Title: Information recording and reproducing device
Inventor: NAKAMURA KIMIO
IPC: G11B9/14
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To realize a light weight and highly accurate head-medium distance control head by measuring the contact time between the cantilever provided on a head part and the projected part provided on the surface of a recording medium and detecting the distance between the head and the recording medium. SOLUTION: A recording and reproducing head 1 is arranged by being faced to a recording medium. Projected parts 7 are provided on one part of the surface of the recording medium and also two cantilevers 2, 3 are mounted on the head 1 and the cantilever 3 is made contactable with the projected parts 7. When the head 1 is scanned in the horizontal direction, the distance control cantilever 3 is brought into contact with the slope 11 of the projected part 7 and this contact continues until it passes the part 7. At this point, an energizing current 13 is detected in between the cantilever 3 and an electric layer and a distance from a detecting needle to the medium is calculated from an energizing time.  Thus, the head-medium distance is substantially controlled constant by controlling the height of the head 1 with respect to the surface of the medium so that the contact time between the lever 3 and the part 7 becomes constant.

Title: Bipolar transistor
Inventor: FURUKAWA AKIO
IPC: H01L29/73
Filed: 1989-05-15
Abstract: PURPOSE:To make it possible to improve significantly the operating speed of a bipolar transistor by a method wherein in the heterojunction bipolar transistor, in case a GaSb substrate is used as the substrate of the bipolar transistor, InXGa1-XSb with the condition that X is in a specified range is used as the material for the base layer of the bipolar transistor. CONSTITUTION:A bipolar transistor has a substrate consisting of GaSb and a base layer consisting of InXGa1-XSb (X=0.05 to 0.2). By using the InXGa1-XSb as the material for the base layer like this, a higherspeed bipolar transistor can be manufactured compared to conventional bipolar transistors of both of an N-P-N-type and a P-N-P-type. In particular, a speedup which is 10 times or faster can be expected to an N-P-N-type bipolar transistor which is manufactured by this method. Thereby, the operating speed of a bipolar transistor can be significantly improved.

Abstract: PURPOSE:To decrease the number of trunk circuits and to simplify the constitution of a service incoming connection system, by providing a function to send identifying information to a preceding exchange via a signal circuit when an incoming call to a subscriber exchange is detected. CONSTITUTION:When an incoming trunk 10 has an incoming call to a subscriber exchange 1, this call is given to an incoming trunk 3 to start a connection marker 5. When it is decided that an incoming subscriber is equal to a registered subscriber for the substitute answer service or the transfer service, the connection control to the subscriber for restoration is omitted. While a monitor device 6 extracts the incoming trunk identifying information and the incoming subscriber number for the marker 5 and sends them to a signal device 7 via a signal circuit 30. A trunk exchange 2 receives the information through the device 7 and catches an outgoing trunk 9 and connects the trunk 10 to an answer trunk 12 when a call is equal to the call received by the trunk 10. Thus the substitute service and the transfer service are carried out through the answer trunk 2 and an outgoing trunk 11 respectively.
