Title: Switching control system
Inventor: MORI HIROMI
IPC: H03M7/38
Filed: 1985-07-25
Abstract: PURPOSE:To prevent mis-matching for the changeover to the coding system optimized to a MODEM at coder and decoder sides even if noise exists in a transmission line by detecting a phase change to detect a training signal in the adaptive differential coding system and using the detection signal for changeover. CONSTITUTION:When the training signal of patterns A, B is inputted to a signal detection circuit 18, a positive value is consecutive in the output of a zero cross identifier 19 as shown in figure (a). A counter 20 increments the count by '1' or clears the count depending whether the output of the identifier 19 is positive or negative. A comparator 22, when the count exceeds a value '100' shown in the figure, retards the locking of the circuit 18 via a F/F 25 to detect surely the end of the patterns. When the count exceeds a value '300' shown in the figure, a comparator 21 brings the output of a F/F 24 to level 1. Thus, when the pattern is finished and the output of the identifier 19 is a negative, an AND circuit 27 outputs '1' level and an output of a F/F 26 allows a coder to switch a quantizer and a forecast device semi-fixedly and fixedly and allows a decoder to switch an inverse quantizer and a forecast device.

Title: High level production of cow growth hormone
Inventor: POORA MEIYAAZUUKIISU
IPC: C12N15/18
Filed: 1986-07-15
Abstract: A high density fermentation process for high yield production of a protein having bovine growth hormone activity by transformant E. coli strains is described. The process employs transformant strains of E. coli containing a gene coding for a protein having bovine growth hormone activity under the control of a bacteriophage lambda promoter-operator and a gene coding for the λc1857 temperature-sensitive repressor protein. In the initial growth period, the level of dissolved oxygen in the fermentation medium is maintained at about 20% to 60% saturation and the temperature of the medium is maitained at a temperature at which the λc1857 repressor protein is active. Production of the desired protein is then induced by raising the temperature of the medium to at least about 42°C. The temperature is then reduced to about 38°C to 41 °C to optimize cell growth for the remainder of the induction period, during which the level of dissolved oxygen in the medium is maintained at about 10% to 40% saturation, and the protein having bovine growth hormone activity thus produced is recovered from the transformant cells.

Title: Fringe scanning interferometer
Inventor: YAMADA TAKATOSHI
IPC: G01B11/24
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To lessen the influence of stray light to stably measure at a high accuracy by modulating the light source intensity of a fringe scanning interferometer with a specified frequency. SOLUTION: The light source intensity of a fringe scanning interferometer is modulated with a frequency f=(c/PD).n, the resultant intensity variation of the interference fringes is as shown by the equation (n is an integer, a is the depth of intensity modulation, OPD is the optical path difference between the measurement and reference optical paths, c is the light velocity, ϕ is the wave front aberration of the measured object, and ω is the angular frequency of the light source). Namely, when the intensity modulation is carried out, the intensity variation of the interference fringes is max. when n=f.(OPD/c) is an integer but it is low in other cases.  Accordingly if the optical path difference is set so that n is an integer, the intensity variation of the interference fringes is max. and the intensity variation of the interference fringes due to stray light is lower than it. In this way, it is possible to lessen the influence of the stray light.

The excretion residue obtained by the screen 2 is finely divided by a grinder 4 to be charged in an excretion residue pit 5 and guided to a flocculation tank 6. The excessive sludge generated in the biological treatment tank of a post-process is guided to the flocculation tank 6 from a sludge storage tank 7 and the finely divided excretion residue is stirred and mixed with the excessive sludge under the addition of a proper amount of a flocculant (a). At this time, the finely divided fibers contained in the excretion residue become a dehydration aid and strong flocs are formed around said fibers functioning as nuclei. Said flocs are guided to a dehydrator 8 to be dehydrated while a cake 8a is incinerated and a filtrate 8b is returned to the storage tank 3.

IPC: B60L15/00
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To reduce the loss in constant speed running and increase the running distance in a single charging. SOLUTION: In a double motor driven electric vehicle, torque instructions τ1 and τ2 which correspond to an acceleration signal As are sent from a vehicle controller VC to inverters INV 1 and 2, and the motors M1 and M2 of rear wheels W1 and W2 are driven by the inverters. The motors M1 and M2 are driven by setting the torque instructions at 0% and 100%, in response to the acceleration signal As , and alternately sending the instructions to the INV 1 and 2 during constant speed drive, by detecting the constant speed drive status. Although a torque of 100% is outputted as the motors M1 and M2 are alternately driven by a torque instruction of 100%, the motors M1 and M2 are not driven simultaneously. Therefore, the number of motors driven is 1, and motor iron loss and inverter loss are almost halved, compared with the case wherein two motors are simultaneously driven.
