Abstract: Described herein is the converting between a component SDI signal D1 and a composite SDI signal D2. A single memory is prepared. Further, the corresponding signal is written into the memory in accordance with a clock corresponding to a transfer rate of the SDI signal D1 and the corresponding signal is read from the memory in accordance with a clock corresponding to a transfer rate of the SDI signal D2. The digital signal read from the memory is re-distributed based on header information added to the SDI signal D2. Pieces of header information (ADF, DID, DBN, DC and CS) corresponding to conversion modes are added to the outputted digital signal. Thus, the cost down to the signal converting can be achieved by providing a single signal conversion memory alone and reducing signal conversion memories and their peripheral circuits.

Abstract: A sample apparatus includes a sampling valve having a sample inlet through which a sample such as urine is introduced from the outside of the sampling valve to the inside thereof; a sample outlet through which the sample is sent from the inside of the sampling valve to the outside thereof; and a sampling passage for setting apart a predetermined amount of the sample between the sample inlet and sample outlet. It further includes a first electrode section located close to the sample inlet so that the sample can come into contact with the first electrode section, a second electrode section located close to the sample outlet so that the sample can come into contact with the second electrode section, and a sensor circuit for measuring the impedance between the first and second electrode sections and for using the measured impedance to determine whether or not the sampling passage contains a predetermined amount of the sample.

Abstract: A machine part comprises: a base part formed of a titanium alloy or an aluminum alloy and having a roughened surface of Ra 0.5 .mu.m or above and PPI.sub.50 or above; and a Ni--P electrodeposit layer formed over the surface of the base part by an electroplating process using a Ni--P plating bath containing a stress relaxing agent, and having a stress of 20 kgf/mm.sup.2 or below. The machine part has a small specific gravity, excellent seizure resistance, wear resistance and fatigue strength.

Abstract: A matrix switching apparatus includes a plurality of switching units connected in tandem, each switching unit having a plurality of input terminals and a plurality of output terminals. There are a plurality of transmission/reception units, each provided within a respective switching unit and also within a remote control unit. The transmission/reception units are for transmitting switching data. A first one of the transmission/reception units is set to a master station mode and sequentially polls the remaining transmission/reception units which are set to a slave station mode. The remaining units respond to the polling by outputting switching data, which is collectively transmitted by the master station over a serial busline. The remaining transmission/reception units receive only relevant data from the switching data transmitted over the serial busline and supply the relevant data to controlling units which control the turning on and off of crosspoint switches in the switching units.

Abstract: Zn-Mg alloy is plated by vapor deposition on the surface of metals. Since Zn and Mg are vapor-deposited as a vapor mixture of an optional ratio on the surface of metals, plated layers of excellent corrosion resistance, peeling resistance of coating film, formability, etc. can be formed. There is disclosed a method of forming uniform vapor mixtures of Zn and Mg, and vapor-depositing them on the surface of metals as the method forming the vapor-deposited layers.

Abstract: Provided herein is an Al-Cr alloy vapor deposited product having high corrosion resistance which can be used under a corrosive environment for a long period of time on account of the outstanding corrosion resistance and heat resistance of the Al-Cr alloy vapor deposited layer.
