Title: Communication controller
Inventor: IDE MIKIO
Filed: 1985-05-09
Abstract: PURPOSE:To improve the utilizing efficiency of a communication line by providing two back-off setting devices with different back-off time. CONSTITUTION:When a reception end signal 19 is outputted from a transmission/ reception circuit 4 to a host computer 3 at the end of reception, an FF 22 is set, and its output 23 brings a back-off setting device 21 in the permitting state and an output 24 brings a back-off setting device 9 into the unpermitting state, and a back-off setting value set by the back-off setting device 21 is inputted to a comparator 8. Since the back-off setting value of the setting device 21 is set shorter than that of a back-off setting device 9, the right of use of a communication line 1 is acquired easily just after the end of reception. When the transmission is finished, a transmission end signal 18 is sent from a transmission/reception circuit 4 to the host computer 3, the FF 22 is reset, the outputs 23,24 are inverted and the back-off setting device 9 to which a substantial back-off time is set is used.

Abstract: PURPOSE:To obtain a sensor which can be used for various measurements, by providing a substrate having a recessed part, a filmy body having a flexibility, and a means for storing physically or chemically a contact area of the filmy body and the bottom face of the recessed part. CONSTITUTION:When a filmy body 3 receives pressure, it is deformed downward in accordance with magnitude of its pressure, and a part of an adhesive layer 4 contacts a recessed part bottom face 6. Also, even when the pressure has been eliminated, a state that a part of the filmy body 4 remains sticking to the recessed part bottom face 6 is maintained by the adhesive layer 4. When the state is seen from the bottom face side of a glass substrate 1, a contact area part 7 to the recessed part bottom face t is visible through the glass substrate 1, and other part is invisible. In this way, by reading the quantity of this contact area part 7 by a scale 8, magnitude of the external pressure which the filmy body 3 has received can be measured.

IPC: H01L23/50
Filed: 1999-04-06
Abstract: PROBLEM TO BE SOLVED: To obtain a lead frame which can prevent damage such as cracks in bent parts of leads when the leads are bent. SOLUTION: A lead frame 30 for a surface mounting IC package has the same structure as a prior art lead frame except for provision of grooves 34 and 36 in all leads 32. The grooves 34 and 36 are made in the leads 32 at positions as fulcra at which lead bending is to be done. The grooves 34 are made in the leads so as to be open downwardly at positions immediately outside of a boundary line 18 of a resin sealing region, while the grooves 36 are open upwardly at positions outside of the grooves 34. The grooves 34 and 36 have a U-shape made by chemically etching the leads. The grooves 34 and 36 have a depth of from 1/3 or more to 1/2 or less a thickness t of the leads.  When this lead frame is used for the surface mounting IC package and the leads are bent, the effect of provision of the grooves causes bents having no damage such as cracks formed in two bent formation regions of the leads.

Abstract: PROBLEM TO BE SOLVED: To immediately release the locked condition of a rotor by arranging around the periphery of a coil spring, a cylindrical body which is brought in contact with the coil spring in its locking released condition and regulates the enlarging rate of the coil spring while being opposed to the coil spring in its locked condition having a clearance. SOLUTION: When pushing/pressing force F is applied to a cover wall 17 on the periphery of a cylindrical body 15A, the cylindrical body 15A is rotated in the same direction while being slid on a circular arc guide surface 19a. At the same time, the other end 4b of a twist coil spring 4 is also rotated in the same direction by the same distance so as to be enlarged and displaced, however, only a narrow clearance is sectioned between the cylindrical body 15A and the twist coil spring 4, therefore a first coil continued to the other end 4b is immediately brought in pressure contact with the inner circumferential surface of the cylindrical body 15A so that the twist coil spring 4 is regulated not to be enlarged any more.  Hereupon, the enlarging phenomenon of this first coil is sequentially and rapidly transmitted to one end 4a side being a fixed end through a second coil..., therefore the locked condition of a rotor 2 is immediately released.
