Title: Defocusing detector
Inventor: KINOSHITA TAKAO
IPC: G03B17/20
Filed: 1981-06-30
Abstract: PURPOSE:To accomplish the decision of focusing and the detection of image defocusing with the same device by detecting the image defocusing from an output of a photoelectric transducer in a focusing position detecting device by using  the variation of focus signals. CONSTITUTION:A focus signal of a central sensor is stored in a sample holding circuit 14b and compared with the focus signal of 1 sequence ago which is stored in a sample holding circuit 200 and the difference is converted into an absolute value by an absolute value circuit 205. Said focus is converted at its impedance and divided by a variable resistor 204 and the divided signal is compared with said absolute value signal by a comparator 206. Consequently the ratio of the variation of a focus signal in one sequence to the focus (relative focus signal variation value) is decided and the existence of defocusing is displayed on an LED208.

Title: Vertical shaft type submerged pump device for liquified gas tank
Inventor: TAJIMA DAISAKU
IPC: F04D29/049
Filed: 1995-04-26
Abstract: PURPOSE: To increase the strength of a bearing for supporting a pump shaft in association with the displacement enlargement of a pump and the bore enlargement of a liquid lifting pipe. CONSTITUTION: The center bearing 15 of a submerged type vertical shaft pump is detached from the support of a pump shaft 12 by the action of a balancer 17 during the normal operation of the pump. Instead a static pressure bearing 19B supports the pump shaft 12. At the start time, not during the normal operation of the pump, thrust load is applied to the center bearing 15, and the burden of load becomes large, so that the service life of the bearing is shortened. As the center bearing 15, two single-row deep groove type ball bearings 15a, 15b are therefore arranged vertically along the longitudinal direction of the shaft 12, and a ring spacer 15c is interposed between them so as to form the deep groove type ball bearing 15 arranged in double rows.  Load F is dispersed equally to two single-row deep groove type ball bearings 15a, 15b, so that the strength of the center bearing 15 is increased.

IPC: H04R31/00
Filed: 1983-06-07
Abstract: PURPOSE:To obtain a thin, highly rigid diaphragm free from anisotropy by forming a diaphragm for a speaker made of reinforced synchetic resin by preheating and melting an pellet mixed with a filler to form by compression molding. CONSTITUTION:The pellet contained in a hopper 1 is molten in a heating cylinder 2 and led to a head 3.

Title: Coil for rotary electric machine
Inventor: FUJIOKA SHINEI
IPC: H02K3/34
Filed: 1980-07-28
Abstract: PURPOSE:To improve the wetness of resin and to prevent the flowage of resin, by a method wherein a slot liner is formed by applying thermal pressure bonding to aromatic polyimide paper and laminated mica, and the slot liner is wound around coil bodies by placing the laminated mica outside. CONSTITUTION:Aromatic polyimide paper 11 and laminated mica 12 are stacked and formed in a body by thermal pressure bonding to make a slot liner material 5.
