Patent JP-S56149808-A (JP)
Title: Automatic gain controller of receiver
Inventor: SUGAZAKI HIDEO
IPC: H03G3/30
Filed: 1980-04-22
Abstract: PURPOSE:To prevent deterioration of characteristics caused by overload, etc. and also reject an abnormal oscillation, etc. caused by a strong antenna input, by stopping the amplifying operation of a transistor for amplification in accordance with an excessive level of an antenna input signal. CONSTITUTION:An input signal is high frequency-amplified by the transistor (TR) for amplification Q1 through the antenna circuit ATC from the antenna AT, and is sent to the intermediate frequency IF through the mixer MX. The collector and emitter of the TR for AGC Q2 are inserted between the base of the TR Q1 and ground. Also, the DC voltage which is IF-detected and is proportional to the antenna input is divided by resistances R4, R3, is smoothed by the capacitor C2, and after that, it is applied to the base of the TR Q2 through the resistance R2. When the antenna input is large, the degree of conduction of the TR Q2 becomes deep, and the amplifying operation of the TR Q1 is reduced. In the event of a strong antenna input, the TR Q1 conducts completely, and operation of the TR Q1 is stopped. In this case, the input signal level is attenuated remarkably and an abnormal oscillation, etc. are rejected.

Title: Machining method in variable tool diameter-type spindle device
Inventor: MORIKAWA TAKASHI
IPC: B23B29/034
Filed: 1983-03-31
Abstract: PURPOSE:To decrease the usage frequency of each tool tip and reduce the number of the tool replacement by constituting so as to use multiple tool tips with the radial distance from an outer spindle axis to the tool tip increased in sequence in response to the machined bore diameter. CONSTITUTION:A spindle device has a double structure, an inner spindle and an outer spindle; and the inner spindle is made eccentric in relation to the outer spindle by (e). Next, when theta is changed within a range 0<=theta<=pi, i.e., the inner spindle is rotated clockwise by theta and a tip 25a is shifted from a point P to a point P', this tip 25a is separated from the center O of the outer spindle following a locus B with the center E of the inner spindle serving as a center, thus the cutting radius R due to the tool tip 25a is gradually increased. Therefore, multiple tips of a tool A can be separately used in response to the machined bore diameter. Accordingly, the usage frequency of each tip is decreased and the number of the tool replacement is reduced.

Abstract: PURPOSE: To test a piece in a state proximate to a practical condition and precisely determine the quality of the piece, by providing a thermal module on a water absorber on the surface of the test piece to periodically change the surface temperature of the test piece.  
     CONSTITUTION: A test piece 1 of an inorganic wall surface material or an inorganic outside finish material such as a tile is immersed in water so that the test piece absorbs enough water. After that, the surface of the test piece is placed on a water absorber on a thermal module 3. The temperature difference between both the sides of the module is set at 60°C, for example. Air is supplied to radiation fins 4 by force to perform cooling. The temperature of the test piece 1 is thus periodically changed between a room level and a low level. Water absorption is caused at the room temperature to repeatedly perform testing to measure the number of times of freezing and melting of the test piece 1 until its cracking.
