And, it is disposed so as to be turnable with the tape guide driving members 31 and 33 around a tape drum 2 in the higher position than the lower end of the tape guide in its final loading position. Then, an arm member for moving a pinch roller 8 is extended across a turning locus of the cam member 34 from the outside to the inside, and the arm member is engaged with a tip part of the cam member 34. By such a method of constitution, a plane area of the device can be minimized enough, and thin formation of the device is realized.

Title: Communication system
Inventor: OSHIMA IZUMI
IPC: H04L12/40
Filed: 1989-08-08
Abstract: PURPOSE:To shorten a time required for returning a status by providing a simultaneous transmission control part, and returning the status by one communication frame at each communication equipment for the transmission request of the status from a home bus controller to each communication equipment. CONSTITUTION:The communication equipment 2a inputs the communication frame from an input terminal 4 of a home bus and outputs it to a CPU 6 and the simultaneous transmission control part 7. The simultaneous transmission control part 7 initializes a count value (i) to '0' and detects a start bit 20 of a data field 16. The count value (i) is compared with the address of the communication equipment 2a. When the count value is coincident with the address, the status is outputted from the CPU 6 to a driver 8 and sent out through an output terminal 9 to the home bus 3. The other communication equipments 2b,..., 2j are operated samely. Thus, the home bus controller 1 can know the status for the 10 communication equipments 2a, 2b,..., 2j by one communication frame.

Title: Production of thin-film magnetic disk
Inventor: MITSUYA HARUHITO
IPC: G11B5/84
Filed: 1993-08-20
Abstract: PURPOSE:To prevent the abnormal growth of a magnetic film by removal of crystal defects by selectively removing the crystal defective parts on the surface generated at the time of a texturing treatment by an etching liquid while allowing the non-crystal defective parts to remain. CONSTITUTION:The crystal defects 6 are generated when a substrate 1 plated with Ni-P is subjected to texturing. This substrate 1 is immersed into an etching liquid to form a complex which is alkaline and consists of Ni as a central atom. The crystal defects 6 are then conceived to be more activated than in the parts where the defects are not generated and immersion progresses more in the crystal defects 6 than in the other parts. The shape of macroscopic ruggedness formed by finishing with a polishing tape remains as it is and only the crystal defects are selectively removed in such a manner that the parts of valleys concentrated with the crystal defects are made deep in microscopic view. The influence of the crystal defects is suppressed and the abnormal growth, etc., of the magnetic film is prevented by the removal of the crystal defects.

Title: Asynchronous communication control circuit
Inventor: TATENO MINEO
IPC: G06F13/28
Filed: 1986-09-03
Abstract: PURPOSE:To avoid the erasion of communication data by holding a DMA request signal inputted during the forcible halt of a DMA controller until this controller becomes active. CONSTITUTION:A DMA request signal (b) outputted from a parallel port 1 is stored in a FF 20. When a DMA forcible halt signal (a) is turned off, an output signal (c) received from the FF 20 is outputted through a NAND gate 21 and an AND gate 22 as a DMA request signal to be applied to a DMA controller 3. While the controller 3 is set under halt state while the signal (a) is kept on and therefore no DMA request signal is accepted. When the signal (a) is changed to an OFF state from an ON state, the signal (a) stored in the FF 20 is outputted to the controller 3. Thus it is possible to receive and transfer data accurately and at a high speed in simple circuit constitution.

Filed: 1994-08-31
Abstract: PURPOSE: To obtain absorbing.shielding material of electromagnetic wave whose dielectric constant is larger than that of water, by using solid powder having large dielectric constant and water content mixed in the solid powder. CONSTITUTION: By mixing a kind of solid powder and water, the dielectric constant in the microwave region is increased two or more times as compared with the case of water only. For example, the dielectric constant in the case that carbon black is used as the solid powder becomes about 240-120, according to the concentration to water. That is about 3 times the dielectric constant of pure water. An object 5 to be shielded is completely surrounded by a double wall constituted of conductors 2, 3, and the part between them is filled with the solid powder/water mixture 1. If necessary, the conductor 3 is grounded by using an earth terminal 4. Electromagnetic noise traveling from the outside is shielded-absorbed by the wall, and does not practically permeate the inside, or remarkably atenuates and permeates.

Then, an optical element is controlled, the intensity distribution shape of light, for exposure, which is radiated from an effective light source is changed, and the above operation is repeated. Then, contrast curves regarding respective light-source shapes are drawn so as to be stored, the contrast curve in which a secondary peak does not exceed a slice level and in which a primary peak becomes maximum is selected out of them so as to be set as the optimum value of the optical intensity distribution of the effective light source.

Abstract: PURPOSE:To eliminate the need of balance adjustment in fitting a pointer to a turning axis by cutting out a weight for keeping the balance of the pointer from a steel rod in conformity with plate width corresponding to the weight of the pointer on the basis of a correlation between the aforesaid weight and plate width. CONSTITUTION:A microcomputer 102 calculates the plate width of a weight 6 corresponding to the weight of a luminous pointer 2 measured with this measurement instrument 101, on the basis of a correlation between the weight of the luminous pointer 2 and the plate width of the weight 6 preliminarily stored in a memory device 104, and controls a cutting device 103. This cutting device 103 cuts out the weight 6 from a deformed bar of rolled material to the calculated plate width. A retaining member 7 holds and fixes the weight 6 in the storage space 53 of a pointer cover 5. The predetermined shape of the retaining member 7 alone can be made to match, even if the plate width of the weight 6 changes variously, according to the weight of the luminous pointer 2.

Abstract: PURPOSE:To accelerate dewing and enhance efficiency in recovering latent heat, by a construction wherein the ratio of a heat-transmitting area on a combustion gas side and that on the circulating water side is gradually reduced from the upstream side to the downstream side of a combustion gas, and a passing area of the combustion gas is also gradually reduced. CONSTITUTION:The combustion gas is sequentially passed through a heat exchanger as indicated by arrows, while circulating water flows sequentially in the order of heat exchangers 12C, 12B and 12A. In the heat exchanger 12A comprising water-passing pipes 15 fitted with fins 14, the heat-transmitting area on the gas side is set to be about 10 times of that on the circulating water side, and the heat exchanger 12B is provided with annular finned water-passing pipes 16 having a gas-side heat-transmitting area of smaller than that of the fins 14, and the height and the pitch span of the fins are set to be so large that drops do not fill up the spaces between the fins. The heat exchanger 13C constituted of a bare pipes 17 has a reduced pitch and a restricted gas passage so that the area for contact of the gas becomes large and dewing occurs easily. Dewing is accelerated by removing sensitive heat of the combustion gas on the upstream side and removing latent heat of the gas on the downstream side.
