Title: Hybrid type dc switch
Inventor: KITAMURA TSUNEHIRO
IPC: H01H33/59
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a hybrid type dc switch in which the deterioration and the dispersion of shutoff performance are very little, and complete insulation can be conducted at the off time. SOLUTION: A switch with contact 1 turns main make and break contacts X1 , X2 on when a control signal INPUT inputted to a control signal input terminals I1 , I2 becomes 'H'. MOSFETs Q2 , Q3 conduct on-operation when the auxiliary make and break contact X3 of the switch with contact 1 is turned on delaying from the on-operation of the main make and break contacts X1 , X2 . Thereby, a dc power source DC is connected to a load 5 causing a load current to flow. When the control signal INPUT becomes 'L', the switch with contact 1 turns off the auxiliary make and break contact X3 first of all so as to turn off the MOSFETs Q2 , Q3 . The load current is broken by this off, and thereafter the main make and break contact X1 , X2 are brought into an off state. No arc is generated at this off time.

Title: Optical amplifier
Inventor: MASUDA KOJI
IPC: H04B10/29
Filed: 1989-04-28
Abstract: PURPOSE:To increase an allowable single transmittance total gain in an optical amplifier by a method wherein one piece or more of an optical isolator or optical isolators having no polarization dependency are arranged on an optical path near an emitting side optical connector or in the middle of the optical path between the emitting side optical connector and a rare earth element added optical fiber in the optical amplifier. CONSTITUTION:Signal light propagated to an optical waveguide 8 is introduced in an optical amplifier (a fiber luminous amplifier) 1 through an incident side optical connector 2 and is entered in a wave combining device 4. Then, the signal light and excitation light, which are combined by the device 4, are transmitted an optical isolator 10 in the forward direction and are entered in one end of a rare earth element added optical fiber 5. The fiber 5 is brought into an excitation state with an incidence of the excitation light and the signal light is subjected to amplification action. Then, the amplified signal light and the excitation light are transmitted an optical isolator 11 in the forward direction, are entered in a wave divider 6 and are divided. The divided signal light to be amplified by the amplifier is sent out to an optical waveguide 9 as the output of the amplifier 1 through an emitting side optical connector 7. Here, if the transmittivity in the forward direction of the isolators 10 and 11 and the transmittivity in the backward direction of the isolators 10 and 11 are respectively assumed to be [1] and [T], the intensities of reflected lights from the connectors 2 and 7 are reduced by T times. Thereby, a limitation on a single transmission total gain is relaxed and the optical amplifier, which is actuated at a high gain and stably, can be obtained.

IPC: B22C9/08
Filed: 1979-08-31
Abstract: PURPOSE: To prevent an ingate-broken portion from projecting and simplify the subsequent finishing process at the time of casting a circular casting by so setting a  mold that the excess metal portions connecting smoothly to the outside circumferential surface of the ingate-broken part of the casting are provided.  
     CONSTITUTION: A mold is made in such a manner that the excess metal portions 5, 5 continuous to the portion 4 where the ingate provided along the outside circumferential surface 3a of a circular casting 3 such as flywheel is broken are formed on both sides in the circumferential direction of the broken portion 4. Molten iron is cast in this mold to manufacture the circular casting 3. Here, the two excess metal portions 5, 5 are respectively longer than the width of the ingate, connect smoothly at both ends in the circumferential direction of the broken part 4, become gradually less in thickness as they go away circumferentially and finally become continuous to  the outside circumferential surface 3a of the circular casting 3; therefore, the  machining of the next outside circumferential face 3a may be smoothly performed.  Namely, there is no need for removing the broken part 4 of the ingate with a  grinder and necessary machining may be performed as cast, thus the finishing  process may be considerably simplified.
