IPC: H04Q1/24
Filed: 1991-01-18
Abstract: PURPOSE:To simplify the test by converting a digital signal into an analog signal and comparing the converted analog signal with an original analog signal. CONSTITUTION:An analog signal from a signal generator 4 is digitized by an A/D converter in a PCM CODEC 1, reciprocated between PCM CODECs 1, 2 in a form of a digital signal and converted again into an analog signal by the PCM CODEC 1. Thus, an output of the PCM CODEC 1 is compared with an output of the signal generator 4 in a comparator circuit 5 to test the operation of a time switch 3. Thus, the test of the time switch in an electronic exchange is simplified and the time switch is easily connected to any PCM CODEC and the time switch is tested as to an optional reciprocating path in the electronic exchange.

Title: Data highway device
Inventor: YAMAGUCHI HITOSHI
IPC: H04L12/437
Filed: 1984-02-02
Abstract: PURPOSE:To inform quickly the search for a faulty station even in a double fault mode among plural slave stations by replacing the data received by a signal line with the reception data to be sent to a loop-back line by a slave station which received a loop-back command from a master station. CONSTITUTION:A master station #1 and slave stations #2-#n are connected in a loop from to a transmission line containing a signal line l1 and a loop-back line l2 through which signals are sent in the different directions. Then data are transmitted among these master and slave stations. The station #1 transmits the same signal to both lines l1 and l2. When a loop synchronizing control part 7 of the station #1 detects a fault of the line l1, the address of a slave station to be looped back is transmitted together with a loop-back command signal. A loop- back control part 5 of a slave station which received said command signal converts the signal sent from the line l2 into a digital signal by a signal converter 4 in place of the signal sent from the line l1. This digital signal is sent to the line l1 via a signal converter 3 in the form of the reception data. Then a data highway loop is formed. The loop-back command is sent successively to slave stations to secure a quick search for a fault even in a double fault mode.

Inventor: TAKEDA TAKESHI
IPC: G11B7/24073
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To achieve high density recording without causing increase in cost by detecting a guide means for continuously regulating an elliptic recording track position on an optical recording medium by generating change in the intensity of reflected light, and scanning the elliptic recording track, based on the detected guide means. SOLUTION: A circle 3 is a rotary locus of a radius R centering a rotation center C of a rotary optical part, and the rotary optical part rotates in the rotary scanning direction shown by an arrow. In that case, the locus of the rotary optical part rotates away from the recording track 2 by a distance Δaccording to a rotary angle. Here, while performing the focus control, the distance Δ is followed up by tracking control. Thus, the recording track 2 on the optical recording medium 1 becomes an elliptic arc, and it is possible to make a track pitch smaller than the one when the track pitch is a circular arc, and to obtain an optical recording medium 1 of a large capacity without influence by the crosstalk from adjacent tracks.

Title: Detecting device for shortage of refrigerant in refrigerating plant for vehicle
Inventor: INAZU HIROSHI
IPC: F25B49/02
Filed: 1991-02-08
Abstract: PURPOSE:To prevent positively a lack of lubrication in a compressor or a lack of cooling or heating capability by a method wherein an early sensing of a lack of refrigerant is enabled. CONSTITUTION:A lower pressure in a low pressure passage ranging from an outlet of an adjusting device 4 to an inlet port of a compressor 1 is detected by a pressure sensor 6, the number of rotation of a compressor 1 is detected by a sensor 8 for sensing the number of rotation and it is judged as a shortage of refrigerant when a lower pressure in the low pressure passage and the number of rotation of the compressor 1 are concurrently less than each of predetermined levels under an operation of a controller 7. With such an arrangement, an influence from a variation in the surrounding air temperature is relatively lighter at the lower pressure than at a higher pressure, resulting in that a shortage of refrigerant can be judged at an early stage. When the compressor 1 shows a higher number of rotation, a higher degree of lowering the lower pressure is attained, so that the judgement may not be carried out.
