Title: Afc circuit of fm receiver
Inventor: TATEISHI MICHIHIRO
IPC: H03J7/08
Filed: 1978-06-14
Abstract: PURPOSE:To improve the frequency holding range of an AFC circuit by adding a simple circuit to the AFC circuit. CONSTITUTION:Demodulation signals and a DC voltage proportional to detuning are outputted from FM detector 4. These signals are caused to pass through a LPF consisting of resistance 10 and capacities 8 and 9, and only the DC voltage is taken out to feed back negatively the AFC voltage, which is applied to the varactor diode of local oscillator 5, to amplifier 1. Meanwhile, by applying the electronic tuning voltage to the base of transistor 12 from frequency control circuit 6, the collector resistance of transistor 12 is changed to control the feedback quantity of AFC, and the feedback quantity is reduced when the tuning frequency becomes high, thereby making the holding range narrow. When transistor 12 is operated in a sufficient linear region, the holding range becomes fixed.

Abstract: PROBLEM TO BE SOLVED: To improve both physical and appearance characteristics of a speaker diaphragm, without increasing its production cost by adding a specific amount of an inorganic or organic filler into resin, including a foaming agent of the loudspeaker diaphragm using an injected foam molding matter. SOLUTION: For a speaker diaphragm 1 using an injected foam molding matter, a resin mixture agent obtained by adding a foaming agent to polypropylene(PP) is injected into a metallic mold and then immediately the metallic mold is moved back and foamed. Thus, the inside of the metallic mold is foamed, and a foaming layer 3 is formed. A skin layer 2 which is not foamed yet since it is hardened before the foaming is formed on each surface of the layer 3 and this surface touches the inner surface of the metallic mold, while the resin is made to obtain a three-layer structure. This resin mixture agent includes 3 to 30 wt.% inorganic or organic filler. Thus, the surface thickness is increased with low specific gravity, and accordingly the light and highly rigid diaphragm 1 is obtained. Furthermore, the diaphragm 1 excels in the environmental characteristic and moreover is able to reduce its production cost, since no adhesion is required for three layers.

Title: Positioning apparatus
Inventor: AKIYAMA YUKIHARU
IPC: H01L21/60
Filed: 1987-03-27
Abstract: PURPOSE:To improve the operating efficiency of a moving table in a positioning technique by operating the moving table by a driving source generating heat at the time of drive and positioning the moving table and keeping the temperature of the table, the temperature of which is elevated by the reception of heat from the driving source on operation thereof, even at the time of the stoppage of the table. CONSTITUTION:When the supply of power to a motor 12 is started, the quantity of thermal deformation of an X table 6, etc. gradually increases with time, takes approximately a fixed value at the time of A, and subsequently displays a stable value. Consequently, since the thermal deformation of each member is stopped at the time of A, position coordinates determined, using the quantity of thermal deformation at the time of A as a reference are input to a position setting section 18, thus accurately positioning subsequent wire bonding. Since work regarding the products of one lot section is often stopped temporarily after the work is completed in actual wire bonding work, the motor 12 is non- load driven in order to elevate the temperature of the X table 6 up to the same temperature as at the time of A again. Accordingly, the lowering of the temperature of the X table 6 can be prevented effectively.
