Abstract: PURPOSE:To facilitate the preservation of an IC package and to shorten a line distance between IC packages and a delay time by a method wherein the terminal sections of the IC package are made to be through-holes which break through the IC package from its upper side to lower side and a socket is formed into pin shape. CONSTITUTION:The preservation of only an IC package is facilitated by making terminals 101 of the IC package 100 through-holes, and the IC package is mounted on a board 1 in such a manner that terminals 201 of a socket 200 are formed into pin shape and the terminals 201 of the socket 200 are inserted into the IC package 100. And, when the IC package 100 is mounted holding the pins of the socket 200, a soldering may be made to fix the IC package 100. If the length of the terminals 201 is long enough, the IC packages 100 can be mounted as they are heaped up, and a terminal line distance between the package can be shortened by these processes, consequently a delay time occurring during the transmission of information can be shortened.

Title: Circuit built-in photodetector
Inventor: KUBO MASARU
IPC: H01L27/14
Filed: 1991-07-23
Abstract: PURPOSE:To speed up a photodetector division by specifying the thickness and the resistivity of an N-type resistance epitaxial layer. CONSTITUTION:The width of a depletion layer is Xd; the thickness of an undepleted epitaxial layer is W; and the distance of carriers running through an N<+> type buried diffusion layer 2 is Xsb. At this time, a cutoff frequency corresponding to a response speed of a photodiode is expressed by a formula I. A parameter which can be designed by the third term is W. W can be zeroized by making the thickness of a high-resistivity epitaxial layer 10 of a completed photodiode equal to or less than the width of a depletion layer by a reverse bias impressed on the photodiode. The cutoff frequency F3db of a photodiode so designed as to satisfy the condition of the third term can be expressed by a formula II. Therefore, it is necessary that the thickness of the N-type high-resistivity epitaxial layer is 8-14 microns, and the resistivity 10OMEGAcm or less.

Abstract: PURPOSE:To heighten the accuracy of the number of revolutions of a rotor by controlling the revolution of the rotor with a magnetic sensor fitted to the rotor. CONSTITUTION:A rotor 109 has magnets 110, 111 at locations point-symmetric to each other. When a magnet 110 is above a magnetic sensor 101, a circuit becomes an ON state, a current flows in a coil 108, and the magnet 111 is attracted.

Title: Method of controlling blower
Inventor: YAMAMOTO KUNIHIKO
IPC: F04D27/02
Filed: 1982-10-19
Abstract: PURPOSE:To eliminate useless consumption of energy while preventing surging by turning on and off a wind releasing valve in response to discharge wind pressure while operating a static blade to throttle its angle so that wind pressure control is interlocked with wind amount control. CONSTITUTION:When a wind pressure point is raised abruptly to a point P' on a surging preventing line Pa, a surging control unit 11 opens a wind releasing valve 9a to emit a portion of sent wind to the atmosphere. Thus, the wind pressure point is lowered to move from the point P' to a point R on a surging preliminary line Ra. Thus, the surging control unit 11 closes the wind releasing valve 9a to throttle an angle of static blade 2a of a static blade varying unit 7. Hence, the discharge wind amount of a blower 2 is reduced to move the wind pressure point to the point P' on the surging preventing line Pa. Thus, the surging control unit 11 controls the wind pressure and the wing amount in relation to each other.
