side facsimile equipment from a transmission-side facsimile equipment in the pre-process of a communication protocol. SOLUTION: The transmission-side facsimile equipment ciphers data encoded in an encoding part 15 by using a cipher key system generated in the cipher key system generation part 2 and generates the cipher sentence. When the reception-side facsimile equipment receives an NSS signal and a TCF signal, which are transmitted from a transmission-side, it judges whether it is cipher communication or not. When it is cipher communication, the initial value of a shift register in the generation part 2 is read and it is set in the shift resister. Information for specifying the constitution of the generation part 2 is read and stored from the NSS signal, the TCF signal is read and the quality of a picture is checked. Then, the CFR signal is transmitted.  When the cipher sentence is sent to a network control circuit(NCU), reception data is demodulated in MODEM 17 and it is returned to a normal sentence.

Abstract: PURPOSE:To provide uniform feeding of air into a combustion cylinder and to prevent generation of clinker by a method wherein air guide vanes of which inclined directions in respect to their radial lines are opposite to each other are arranged on the inside circumferential face of the side wall of the combustion cylinder and a grid is arranged at the lower part of the combustion cylinder. CONSTITUTION:Air fed into a combustion cylinder 6 through air flowing holes 30 is guided by air guide vanes 28 and flows in a space having a size of H with its laminer flow condition. Solid fuel dropping from above due to the air flow is gathered at the central part of the combustion cylinder 6. In turn, since inclination of about half number of air guide vanes 28 in respect to their radial lines is opposite to that of the remaining air guide vanes 28, the air after having passed through the air guide vanes 28 shows a turburent flow near the central part of the combustion cylinder 6, resulting in making a sufficient mixing of air. A part of the air passes through the grid 26 and flows into the combustion cylinder at the lower part thereof. Thus, it is possible to make uniform feeding of air.
