Title: Recovery of valuable protein from protein solution
Inventor: WAKITA MASAHIRO
IPC: B01D61/14
Filed: 1991-03-22
Abstract: PURPOSE:To recover valuable proteins from a stock solution in high yield while suppressing the adhesion of the proteins to a filter by adjusting the pH of the protein-containing stock solution near the isoelectric point of the protein, and filtering the solution from one side of the ceramic filter to the other side under pressure difference. CONSTITUTION:A protein solution generated in the preparation process of food proteins, etc., is used as the stock solution to be treated. The pH of the stock solution is adjusted to the isoelectric point of the protein in the stock solution or thereabout and the solution is supplied to a stock solution tank 11 and circulated to the filtration device 13 with a circulation pump 12. The solution is allowed to flow along a surface of the filter membrane of the ceramic filter in the filtration device 13 and passed through the filter membrane from one face to the other face by the pressure difference between both faces. The valuable proteins in the protein solution are passed through the membrane by this process while suppressing the adhesion of proteins to the filter and separated from the foreign matters in purified state. The valuable proteins can be recovered from the protein solution in highyield.

Title: Automatic music playing recorder
Inventor: MUKONO HIROBUMI
IPC: G10H1/00
Filed: 1990-03-30
Abstract: PURPOSE:To properly quantize performance information even when a tempo is varied by quantizing sound generation time based on tempo information corresponding to the progress of music. CONSTITUTION:A player sets a console panel 4 in recording mode to specify a melody track(MEL1) as a recording track and starts performance by operating a keyboard 1, and then the operation information of the keyboard 1 is sent to a tone generator 5 to generate a musical sound. Then the player sets the panel 4 in playback and recording mode to specify the MEL1 as a playback track and a rhythm track(RH) as a recording track, and dipresses switches A and B while listening to the reproduced melody sound to instruct the generation of a beat on a staff or a beat not on a staff, thereby recording them on the RH. Then when the MEL1 is specified as a track to be quantized, a CPU 6 quantizes the note-ON time of each melody sound recorded on the MEL1, generate each melody sound at timing accurately synchronized with the measure staffs and beats, and reproduces the music at a faithful tempo even if the tempo of the music is varied.

Title: Variable gain amplifier
Inventor: OKA KOJI
IPC: H03G3/12
Filed: 1985-04-19
Abstract: PURPOSE:To to reduce the size of a transistor (TR) and to reduce the variance of a process and a gain error due to temperature variation by constituting an inverting amplifier which uses an operational amplifier so that the on resistance of an analog switch which switches an input resistance and feedback resistance is proportional to the resistance value of a changeover resistance. CONSTITUTION:For example, analog switches SW5-SW8 have on resistances Ros1, Ros2, Rof1, and Rof2, which are alpha times (0<alpha<1) as large a changeover resistances, i.e. input resistances Rs1 and Rs2 and feedback resistances Rf1 and Rf2. When the SW5 and SW7 are on, the gain of this inverting amplifier is -(Rf1+Rof1/Rs1+Rof1)=-(Rf1+alphaRf1/Rs1+alphaRs1)=-[Rf1(1+alpha)/Rs1(1 +alpha)]=-R$df1-X/Rs1 and the gain is not affected by the influence of the on resistances of the analog switches and determined by the ratio of the input resistances and feedback resistances. Consequently, the variance in on resistance due to the variance of the process and the gain error due to variation in on resistance with temperature are reduced.

Title: Switching system for doubled equipment system
Inventor: TAKANO MASATAKA
IPC: H04Q3/545
Filed: 1987-04-07
Abstract: PURPOSE:To detect the fault of act/stand-by information and to execute the switching of a system without malfunctions by monitoring the act/stand-by information on both sides of the entrance and the exit of a doubled speech path equipment. CONSTITUTION:Each of doubled central controllers(CP) 1 and 2 monitors the act/stand-by state by providing the act/stand-by system confounding parts 20-22 on the entrance side and the exit side of the doubled speech path equipment. If the fault occurs in any speech path equipment the switching of the system of the speech path equipment and/or the central controllers 1 and 2 is executed according to the indication of the central controllers 1 and 2. The central controller of a stand-by system executes the switching of the system after diagnosing that there is no fault with monitored act/stand-by information. Thus, the CP of a new act system can be prevented from connected to the speech path system which can not be used.

Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a paving material for water draining elastic pavement having high bonding force on a roadbed and excellent water draining property of water sank into the inside thereof when it rains. SOLUTION: A paving material 10 is a flat plate having a thickness of 20 to 50 mm and is hardened and formed by mixing urethane binder with rubber chip aggregate and compressing and molding them for heat treatment. A cut-in part 11 is provided orthogonally for the direction of advance of a vehicle on a surface side 10a of the paving material 10.

Title: Discharge lamp lighting device and lighting system
Inventor: OTAKE HIROKAZU
IPC: H05B41/24
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp lighting device prevented from becoming large, capable of sufficiently removing noise, and hardly causing a hazard. SOLUTION: An a.c. voltage of a commercial electric power e is full-wave rectified by a full-wave rectifier circuit 4, filtered by a capacitor C5, and converted by an inverter circuit 6 into a high frequency a.c. to light a fluorescent lamp FL at a high frequency. Since the inductor L2 is in a high impedance state in 500 kHz or lower range in which a human body easily feels a hazard, electric current hardly flows via an earth capacitor C7 and no hazard is caused even n a case where a person touches the fluorescent lamp FL when the fluorescent lamp FL is exchanged during lighting of the fluorescent lamp FL. In the range higher than 500 kHz including the operation frequency of the inverter circuit 6, the inductor L2 is in low impedance state, noise attributed to the inverter circuit 6 can sufficiently be removed by the earth capacitor C7.
