Title: Controller for process gas chromatograph
Inventor: SASABE TAKAAKI
IPC: G01N30/86
Filed: 1979-06-29
Abstract: PURPOSE: To permit the control procedure for a process gas chromatograph at automatic running to be readily prepared by writing the operation command at manual running converted into a parameter in a sequence table, and reading out the table during manual running to output a control signal.  
     CONSTITUTION: At manual running, a manual operation command 16 is given to a manual controller 17, and also input to an encoder 27, in which the command is converted into a control procedure parameter, and the converted code similar to the input of an automatic running controller 21 is written in a sequence table 19. Even at manual running, similarly at automatic running, the control procedure in the table 19 is read out, decoded in the controller, and output from an output device 18 in order to control sampling units or analyzing units. At this time, manually giving an operation command has priority to the control signals from the table 19. Moreover, this permits the table 19 to be rewritten, and even at automatic running after that the table 19 is read out to analyze automatically.

Title: Molded polymer product with wettable surface formed from latently hydrophilic monomer and production process therefor
Inventor: JIYON BII ENSU
IPC: G02C7/04
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To obtain a molded polymer product which has a wettable surface having a good oxygen permeability without detriment to the mechanical strengths of the product by coating it with a latently hydrophilic polymerizable material.  
     SOLUTION: This molded polymer product (a contact lens) is produced from a polymer such as cross-linked polydimethylsiloxane. When applied to the surface of a mold, the latently hydrophilic monomer used for coating the product can easily form a uniform thin film on the surface in spite of the fact that the surface is relatively hydrophobic since the mold is usually made of a hydrophobic polymer such as polystyrene. An example of the monomer is 3- aminopropylmethacrylamide-N,N-diacetic acid diethyl ether (F-85) shown by the figure. When this compd., after polymn., is immersed in a neutral or weakly acidic soln., the amino groups change into hydrophilic ionic ammonium salt groups and the ethyl ether groups change by hydrolysis into hydrophilic ionic carboxylate groups.

Abstract: PURPOSE:To simplify the constitution of the title ice crusher, and to control the shake of the same caused by the crushing of ice blocks by providing a crushing body having a crushing projection disposed on the upper surface of the crushing body, which is opposed to the lower end opening of an ice block shooting cylinder, and by forming the ice block shooting cylinder so as to have its diameter made gradually larger from the lower end opening of said cylinder toward the upper end opening thereof. CONSTITUTION:A crushing body 24 made of a synthetic resin such as polyacetal has a disc part 24b provided unitarily therewith on the upper end of an engaging cylindrical part 24a which engages detachably with a connecting member 23 and, on the upper surface of the disc part 24b, at least one crushing projection 25 is protuberantly provided unitarily with the disc part 24b. The upper end opening of an ice block shooting cylinder 21 is covered with a cover 22 made of a transparent synthetic resin. Since the ice block shooting cylinder 21 is so made that its diameter gradually increase from the lower end opening of said cylinder 21 toward the upper end opening thereof, the uppermost ice blocks among a group of the ice blocks are easily turned sideways when a large quantity of the ice blocks fed into the ice block shooting cylinder 21 receives an upward force by the crushing action. Accordingly, the rate of crushing energy transmitted to the lower part of the ice block shooting cylinder 21 via the ice blocks to be crushed can be minimized.

Title: Sheet matching device of copying machine
Inventor: OZAWA TOSHIMIZU
IPC: B65H9/00
Filed: 1984-04-27
Abstract: PURPOSE:To improve durability of a device and to stabilize matching operation for a sheet by skewing a sheet by means of transport belts wrapped round taper rolls. CONSTITUTION:Taper rolls are disposed in the opposite tapering directions on a driving shaft 2 and a driven shaft 3 which are orthogonal to the direction of transporting a sheet. Transport belts 5 are stretched between the taper rolls 4, 4, thereby to skew a sheet. In this arrangement, power can be transmitted to the driving shaft without a conventional universal coupling. Therefore, as there is no abrasion of the universal coupling, durability can be improved, and as the transport speed will not fluctuate, stable matching operation for a sheet can be accomplished. The occupied area may be smaller as compared with the conventional device having inclined driving shaft and driven shaft to reduce the required space.

Title: Field effect semiconductor type chemical sensor
Inventor: HIRAISHI HISATO
IPC: G01N27/414
Filed: 1983-05-13
Abstract: PURPOSE:To reduce wiring resistance without impairing insulation between an FET sensor and a solution to be detected, by using metal silicide wirings. CONSTITUTION:The source region and the drain region and the source electrode and the drain electrode of a transistor are connected by metal silicide wires 31, respectively. Thus, the wiring is performed by using the metal silicide 31 comprising molybdenum and silicon or tungsten and silicon. A silicon oxide layer 32, which is formed by oxidizing the silicide, forms an insulating layer. Usually, the resistivity value of the metal silicide is larger than that of the simple substance of metal by an order of magnitude. When impurities are diffused in the silicon, however, the resistivity value is as small as 10<-1>-10<-2>, and the value of the wiring resistance can be made to be several tens - several hundred OMEGA. Since the insulating layer can be readily formed by the oxidiation of the metal silicide, approximately the same manufacturing processes as those in the conventional method can be used.

Title: Reverse current blocking device through grounding
Inventor: KOBAYASHI TAKESHI
IPC: H02H11/00
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To block a reverse current from ground to the common grounding terminal of an apparatus or equipment and to prevent the failure of or damage to the apparatus or equipment caused by the reverse current. SOLUTION: A voltage detecting part 10 detects a forward voltage generated between a common grounding terminal and a grounding. When the detected voltage satisfies a voltage set by an operating voltage setting part 20 and exceeds an internal reference voltage, a control voltage is given from a control voltage generating part 30 to the Gate G of an SCR 4a in a switching part 40 to turn on the SCR 4a. This makes a current flow from the common grounding terminal to the grounding to protect an apparatus.  If a current caused by a thunderbolt, etc., flows on the ground and a reverse voltage is applied between the common grounding terminal and the grounding, the control voltage is not applied to the Gate G of the SCR 4a and by making use of the phenomenon that a reverse voltage is applied between the anode A and cathode K, the SCR 4a is turned off to isolate the common grounding terminal and the grounding for the prevention of the phenomenon of the reverse current.
