IPC: H02K53/00
Filed: 1981-04-24
Abstract: PURPOSE:To generate a current by synchronously detecting a given current with sinusoidal and cosine waves and adding the obtained detected outputs. CONSTITUTION:A current I0sin(omega0t-pi/4) is inputted to an input terminal, and is synchronously detected with sinomega0t, cosomega0t. Thus, output currents I0cospi/4, I0sinpi/4 can be respectively produced by this detection. These output currents  are added, thereby obtaining an output current 2<1/2>I0.

Title: Image recorder
Inventor: YODA YASUNOBU
IPC: G03G15/20
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To prevent even thin paper low in friction from sliding over a roller in a fixing unit, to suppress fluctuation of carrying speed and, to ensure a fixing rate. SOLUTION: The rotation of a main motor 33 is transmitted to an opposed- roller-shaft drive gear 37 via a transmitting system, thereby rotating and driving an opposed roller 26 and causing the fixing roller 25 to follow the rotation of the opposed roller 26. Thus, since a carrying force is exerted to the paper from the opposed roller 26 higher in surface friction force than that of the fixing roller 25, the paper can be passed through the fixing unit at the stable carrying speed.

Title: Rotary head type recorder
Inventor: EDAKUBO HIROO
IPC: G11B5/027
Filed: 1983-04-11
Abstract: PURPOSE:To avoid an evil effect due to the signal recorded previously for the reproduced signal of the area where the recording is newly performed without having a complicated structure nor a complicated circuit constitution, by using either one of two types of heads. CONSTITUTION:A switch 24 is connected to an R side terminal when a tape 5 reaches the insertion record start timing. Thus the signals sent from input terminals 23V and 23A and the signal given from a pilot signal generating circuit 27 are turned into the signal forms which are suited to recording. These signals are amplified by a recording amplifier 26 and then supplied to recording ''Sendust'' heads 2R and 2L. Thus signals are newly recorded. A ferrite head 3R is shifted by 1/2 track pitch (P/2) toward a track 37 on a tape pattern to the head 2L. Then a changeover switch 7 is connected to an E side terminal when the head 3R reaches a point on the tape 5 where the insertion record is started. Thus it is possible to erase precedingy the track where the recording is carried out by the head 2L.

Title: Transporting method for chlorobutadiene latex
Inventor: IKURA YOSHIHARU
IPC: B32B25/12
Filed: 1994-03-31
Abstract: PURPOSE:To make stable transport possible for chlorobutadiene latex with adhesion of the polymer to the inside of a hose decreased by a method wherein a rubber hose made of ethylene-propylene rubber provided to a part to which chlorobutadiene latex makes contact is used for transport. CONSTITUTION:For transporting chlorobutadiene latex with a rubber hose, a rubber hose with ethylene-propylene rubber provided to a part to which chlorobutadiene latex makes contact is used. The rubber hose is made up with its innermost layer made of ethylene-propylene rubber while the outer layer thereof being made of a natural rubber. However, an optimum material is desirable to be used for the outer layer in accordance with circumstances, in which the rubber hose is used. In the case where the rubber hose is used repetitiously as a tube for a tube pump under circumstances where deformation is likely to occur, natural rubber is desirable to be used for parts other than the innermost layer in view of shape-keeping ability of the rubber hose. Thereby, adhesion can be decreased extremely, and the latex can be transported stably for a long period of time.

Title: Memory access system
Inventor: DAIMON TOSHIYUKI
IPC: G06F9/06
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To facilitate on-board programming of a flash memory by providing an address decoder for translating the output address of a CPU to the mapping address of a boot mode. SOLUTION: An address decoder 4 receives a boot mode signal at the time of the boot mode, generates the enable signal of a boot memory 3, translates an address from a CPU 1 to the mapping address and respectively outputs the enable signal to the boot memory 3. Thus, since the address decoder 4 translates the mapping address of the boot memory 3, even when a microcontroller is activated in the boot mode, the mapping address of a flash memory 2 can be activated while keeping the same arrangement as a user mode. Therefore, in the case of on-board programming, the address of an instruction to be arranged in the flash memory 2 can be programmed and prepared by writing/erasing the flash memory 2 without caring of the boot mode.

Title: Electronic still camera
Inventor: KITAJIMA TATSUTOSHI
IPC: H04N5/781
Filed: 1991-03-05
Abstract: PURPOSE:To suppress power consumption for storage and transfer by not storing screen information obtained without being flashed when an object is in the environment of flash photographing and a camera system is in the state of the flash photographing. CONSTITUTION:When a system control part 15 recognizes that the object is in the environment requiring flash light emission by photometric information that a fluctuation level drops below a flash critial level from a photometry circuit 19, the control part 15 sends out a storage prohibition signal through a flash driving part 115 to a storage prohibition part 117. The storage prohibition part 117 prohibits the transfer of picture data for each frame sent out to a memory driving part 112 to an internal memory 113. In such a manner, by performing control so as not to let the picture data by consecutive photographing image picked up without performing the flash photographing transferred to the internal memory 113 in a time area requiring the flash photographing, the need of power for writing and reading the unnecessary picture data is eliminated.

Abstract: PURPOSE:To attain supervision/control with excellent response and high reliability by providing a data identification section, a data demultiplex section and a data multiplex section to a drop/insert station. CONSTITUTION:A data identification section 2 of a drop/insert station D/I 1 identifies a data for monitor control sent from a host station and informs whether or not a data is a data of its own station to a data demultiplex section 3 and the sent data is stored tentatively in a memory 4. Upon the receipt of a notice of its own station data, the demultiplex section 3 demultiplexes its own station data and fetches it and when the data is not its own station data, the data in a memory 4 is sent to a subsequent station via a data multiplex section 5. If a data sent from its own station exists, the data in the memory 4 and the data sent from its own station are multiplexed and the result is sent to the subsequent station Since the data does not pass an undesired circuit, the supervision/control with excellent response an high reliability is attained.
