Title: Assembling method of speaker
Inventor: FUKUTAKA EITAROU
IPC: H04R9/00
Filed: 1984-04-03
Abstract: PURPOSE:To enable the assembly of a speaker in a short time by utilizing liquid composites with electron beam hardenability for bonding a vibrating part or an outer periphery and by hardening and bonding it with the radiation of incident electron beams. CONSTITUTION:A liquid composite having a viscosity more than 0.5 milion cps at a room temperature is heated so as to lower the viscosity below 0.1 milion cps. After it is applied to a bonding part, it is pressed. After it is held by stickiness, it is hardened with the radiation of incident electron beams. For instance, if the liquid composite is heated and applied to a metallic frame, the composite is quickly cooled due to the difference of heat capacity and returns at about a room temperature. Thus, when a joint of a damper on the frame of a speaker and a cone edge is coated with an adhesive having such a liquid composite, the speaker can be assembled in a short time.

Abstract: PURPOSE:In single face wrapping method of a semiconductor wafer, to obtain a wafer having required finish thickness by sticking a detection chip to a sticking plate adhered with wafer thereby detecting the work completion time point reliably. CONSTITUTION:When wrapping, a plurality of wafers 17 are adhered to the lower face of a sticking plate 7 to rotate said plate 7 through a wrap 13 while to perform wrapping work onto the wafer 17 through a wrap 13.

Title: Telephone system
Inventor: INOMATA SHUNJI
IPC: H04Q3/58
Filed: 1987-03-19
Abstract: PURPOSE:To prevent a call from being connected with a subscriber which is different from that connected before disconnection of power supply when the power supply is disconnected, by controlling a switch so that a terminal can be directly connected with a prescribed circuit after a prescribed time, during which the circuit is restored, after the disconnection. CONSTITUTION:When power supply is disconnected, a switch network 6 is restored and a state where clear-back operations are made from key telephone sets 2 and 3 is set. On the network side, this state is detected and trank lines 4 and 5 are restored (set to disconnected states). At a control section 100, across which no voltage is applied from a power supply terminal 14, an electric current is made to flow to a coil 15 by the discharge from a capacitor 12 and switches 7A and 7B are held in states where they are set to contacts (b) side. After the trunk lines 4 and 5 are restored, the electric charges of the capacitor 12 disappear and the switches 7A and 7B are set to contacts (a) side. As a result, the key telephone set 2 is directly connected with the main wire 4 and the key telephone set 3 is directly connected with the trunk line 5. However, since the trunk lines 4 and 5 are already restored, talking partners are not exchanged with each other.

Abstract: PURPOSE:To measure insulation resistance without working the neutral point of a grounding transformer by connecting the ground resistance of the intermediate metallic layer of the case of a cable shield layer or electric equipment to reference resistance and thus forming a bridge circuit. CONSTITUTION:The layer consisting of an insulating layer 24 - an intermediate metallic layer 20 - an insulating layer 28 is provided between the cable shield layer 16 and an iron wire armor 26 in case of a submarine cable.

Then a variable voltage source 84 is adjusted so that a bridge balance voltage detecting meter 88 indicates zero, thereby canceling a noise voltage developed across a resistance 82 for detection. Then a switch 78 is closed to apply a voltage to the bridge circuit and a proportional resistance 72 and an adding/subtracting resistance 74 are adjusted so that the bridge balance voltage detecting meter 88 indicates zero, thereby finding insulation resistance RX 40.

After completing the recording of the variable information into the variable regions EA1, EA2, the characteristic data of the two pieces of the variable information in the variable region EA1 is obtained, and determined whether or not to coincide with the respective characteristic data contained in the variable information in the variable region EA2. Thus, it is discriminated whether or not the characteristic data obtained for the variable information which has not been recorded and updated coincides with those obtained when the card was inserted.

Title: Fuel cell
Inventor: IYASU KIYOTARO
IPC: H01M8/02
Filed: 1985-04-01
Abstract: PURPOSE:To maintain stable performance of a fuel cell over a long period by using a thermoplastic resin film in each rib electrode so as to prevent its warping. CONSTITUTION:A thermoplastic resin film 4 is heated and pressed into a peripheral region in the end section 2a of the rib electrode 2 of each cell unit to form a gas seal section having an I-shaped cross section. Due to the I-shaped cross section, this gas seal section has minimal stress concentration and therefore warping of the rib electrode 2 is almost prevented as compared to the conventional rib electrode thereby maintaining stable performance over a long period. Since the film 4 does not protrude from the end surface of the electrode base as distinct from the conventional method of directly sealing the end surface, rib electrodes 2 can be easily stacked together.

Abstract: PROBLEM TO BE SOLVED: To remove toner or dust from a discharging needle while always keeping the discharge state of the discharging needle stable without damaging the tip of the discharging needle by providing a discharging needle cleaning means for cleaning the discharging needle in non-contact with the discharging needle. SOLUTION: A flapper 58 turning in a direction shown by an arrow D centering a rotary shaft 58a between a position shown by a solid line and a position shown by a broken line is arranged at the exit 56b of a duct 56. When the flapper 58 is at the position shown by the broken line, the exit 56b of the duct 56 is closed. In the case of cleaning the discharging needle 36, the flapper 58 is set at the position shown by the solid line, the exit 56b of the duct 56 is opened, and a suction fan 60 is rotated. Thus, the toner or the dust fallen or stuck to the needle 36 is scavenged by a filter 62 through a through-hole 54 and the duct 56. Therefore, a member for cleaning the needle 36 does not come in contact with the needle 36, so that the tip part 36a of the needle 36 is not damaged, and the discharge state of the needle 36 is always kept stable.

Abstract: PURPOSE:To reduce the quantity of necessary ions for channel cut by deeply diffusing impurity ions injected for the channel cut by a heat treatment prior to the step of oxidizing a field when manufacturing an MOS semiconductor device. CONSTITUTION:An oxidized silicon layer 2 is formed on an N type silicon substrate 1 on which a P type well 4 is formed, for example, in a complementary MOS semiconductor device, and a nitrided silicon layer 3 becoming a mask upon injection of ions is selectively covered on the layer 2. Then, impurity ions for channel cut are injected to form a P<+> type region 5 and an N<+> type region 6. In this case, the suitable amount of impurity ions are 1X10<13>pieces/cm<3> for the P type region and are 3X10<12>pieces/cm<3> for the N<+> type region. Thereafter, the impurity is annealed in  nitrogen gas of 1 atm for approx. 15min. to deeply diffuse the thus injected impuriy  ions. Thus, it can reduce the quantity of necessary impurity ions for the channel  cut, and can prevent the occurrence of a stacking fault in the subsequent field  oxidation.
