Abstract: PURPOSE:To prevent failure to turn off a work light securely to secure traffic safety by constructing a device so that the work light may be turned off automatically when the high-speed traveling of a tractor is detected by a high-speed detector. CONSTITUTION:In an agricultural tractor, the power of an engine 2 is transmitted to right and left rear wheels 11 through a clutch 12, main and auxiliary transmissions 13 and 13a, rear wheel differential unit 14, etc. Also, the power taken out from the auxiliary transmission 13a is transmitted to right and left front wheels 9 through a gear mechanism 16, high and low speed change-over unit 19, propeller shaft 20, and front wheel differential unit 21. In this case, a high-speed detector 29, turned on through a shift fork when a gear-shift lever 31 is shifted to the maximum speed position, is provided on the main transmission 13. When the high-speed detector 29 is turned on, a relay circuit 44 is energized to turn off the b contact 45 whereby a work light 39 can be turned off even when a manual switch 43 is turned on.

Filed: 1981-07-30
Abstract: PURPOSE:To read and write data with one access, by connecting a master machine consisting of a master CPU and a main memory and a slave machine consisting of a slave CPU, an individual memory, etc. through a DMA controlling circuit by a bus line. CONSTITUTION:A master machine having a memory 2 and a master CPU1 and one or more slave machine having individual memories 12, slave CPUs 11, etc. are connected by busses 3-5. In each slave machine, the address outputted from the slave CPU11 is decoded in decoder 21 to discriminate whether this address is included in addresses of the main memory 2 or not, and the address bus connected to the individual memory 12 is switched in accordance with the output 16. A DMA controlling circuit 22 is provided which sotres temporarily the address signal of the CPU11 by the output of the decoder 21 to request DMA to the master CPU and sends the control signal, which inverts the read/write mode and the  address signal to the main memory 2 when a permission signal is returned. Thus, read and write are performed with one access.

Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive ink jet storage container sealing mechanism suitable for mass production process in which the container can be sealed/ unsealed without causing any deterioration in the sealing properties. SOLUTION: An ink jet storage container sealing mechanism comprises a cover 28, a receptacle 22, a gasket 120 being compressed perpendicularly to the inserting direction, and a supporting member for sustaining seal durable against intrusion of ink and air. The receptacle 22 has a side wall for forming an opening. The gasket 120 spreads over a part of the cover 28 and a part of the gasket 120 and the cover 28 is inserted into the opening of the receptacle 22.

Title: Manufacture of getter device
Inventor: OKAI TADAKI
IPC: H01J9/39
Filed: 1981-08-03
Abstract: PURPOSE:To manufacture a getter device having a good getter effect efficiently by deforming a getter case by applying pressure to the case by pressing or something similar after a getter member is put in the case. CONSTITUTION:An annular metal case 11 one end of which is opened has a square vertical section. In packing a getter member 12 into the case 11 with pressure, pressure is applied by pressing or something similar by use of a metal mold 13. The under die of the mold 13 is provided with a concave part 14 having almost a semi-circular shape. As pressure is applied to the case 11 after it is put in the concave part 14, the getter member 12 is condensed, and the case 11 is deformed in conformity with the shape of the concave part 14. As the result, a getter device consisting of an annular metal getter case 11A, and a getter member 12A packed in the case 11A is obtained. Since the angular part around the bottom of the case 11 is removed by the above pressing work, since friction occuring during the packing of the getter member 12 decreases, and since force caused by the deformation of the case 11 is applied to the member 12, the fluidity of the member 12 is remarkably increased. Consequently, a homogeneity of the packed density of the getter member 12A in the case 11A can be realized.

Abstract: PROBLEM TO BE SOLVED: To form a high-quality image by preventing releasing porperty between a toner image formed on an intermediate transfer belt and the surface of the belt from being lowered and preventing a spotted image from being formed on the toner image secondarily transferred on a transfer material. SOLUTION: When the toner image transferred on the intermediate transfer belt 21 is secondarily transferred on the transfer material 7, an electric field generated on the upstream side of a contact area between the belt 21 and a secondary transfer belt 31 is suppressed by impressing a bias voltage from a bias impressing part 34 arranged on the downstream side of the contact area between the belts 21 and 31. Besides, the waving of the belt 31 is prevented from occurring by a waving prevention member 35 and an air gap is prevented from being formed between the belts 21 and 31. Then, transfer dust is prevented from being generated and stuck to the transfer material 7.
