Title: Production of aminoalkylsulfonates
Inventor: MATSUURA NOBUHIRO
IPC: C07C303/02
Filed: 1995-03-31
Abstract: PURPOSE: To enable the reduction in equipment cost due to facilitated control over reactional temperatures without requiring operations to regulate the reactional pH and produce the subject high-purity compounds in high yield by using an aziridine compound as a raw material and further an aqueous solution of a hydrogensulfite. CONSTITUTION: (A) An aziridine compound of formula I (R<1> and R<2> are each H or a 1-3C alkyl)is reacted with (B) an aqueous solution of a hydrogensulfite to provide (C) aminoalkylsulfonates of formula II. Furthermore, the resultant reactional product solution containing the prepared compounds of formula II and a sulfite is then preferably reacted with sulfurous acid gas to convert the sulfite into the hydrogensulfite and the components (C) and (B) are preferably separated from the reactional solution by crystallization and filtration. The separated component (B) is more preferably reutilized. The reaction can be carried out by dropping ethyleneimine to, e.g. an aqueous solution of sodium hydrogensulfite to provide aminoethanesulfonic acid.

Title: Microphone device
Inventor: BABA HIROYUKI
IPC: H04R3/00
Filed: 1984-04-17
Abstract: PURPOSE:To give an appropriate directivity appricable to the entire band including a low frequency range by constituting a line microphone of an acoustic tube and a microphone and fetching the output difference between an output of said micrphone and that of another microphone provided ahead of the former. CONSTITUTION:An output of a non-directly microphone 5 is appropriately level- adjusted and inpressed to one input terminal of a subtractor circuit 7. Since an output of a non-directivity microphone 4 is impressed to the other input terminal, the subtractor circuit 7 can fetch the output difference between both outputs of the microphone 5 and 4. Assuming that a length of an acoustic tube 1 and an interval between the non-directivity microphones 4 and 5 are l and d, respectively, a low frequency range which has been conventionally of non directivity becomes a single directivity in case of d l. It is recognized in case of d 2l that the low frequency range shows the directivity near to two-way directivity.

Title: Exhaust gas disposal method for semiconductor manufacturing equipment
Inventor: NAKANO ATSUSHI
IPC: H01L21/31
Filed: 1979-06-19
Abstract: PURPOSE:To enable the application of self-inflammable exhaust gas to decompression gas-phase growing equipment without reducing the concentration of the self- inflammable gas, by introducing O2 gas or O2-containing inert gas into the self- inflammable exhaust gas so that they react with each other and using a water pump to suck and discharge the gases. CONSTITUTION:SiH4 gas released from an SiH4 gas inlet pipe 1 by an exhaust unit 2 is conducted to a reaction tube 3. O2 gas or O2-containing inert gas is introduced into the reaction tube 3 by a blower 4. The SiH4 gas reacts with O2 in the reaction tube 3 so that the SiH4 gas burns and SiO2 and H2O are produced. The resulting products and gases are sucked by a water pump 5. The solid SiO2 is contained in water supplied by the pump 5 and is discharged together with the water through a drain port 6. The remaining O2 and inert gas are released through an exhaust port 7. According to this constitution, the SiH4 gas of 100% in concentration can be used for decompression gas-phase growing equipment without reducing the concentration of the gas. As a result, numerous semiconductor wafers can be treated.

Title: Reducing device of music level
Inventor: SHINOHARA MASAO
IPC: H03G3/20
Filed: 1980-06-10
Abstract: PURPOSE:To reduce selectively only the music level, by inserting an electron control variable attenuator into the signal route of a audible frequency amplifying system and varying the degree of attenuation of the atennuator with the control DC voltage that received a wave detection and integration. CONSTITUTION:An electron control variable attenuator 7 is inserted in the middle of an audible frequency amplifying system. The signal is divided in front of the attenuator 7, and the divided signals are made to pass through a voice band eliminating filter 1.

Filed: 1980-06-09
Abstract: PURPOSE:To enhance the endurance by interposing a diffusion layer whose As concn. is increased gradually toward an Se-base charge transferring layer between the transferring layer and a charge generating layer made essentially of Se-As alloy so as to prevent the generating layer from being cracked. CONSTITUTION:On a support 1 an Se-base charge transferring layer 2 is formed with Se doped with halogen, an Se-Te alloy or the like. By regulating the amounts of Se and As2Se, a diffusion layer 3 whose As concn. is increased gradually is vapor-deposited on the layer 2 while keeping the support temp. at <=80 deg.C not to crystallize the layer 2. After depositing the layer 3 in a prescribed thickness, a charge generating layer 4 of an Se-As alloy having 30-40wt% As concn. is formed. The layer 4 is coated with an insulating and protective layer 5 of polyester or other resin as required. The layer 4 is hardly crystallized and is not cracked. Thus, a receptor free from fatigue due to repetition and having superior sensitivity in a longer wavelength region, etc. is obtd.

Abstract: PURPOSE:To automate the mold opening/closing process by a method wherein the changing-over of fluid pressure is performed at optimum timing by means of a controlling device on the judgement of the coincidence of the change of the distance between a mold clamping housing and a movable mold detected with a sensor with a reference value. CONSTITUTION:Since a scale 10 is fixed to a mold clamping housing 1 and a position marker 11 is fixed to a movable mold 2, the distance between the mold clamping housing 1 and the movable mold 2, which changes through the extension of toggle links or the elongation of tie bars 6, is detected with an image sensor 12 in order to detect the distance through the conversion to electric signal. In order to control mold clamping on the basis of the electric signal sent from said distance detecting means, a circuit 20 to detect the generation of mold clamping force, a circuit 21 to detect the mold touching state and a controlling device 16 are provided. A valve changing-over device 18 changes over a fluid pressure changing-over valve 19 upon receipt of a control signal VC sent from the controlling device 16 so as to change over from low pressure fluid to high pressure fluid at the timing for generating mold clamping force in order to extend tie bars 6, resulting in generating the desired mold clamping force.

Title: Gas detector
Inventor: ASHIZAWA YUKIO
IPC: G01N27/12
Filed: 1979-06-20
Abstract: PURPOSE: To make it possible to generate an alarm securely when electric power feed is started in an atmospher where gas stays while making no response to a false signal generated in a certain time right after the electric power feed is started.  
     CONSTITUTION: On the start of electric power feed, gas detecting element 3 is heated by heater to generate false signal a' of a gentle wave regardless of whether gas resides. The signal is input to comparing circuit 9 via smoothing circuit 4 and then compared there to a reference voltage, determined by resistances 6 and 7 corresponding to the density of the gas, to obtain signal c'. Charge stopping circuit 15 prevents charging-discharging circuit 12 from being discharged by signal c' via discharging circuit 21 within the duration time of signal c' after the electric power feed. After signal c' disappears, alarm unit 24 sends out an alarm by the detection signal output by detecting element 3. When the electric power feed is started while the gas resides, the detection signal is a sustained wave differing from signal c', so that the alarm can be given. Therefore, the alarm can be sent out securely.

Abstract: PURPOSE:To prevent that a viewer misconceives for the voice broadcasting mode of TELETEXT by preventing the display of the changed voice broadcasting mode of television broadcasting at the same channel as that for the TELETEXT even when the voice broadcasting mode of the television broadcasting is changed while the viewer views the TELETEXT. CONSTITUTION:A CPU 36 for selecting stations changes one piece of processing to another piece of processing without detecting the voice broadcasting mode under a character mode. Consequently, the changed voice broadcasting mode of the television broadcasting at the same channel as that for the character broadcasting is never displayed on the surface of an image receiving tube 19 even when the voice broadcasting mode is changed under the character mode, and in the same manner, the display of an LED 42 for displaying a stereo mode is never changed. Thus, the viewer never misconceives for the voice broadcasting mode of the TELETEXT.
