Title: Inter-lan bridge device
Inventor: TSUTSUI HIDEKAZU
IPC: H04L12/46
Filed: 1988-11-14
Abstract: PURPOSE:To prevent the reduction of the transmission speed of a broadcasting frame and to automatically restart the operation of an input output port by performing a transceiver return test with an input/output port, logically separating and obtaining an operation condition. CONSTITUTION:By the return test instruction from a main control processor 3, a return control part 1-1 of an input output port 1 performs the transceiver return test and a comparing part 1-2 compares the data sent to a transceiver 2 with the returned data. Next, when the condition (collision error) in which the compared result is non-coincident and the instructed port 1 cannot be used, is detected, or when the collision error is detected during the operation, a collision error detecting part 1-3 returns the effect to the processor 3. The port 1 is logically separated, and the transmission instruction of a frame, etc., is given only to other normal port 1. Thus, the reduction of the transmission speed of the broadcasting frame is prevented, and the operation of the logically separated port 1 can automatically be restarted when the return test is OKed.

Filed: 1986-12-03
Abstract: PURPOSE:To block an external electric field from infiltrating into an impurity region and thereby to prevent the relative precision from degrading between the resistance values of resistance elements by a method wherein electrode wires are designed to cover their own impurity regions through the intermediary of insulating films. CONSTITUTION:An electrode wire 25 at an end of a p-type region 19 is connected also to an n-type layer 16 through the intermediary of an n-type region 21. An electrode wire 26 at the other end of the p-type region 19 is allowed to cover the p-type region 19 through the intermediary of an SiO2 film 23. Here, the resistance length is represented by (l) and the length of coverage on the p-type region 19 provided by the electrode wire 26 is represented by l1. In a similar way, an electrode wire 27 at an end of a p-type region 20 is connected to an n-type layer 17 and an electrode wire 28 at the other end is allowed to cover the p-type region 20 by a length l1. With the electrode wires 25 and 27 being connected to the insular n-type layers 16 and 17, difference in back bias effect is prevented from emerging between the resistance elements. Difference in resistance to be created by an external electric field may be suppressed because the electrode wires 26 and 28 block such a field from infiltrating into the p-type regions 19 and 20.

Title: Controller for data reproducing pll circuit
Inventor: HAYASHI YASUHIRO
IPC: G11B20/10
Filed: 1993-11-17
Abstract: PURPOSE:To accelerate search operation by controlling a data reproducing PLL circuit to enter no dead band controlled from neither a phase comparison result nor a frequency detection result. CONSTITUTION:By successively heightening an oscillation frequency of a voltage control oscillator VCO, the 11T-0.5T (T is period) of a phase clock PLCK is driven into so as to enter a polality inversion interval of an EFM (8 for 14 modulation) signals obtained from a data slice circuit. In such a case, the control heightening the oscillation frequency of the oscillator VCO is performed continuously even when entering a capture range by the control of only a phase comparison circuit. Then, when the 11T+0.5T of the phase clock PLCK enters the polarity inversion interval of the EFM signal, the control heightening the oscillation frequency of the oscillator VCO is stopped by a numeral B outputted from a maximum length register 27. Thus, the dead band from the phase comparison circuit and the frequency detection circuit 22 is eliminated by the data reproducing PLL circuit.

Title: Method for controlling temperature of mold of resin molding apparatus
Inventor: NAGASAWA MASATO
IPC: B29C33/02
Filed: 1989-11-06
Abstract: PURPOSE:To make it possible to mold a normal product as soon as a molding operation is started or restarted by controlling set temperatures so that said set temperatures become higher than those in normal operation when such state is detected, in which a molding operation is suspended with a mold opened. CONSTITUTION:When a molding operation is suspended with a mold 18 opened, set temperatures are kept at higher temperature, so that temperatures A at detecting point during th suspension of operation with the mold opened become higher in comparison with those during operation. Therefore, when the operation is suspended, although radiation from the surfaces of the mold is large, surface temperatures B can be prevented from falling down, so that the temperatures B can be held at temperatures nearly suitable for molding both in operation and out of operation. Even when operation is suspended with the mold closed, temperature of the mold is controlled taking account of the radiation from the surfaces thereof, hence the temperatures B can be held at temperatures suitable for molding.
