Title: Manufacture of calcium silicate sheet
Inventor: IDE TSUTOMU
IPC: C04B28/18
Filed: 1987-06-12
Abstract: PURPOSE:To enhance strength and incombustibility and improve productivity by a method wherein cationic coalescing agent and anionic or nonionic coalescing agent are added to aqueous slurry containing the secondary particles of calcium silicate crystal and fibrous substance by the specified amount of the agents based on the solid content in said slurry and, after that, the resultant slurry is hydroextracted in the form of a sheet, pressed and dried. CONSTITUTION:The secondary particle is manufactured by hydrothermally and synthetically reacting silicic acid and lime as stock with each other under pressure and heat while stirring in an autoclave. The secondary particle and fiber-containing aqueous slurry are prepared by adding fibrous substance to secondary particles. After being blended with coalescing agents, the slurry is hydroextracted in the form of a sheet. The loads of the coalescing agents with respect to the solid content in the slurry are about 0.05-1.0wt.% of cationic coalescing agent and about 0.05-1.0wt.% of anionic coalescing agent or nonionic coalescing agent and at the same time the total loads of both coalescing agents are set not to exceed about 1.5wt.%. The hydroextracted sheet is pressed and dried. Further, when the pressing and drying of the sheet are done simultaneously, the strength of the sheet is contrived to be enhanced.

Title: Gap switch
Inventor: KONAKAWA MASAYUKI
IPC: H01S3/097
Filed: 1987-06-13
Abstract: PURPOSE:To enable a highly repetitive operation by sealing hydrogen gas in an insulated vessel housing a pair of electrodes. CONSTITUTION:Hydrogen gas (g) is sealed in an insulated vessel 1 housing a pair of electrodes 3 and 4, using a pipe 6 for introducing hydrogen gas. The dielectric breakdown voltage of hydrogen gas (g) sealed in the vessel 1 is approx imately equal to that of N2 gas, but an ion diffusion coefficient is approximately five times as large as N2 gas. Consequently, the recombination of ions is liable to occur on the inner wall of the insulated vessel 1 and deionization takes place quickly. As a result, dielectric breakdown is not caused at a low voltage, even if a highly repetitive operation is made.

Saturation pressure of solution is calculated by a control device 36 in response to these data, a saturation temperature of the refrigerant at that time is also calculated. In the case that its value becomes less than 0 deg.C, a refrigerant spraying solenoid valve 19 is closed in such a way the cold water and the refrigerant may not be freezed, the refrigerant blowing solenoid valve 18 is opened, and the refrigerant is blown toward the solution. In addition, a cooling water pump 35 is stopped to cause a saturation temperature of the refrigerant to be finally increased and its freezing is prevented.

Title: Manufacture of hetero-junction bipolar transistor
Inventor: INADA MASAKI
IPC: H01L21/331
Filed: 1991-06-20
Abstract: PURPOSE:To prevent current effectively from leaking from an emitter to an external base by forming an external base layer which has a conduction band having a higher potential than that of the emitter and a first base. CONSTITUTION:In a part which will become a collector mask, an SiO2 mask 10 is so formed that its stripe is a [110] direction. With the SiO2 mask 10 used as a mask, a first base layer p<+> GaAs4b is wet-etched so that about 50Angstrom  of the base layer stays behind to form a mesa 30. Then, the substrate is heated in an ultra-high vacuum with As being cast to remove the p<+> GaAs4b and expose a clean surface of an n-Al0.3Ga1.7As3. By the molecular beam epitaxy 40 performed from above, a p-Al0.4Ga0.6As7 having a large band gap is formed. By this method, electrons are effectively prevented from being injected from an emitter to an external base and thereby a collector-top type hetero-junction bipolar transistor having a large correct amplification factor is fabricated effectively.

Abstract: PURPOSE: To elongate the active life of a hydrogenation catalyst by bringing a working fluid into contact with an ion exchange resin in the manufacture of hydrogen peroxide using quinones.  
     CONSTITUTION: A working fluid contg. quinones is hydrogenated in the presence of catalyst, the resulting hydroquinone compound is oxidized, and after extracting hydrogen peroxide the working fluid is brought into contact with an ion exchange resin to recycle the catalyst. As the resin an anion exchange resin may be used singly, yet the anion exchange resin is preferably combined with a cation exchange resin. It is desirable to use a strongly basic anion exchange resin as the anion exchange resin. The contact temp. is ≤ about 60°C, and the fluid is preferably fed into a tower packed with the resin. The amount of the fluid fed is about 0.8W 10vol% to 1vol% of the resin, and the contact time is about 7hr. Thus, the life of the hydrogenation catalyst can be elongated to considerably reduce the amount of the catalyst used.

Title: Wire cut electrical discharge machine
Inventor: OBARA HARUKI
IPC: B23H7/06
Filed: 1980-10-23
Abstract: PURPOSE:To machine the corner part of a work with precision on an apparatus on which the work and a wire electrode move relatively under a fixed machining voltage by a method wherein the corner of the work is prevented from dulling under the maintenance of fead speed just before the corner and machining voltage. CONSTITUTION:The average voltage in machining gaps is detected by a detector like an integrator INT or the like and in machining in a usual straight part periodical sampling is conducted holding circuit SH according to a sampling pulse (a). By the output of this circuit SH machining conditions such as the fead speed, electrical conditions, etc. are controlled to hold a fixed average machining voltage. When the electrode moves from the straight part to he corner part, the NC unit NC computes the corner angle directly before machining the corner part and when the angle is within a desired value, sampling is stopped by the hold circuit HLD to fix machining conditions just before the corner. Accordingly, signals of fixed level always are outputted and wire tension is increased by the brake power of a reel for the decrease of machining quantity at the corner part under the fixed machining conditions.

Abstract: PURPOSE:To avoid a shock upon finishing the fuel cut by a method wherein a deceleration of a vehicle is detected and the rotating speed of the engine upon finishing the fuel cut in case the deceleration is higher than a predetermined value is made lower than the same in case the deceleration thereof is below the predetermined value.

IPC: H04M11/00
Filed: 1986-06-25
Abstract: PURPOSE:To automatically set the frequency of a transmission carrier from a MODEM LSI by installing an incoming signal detecting device detecting a call signal transmitted from a public telephone line and a holding device initializing held contents. CONSTITUTION:When the call signal is transmitted from an exchange through the public telephone line 2, a light emitting diode 4c in a photocoupler 4a emits light through a resistance 4d for limiting a current and a capacitor 4e for cutting a DC current. A transistor, receiving said light, is turned on, and a gate current IG in an SCR, which is rectified by a resistance 4f and a capacitor 4g in an integration circuit. Since a held current IH flows until the DC circuit of the public telephone line 2 is released after the call signal is received in such a way, a HIGH level is inputted to the mode setting terminal of the MO DEM LSI 7. After the DC circuit is released, a transistor 3l is turned off. Accordingly the held current IH stops, and a LOW level is inputted to the mode setting terminal LSI 7.
