Abstract: A copier with a (RDH) (20), has a document stacking tray (21) into which a set of document sheets is loaded for recirculative precollation copying, and a separate (SADH) document inlet (22) provided for semiautomatic non-precollation copying, utilizing a document gate for selectably directing documents to this tray or to be ejected from the RDH. All document jobs to be copied may be preloaded, and left unattended, for automatic sequential loading and copying, in a common stack, face-­down, as a batched plurality of intermixed documents and document set jobs interleaved with job slip sheets, in a job loader (F) adjacent the RDH which sequentially top feeds the documents into the SADH document entrance. Documents selected by slip sheet indicia or otherwise to be precollation copied are automatically loaded into the RDH stacking tray one job batch at a time, or up to a preset document tray capacity, and then automatically recirculatively copied, and then automatically unloaded and ejected. RDH jobs with a number of documents exceeding the tray capacity are automatically divided, separately loaded, and separately recirculated, in sub-job sets of documents. Documents to be copied in a non-precollation copying mode are not loaded in the RDH tray and not recirculated, and automatically ejected. This reloading, selective copying, and ejecting is repeated in job batches until all preloaded documents have been copied.

Abstract: The modified polypropylene resin composition of the present invention comprises a blend of a resin composition composed of polypropylene type resin (C) selected from the group consisting of a modified polypropylene (A) obtained by graft copolymerizing an unsaturated carboxylic acid or a derivative thereof and an unsaturated aromatic monomer onto a polypropylene, and modified polypropylene (A)/polypropylene (B) composition, and
     a saturated polyester resin (D),   an epoxy group containing copolymer (E), and   a basic compound (F) optionally added as a reaction accelerator.   
     The modified polypropylene resin composition according to the present invention is not only good in molding processability but also markedly effective in that it can give molded products much superior in physical properties to those obtained from individual polymers constituting the thermoplastic resin composition. 
     The novel modified polypropylene resin composition provided by the present invention can easily be processed into a molded product, a film, a sheet or the like by a molding method usually used for molding thermoplastic resins, for example, injection molding, extrusion molding or the like, giving a product which has a very good balance among stiffness, heat resistance, impact resistance, scratch resistance, coating properties, oil resistance, chemical resistance, water resistance, etc., and is excellent in appearance uniforming and smoothness. It can be advantageously used for a purpose requiring especially high heat resistance and impact resistance, in particular, low-temperature impact resistance.

Abstract: In a gate-controlled bidirectional semiconductor switching device, when a positive gate trigger signal is applied to a gate terminal (G), a first auxiliary thyristor is turned on, which is made up of an n-type 7th layer (7), p-type 4th layer (4), n-type first layer (1) and p-type 8th layer (13). An on-current of the first auxiliary thyristor that is caused at this time, is fed as a gate current through a second wiring (12) to a first main thyristor made up of an n-type 5th layer (5), p-type second layer (2), n-type first layer (1) and p-type 8th layer (13). The first main thyristor is turned on by the gate current. When a negative gate trigger signal is applied to the gate terminal (G), a second auxiliary thyristor is turned on which is made up of an n-type 6th layer (6), p-type third layer (3), n-­type first layer (1) and p-type 8th layer (13). In this case, a rectifier (16) prevents an on-current of the second auxiliary thyristor from flowing from the second auxiliary thyristor to the gate terminal (G) through the 4th layer (4). As a result, the on-current is comple­tely fed as a gate current to the first main thyristor without any leakage. Accordingly, the invalid current components in the second auxiliary thyristor is reduced, and the first main thyristor is effectively turned on.

Abstract: The present invention involves a newly synthe­sized chromogenic thiol-indicating isobenzothia­zolone derivative having the structure:
      In this structure at least one of R¹ and R² is preferably nitro, arylazo, substituted arylazo, benzylideneamino or substituted benzylideneamino. When only one of R¹ and R² is so substituted, one of R¹ and R² may be hydrogen. The R³ substituent is preferably alkyl, carboxyalkyl, hydroxyalkyl, aminoalkyl, haloalkyl, aryl, carboxyaryl, hydroxyaryl, aminoaryl, heteroaryl, carboxyheteroaryl, hydroxyheteroaryl, aminoheteroaryl, hydroxy, alkoxy, or amino. 
     A central utility of the compounds of the present invention involves their use in the detec­tion of thiols. Thus, the present invention com­prises a process for measuring the presence or appearance of thiols, particularly in an aqueous system. This process comprises contacting said aqueous system with a chromogenic thiol-indicating   isobenzothiazolone derivative as described herein. Chromophoric changes due to thiol-mediated reduction of the isobenzothiazolone derivative then occur. Such changes can be in a solution or on an indicator surface in contact or having been in contact with the aqueous system. The chromophoric changes, due to a bathochromic shift in characteristic light absorption upon reduction of isobenzothiazolone derivative, are proportional to the amount or rate of appearance of thiols in the aqueous system.

Abstract: An electronic controller switch (90) is disclosed for authorizing use of controlled devices. The electronic controller switch includes memory (112) for storing a plurality of data strings unique to the particular controlled device with which the electronic controller switch is used. Each data string includes an access code, a validation data bit, and a user time data value. A user provides an input code to the controller via a standard infrared transmitter (134) and an infrared receiver (130) coupled to the controller. In response to the input code provided by the user, a microprocessor (106) searches the memory to determine whether any of the data strings includes a corresponding access code. If a corresponding access code is found and the validation data bit of its data string is not set, then the user has provided a valid input code and will be authorized to use the controlled device (102). If the validation data bit is set, which indicates that the input code provided by the user has been previously used, the user will not be authorized. When the microprocessor determines that a user is authorized, the microprocessor will provide the use time data value of the data string to a timer (116), thereby to control the time period for which the user is authorized. Different data strings are provided with time data values corresponding to different duration time periods.
