IPC: B23H9/00
Filed: 1995-03-24
Abstract: PURPOSE: To always stably obtain a uniform surface reformed layer of fixed thickness by providing an ending discriminator of discriminating completing a remelting process from changing a machining speed obtained from a speedometer. CONSTITUTION: In a speedometer 22, from information of a machining position detected by a Z axis servo amplifier 21 during secondary machining treating, a corresponding amount to a machining speed relating to a machining surface is one by one continuously or intermittently calculated. That is, from a change amount of a machining position (machining depth) per prescribed time, that is, from the change amount, the machining speed is calculated. An ending discriminator 23 is previously given a speed value for discriminating ending, to discriminate ending a remelting process in the point of time the machining speed is in this value or less, and the secondary machining process is ended.  Timing of ending the remelting process can be surely further automatically decided without through labor, as a result to always stably obtain a uniform surface reformed layer of fixed thickness, also to enable treating efficiency to enhance by minimizing a machining time required for surface treating.

Filed: 1994-04-04
Abstract: PURPOSE:To reduce cost by arranging a plate like baffle whose window facing side has low emissivity on the opening part outer periphery of a cold shield and also a mask plate whose lens system side has high emissivity outside of a window of a Dewar. CONSTITUTION:A cold shield 7 having a plate-like baffle is arranged around an opening part, and a mask plate 11 having an opening part is provided.

Thus the vibration or oscillation can be eliminated to ensure a stable writing.

Title: Production of acrylamide polymer
Inventor: HONDA TADATOSHI
IPC: C08F2/10
Filed: 1980-05-21
Abstract: PURPOSE: To rapidly polymerize titled polymer useful as a papaer-strengthening agent, a polymer coagulating agent or the like, by purifying, by means of an ion exchange resin, an aqueous solution of crude acrylamide obtained by catalytically hydrating acrylonitrile in the presence of a copper-containing catalyst.  
     CONSTITUTION: An aqueous solution of crude acrylamide obtained by catalytically hydrating acrylonitrile in the presence of metallic copper or a metallic copper-containing catalyst, is passed sequentially through an H-type cation exchange resin layer, a weak acid salt type strong base anion exchange resin layer and an H-type weak acid cation exchange resin layer. Next, the treated solution is polymerized to produce an acrylamide dolymer. When the aqueous acrylamide solution subjected to the specified ion exchange resin treatment is used as a meterial, the rate of polymerization of the monomer becomes higher as compared with a case when acrylamide purified by recrystallization is used as a raw material. This difference in polymerization rate is distinct in case where a low-polymerization rate formulation is used.

Filed: 1990-03-19
Abstract: PURPOSE:To ensure an optical signal level at branching by measuring the delay time difference of optical signals between a tentative switching line and a main switching line and switching a main optical signal from the tentative switching line into the main switching line while synchronizing the optical signals. CONSTITUTION:A delay measuring section 31 measures the delay time difference of optical signals sent through an active line 1 and a tentative switching line 21 by electric signals from optical receivers 30a, 30b and inputs the result to a delay adjustment section 32. The adjustment section 32 adjusts the result of measurement of the measuring section 31 so as to be zero. Thus, an optical signal equivalent to the optical signal of the line 21 synchronously with the optical signal of the line 1 is outputted from an optical transmitter 33. The optical signal outputted from the optical transmitter 33 enters an optical branching coupler 10b and is coupled with the line 1 and sent to an active line 2b at the outside of the switching section. Then an optical connector mobile device 23 releases the connection between optical connector plugs 22a, 22b to open the line 1. The transmission line for the main optical signal is not interrupted by the operation and the line 1 is switched into the line 21.

Filed: 1994-04-05
Abstract: PURPOSE:To eliminate an ill condition causing a vehicle occupant to feel uncomfortable by the blowoff of non-conditioned air at the beginning of operation or the like in an air conditioner for a vehicle. CONSTITUTION:At the starting time of a blower motor 27, a current is applied to the coil 35 of a first relay 32 so as to close the normally opened contact 37a of the switch 37, thus rotating the blower motor 27 in the reverse direction. After the lapse of specified time, current application to the coil 35 of the first relay 32 is stopped to close the normally closed contact 37b of the switch 37, and a current is applied to a coil 36 of a second relay 33 so as to close the normally opened contact 38a of the switch 38, thus rotating the blower motor 27 in the normal direction. The fan of a blower is formed of a sirocco fan, but since the blast quantity of the sirocco fan at the time of reverse rotation is quite small, there is no fear of a large quantity of non-conditioned air being blown into the vehicle interior at true starting time.
