Title: Biosynthesis of hyaluronic acid
Inventor: DEBITSUDO EI SUUAN
IPC: C12P19/26
Filed: 1990-04-19
Abstract: PURPOSE: To create hyaluronic acid in more improved overall yield than given ratio of a nutrient by inoculating a hyaluronidase-negative microorganism into a fluid nutrient medium and culturing the microorganism under specific conditions.  
     CONSTITUTION: A liquid nutrient medium is fed to a sealed fermentation chamber 12 and a strain of hyaluronidase-negative microorganism producing hyaluronic acid is fed thereto and the inoculated microorganism is cultured under aerobic conditions to a point of exponential growth wherein the biomass of the microorganism has increased by a factor of 2 to about 10 times, based on dry weight of cells. Then, the microorganism is cultured under aerobic conditions of reduced dissolved oxygen availability by a method reducing dissolved oxygen content of the medium. A disproportionately larger amount of hyaluronic acid is produced during the exponential growth than it would have in the absence of the reduced oxygen availability condition.

Abstract: PURPOSE:To avoid defective recording/reproduction owing to abnormal diffraction by forming a chamber of a prescribed size at a corner of an outer peripheral edge part of a face of a transparent substrate covered with a hardened film which contains no information medium layer. CONSTITUTION:An information track 4 and an information medium layer 2 capable of recording/reproduction are formed at one side of a discoid transparent substrare 1. Then a chamfer having an angle alpha of 30 deg. and width (a) of 0.5mm. to the substrate 1 is formed at a corner of the outer peripheral end part of a face having no information medium layer 2. Then a hardened film having the thickness (t) of 15mum is formed on both sides of the substrate 1.

Title: Initial position setting method for type body in serial printer
Inventor: KUROKAWA SHIYOUWA
IPC: H02P8/32
Filed: 1982-06-16
Abstract: PURPOSE:To enable to obtain a wide allowable range for a fitting position of a position sensor, by a method wherein an initial position of a type body is set by rotating a stepping motor by 0-several steps until a predetermined stop excitational phase is reached after an output is generated from a position sensor. CONSTITUTION:The stepping motor 1 is rotated by a predetermined number of steps by a signal from the sensor 3, and the difference between the current excitational phase and a preset stop excitational phase for a position at which the motor 1 is to be stopped is calculated. The stop excitational phase is so set that a straight line 8 connecting the center of a base 5 and that of a positioning projection 6 becomes parallel with a platen 7. When the motor 1 is rotated by 0- several steps in accordance with the calculated difference and is stopped at the stop excitational phase, the initial position of the type body 4 can be set. Accordingly, a correct initial position can be set even when the fitting position of the position sensor is deviated from the correct position, and the allowable range for the fitting position can be widened.

As a result, if the capillary tube forces of a circumferential group 12 of slits 10 and the steam passage 20 are the same as that of the prior art, a supplying capability of the working medium liquid ie substantially increased. In addition, a heat absorbing surface and a heat radiating surface are composed of a plurality of cylinder members over an entire circumference of each of the evaporation part 17 and a condensing part 18, resulting in that the heat absorbing area and the heat radiating area are remarkably increased. Thus, it is possible to reduce an amount of heat absorption and an amount of heat radiation per unit area. As a result, it is possible to prevent a dry-out at the evaporation part 17 and at the same time a heat transferring capability of the heat pipe can be remarkably increased.

Filed: 1981-06-30
Abstract: PURPOSE:To complete patterning by the conventional wet and dry etching methods without providing any adverse effects on an Al wiring by a method wherein the Al wiring layer is provided with two layered protective films of Si3N4 and PSG prior to the patterning process. CONSTITUTION:An approximately 10<3>Angstrom  thick Si3N4 film 7 and then an approximately 4mum thick PSG film 6 are deposited by the CVD method on an Al wiring layer 3 located on an Si substrate 1. A resist mask 8 is applied and then the PSG film 6 is attacked by an HF+NH4F etchant at an etching rate of 10<2>Angstrom /sec. The etchant may attack the exposed Si3N4 film 7 after etching away the PSG film but the film 7 is little affected in the process and therefore no ill effect is expected. After rinsing and drying, the Si3N4 film 7 is subjected to plasma etching in a 5% O2+CF4 atmosphere under 250W, 1toll conditions for the formation of an opening. Application of O2 plasma follows whereby the resist 8 is turned into ashes and is removed. Patterning can be completed without any adverse effect on the Al wiring thereby enhancing semiconductor device reliability.
