Title: Manufacture of aluminum nitride multilayer board
Inventor: KURIHARA KOICHIRO
IPC: H05K3/46
Filed: 1987-12-11
Abstract: PURPOSE:To acquire a multilayer wiring board having less warp or turbidity by mixing an organic binder and a burning assistant to aluminum nitride powders, by manufacturing a green sheet, by printing a desired wiring pattern thereon, and by carrying out debinder and sintering after laminating the sheet. CONSTITUTION:An organic binder is applied to powders made by mixing a burning assistant to aluminum nitride powders, a green sheet is manufactured by doctor blade method, and a through hole is formed thereto. After a conductor such as tungsten is printed to make a desired wiring pattern, the sheet is laminated. Then debinder is conducted in a mixture atmosphere consisting of nitride, hydrogen and water vapor. Sintering is carried out thereafter. According to this constitution, a wiring metal resists to oxidization and organic substances in the green sheet and paste are completely decomposed, thus remaining no carbon. When this laminate is sintered, it does not receive any detrimental effect because no carbon remains. A sintered body of high heat conductivity without warp or turbidity can be acquired in this way.

Title: Magnetic recording and reproducing device
Inventor: KAWACHI NOBUYOSHI
IPC: G11B5/027
Filed: 1988-12-14
Abstract: PURPOSE:To uniformize the output level of a voice reproducing signal and that of a tape address reproducing signal by providing a function to regenerate selectively a voice signal and a tape address signal on one track of a magnetic medium. CONSTITUTION:The tape address signal or the voice signal recorded on the magnetic medium is taken out by a reproducing head 1. When a signal amplified at an equalizer amplifier 2 at an initial stage is the tape address signal, it is switched to a side A at a two circuit/two-contact switch 3, and outputted from an output terminal 6 via a tape address system amplifier 4 and an output amplifier 5. Also, when a recorded signal is the voice signal recorded on the same track as that on which the tape address signal is recorded, the signal is taken out by the reproducing head 1, and amplified by the equalizer amplifier 2 at the initial stage. In other words, the signal larger than a reference level can be suppressed to the reference level by applying it on a limiter, and the signal smaller than the reference level is amplified. In such a manner, it is possible to uniformize the level of the voice reproducing signal and that of the tape address reproducing signal.

Title: Device and method for monitoring transmission error rate on transmission link, and device and method for controlling transmission link based on the rate
Inventor: DAGURASU SHII SHIYUMITSUTO
IPC: H04L69/40
Filed: 1993-11-22
Abstract: PURPOSE: To obtain the error rate monitor device which controls the transmission link safely and effectively, and its method. CONSTITUTION: An error rate monitor 101 monitors an error occurring to the transmission link 103 within a fixed time interval. If an error occurs within the time interval, one increment value is added to the count of a counter which is initialized in the beginning 0 and when no error occurs within the time interval, one decrement value is subtracted from the count (minimum value 0). The increment value and decrement value are determined as a congruence function of a reciprocal operation delay time on the link, a maximum permissible transmission error rate on the link and the speed (c) of the link and both the values are generally different. When the count exceeds a given threshold value T, switching is declared.  The threshold value T is determined as a congruence function of the maximum value of messages stored in a transmitting buffer at the time of the switching, the maximum permissible transmission error rate on the link, and the length of the fixed time interval.

When the designated expansion method is stored in the TTI function information storage section 101, picture data of an original are read from a scanner (not shown) to a bit map memory 102, an expansion section 103 extracts the TTI function information from the storage section 101 to expand the TTI function information from the expansion start position to the memory 102 according to the stored expansion method. Thus, when the TTI function information is in use, it is avoided that part of the content of a transmission original is not delivered to a transmission destination. Furthermore, the TTI function information is made easily readable.

Abstract: PURPOSE:To unnecessitate preparing plural masks whose mask pitches are different by changing the thickness of the electrode film of a resonator constituted of a substrate/electrode/dielectric. CONSTITUTION:A surface acoustic wave resonator is constituted of the substrate/driving electrode and reflector/dielectric film. The frequency adjustable range B of (thickness of the electrode film)/(wavelength) at which the frequency which is higher than the desired frequency can be obtained is searched within the range of (thickness of the electrode film)/(wavelength) in a resonator stabilizing area A. Then, the electrode film of the thickness of the film in this range B is deposited, patterning is executed then the dielectric film whose sound speed is slower than that of the substrate is formed, and oscillated. An another dielectric film which is thinner than the above mentioned dielectric film is deposited, and the oscillation frequency is decreased, so that the oscillation frequency can have the thickness of the film corresponding to the degree larger than a prescribed value, and the prescribed surface acoustic wave resonator is obtained. Thus, it is possible to omit the process of forming the plural masks, changing the electrode pitches, and correcting the oscillation frequency.
