Title: Screw for multispindle extruding machine
Inventor: TANIMOTO ISAMU
IPC: B29C48/59
Filed: 1978-08-31
Abstract: PURPOSE:To prevent uneven kneading and also to improve extruding capacity by keeping a clearance between a thread side and another thread side of the screw for interlocking anisotropic rotary multispindle extruding machine nearly constant in any positions.

Title: Communication equipment and storage medium
Inventor: KATO ATSUNORI
IPC: B41J29/38
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To systematically execute the optimal reception restoring processing in a communication equipment connected by various use configuration in a network environment. SOLUTION: This MFD(multi function device) is provided with an interface connected with a personal computer having a facsimile communicating function or a printer function and a data transferring function through a network. A CPU of the MFD reads priority processing information for deciding which reception restoring processing should be operated in the priority order when the back-up preservation of received data can not be operated from an RAM (S1). The CPU selects a reception restoring processing program with the high priority order based on the read priority processing information (S2).  Afterwards, when the destination of transfer is capable of reception (S3: YES), the CPU executes the selected reception restoring processing program (S4), and when the destination of transfer is incapable of reception (S3: NO), the CPU selects the reception restoring processing program with the high priority order next to it.

Title: Information processor
Inventor: KANAYAMA HIDEYO
IPC: G06F9/22
Filed: 1979-08-22
Abstract: PURPOSE: To ensure a low-cost time control by setting the address which does not exist in the memory device to the program counter PC and then securing a coincidence between the output of the memory device and the specified instruction code when the designation is given by the address mentioned above.  
     CONSTITUTION: Having the output information of n bits each, both the PC31 and the stack register 32 can designate the 2 n  units of addresses. And these addresses are larger than the address N the ROM30 possesses. Now in case a device having a low working speed is driven, the PC31 is defined as the address in which no program memory exists by the subroutine call instruction and after execution of the output ON instruction. Thus the no-operation NOP instruction is delivered from the ROM30. The PC31 is counted successively to execute the NOP instruction. And when the counting of the PC31 reaches the maximum address, the instruction 37 is delivered to carry out a similar working to the subroutine return instruction 36. Thus the PC31 is restored to the address next to the address of the instruction 35 to execute the output OFF instruction. In such way, the time control is possible with no increment of the program memory nor application of the timer counter.

Title: Manufacture of nozzle assembly
Inventor: HAYASHI KAZUNOBU
IPC: B41J2/16
Filed: 1984-05-25
Abstract: PURPOSE:To enhance manufacture of ink particles by providing a vibrator coaxially in the external circumference of a cylindrical nozzle and adhering/curing the internal circumference of the vibrator and the external circumference of a nozzle with an adhesive at lower temperature than a temperature used for an assembly. CONSTITUTION:A nozzle 1, a vibrator 3 and an adhesive 5 are kept at low temperature which is low enough to treat them, i.e. 0-5 deg.C, and an adhesive is injected into their clearance. Then they are left alone until the adhesive is sufficiently cured at low temperature. If the temperature is restored to normal after curing, an internal stress (compression stress) generates as an adhesive having high coefficient of thermal expansion 5 expands to press the external surface of the nozzle 1 and the internal surface of the vibrator 3. This compression stress plays an important role in the transfer of vibration from the vibrator 3. The expansion force of the adhesive 5 does not allow generation of a clearance in the vibration transfer system. Furthermore, in a state where the compression stress has worked, vibration is transferred satisfactorily.

Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To provide a level conversion circuit which is capable of stably converting, level independently of an amplitude of an input signal and reducing current consumption. SOLUTION: In this circuit, an amplitude detection bias circuit BG receiving an input signal Vin sets a gate bias voltage applied to a P-channel transistor(TR) MA high and a gate bias voltage applied to an N-channel TR MB low, when the amplitude of the input signal is high. Conversely, the amplitude detection bias circuit BG receiving the input signal Vin sets a gate bias voltage applied to the P, channel transistor(TR) MA low and the gate bias voltage applied to the N-channel TR MB high, when the amplitude of the input signal is low, Thus, a through-current flowing to the P-channel TR MA and to the N-channel TR MB is decreased, and the latch circuit is driven stably, even if the amplitude of the input signal is small.

Filed: 1989-04-28
Abstract: PURPOSE:To eliminate the use for a Faraday rotator by forming branch paths so as to satisfy specific conditions and connecting optical fibers to a main path and the branch paths of small propagation constants. CONSTITUTION:The branch paths 4, 5 are formed in such a manner that the value (betai-betaj)/(thetaXgamma) determined by the constant gamma expressed by equation I and a branch angle theta (radian) attains >=2 where the refractive index of the core of waveguides is designated as n, the wavelength (nm) of the guided light as lambda, and the propagation constants of waveguides as betai, betaj (betai>betaj). The optical fibers 6, 9 are photoconnected to the main path 3 and the branch path 5 of the small propagation constant. Since the incident light signal to the main path 3 from the optical fiber 6 is, therefore, made incident to the branch path 4 of the large propagation constant and absorbed in this metallic films 7, 8, the signal is not emitted to the optical fiber 9. On the other hand, the incident light signal from the optical fiber 9 to the branch path 5 is guided to the main path 3 and is emitted to the optical fiber 6. Thus the need for the Faraday rotator is eliminated and the inexpensive and small-sized optical isolator is obtd.

CONSTITUTION:A floating movment restricting member 26 acting as means for fixing the end of a wire for restricting a floating movement of the wire 12 in its returning direction regulates a body 17 to disengage from the engagement part 22 by engaging the locking claw 29 in the slit 23, and in turn resiliently depressing an annular member 18 upwardly under a resilience of the horizontal part 31. As a result, the wire 12 is regulated to move upward freely by an engagement between the body 17 and the engaging part 22, further its free and downward movement is regulated by an abutment of the annular member 18 against the upper surface of the horozontal part 31. That is, when the wire 12 is to be returned, the wire 12 depresses the throttle valve 5 downward through the annular member 18 and the horizontal part 31. Thereby, the throttle valve 5 is positively returned downward.

Abstract: PURPOSE:To prevent the mincing change of vehicle speed so as to improve the body sensation of an occupant by dulling the adjustment of driving force performed by a driving force adjusting means in order to make vehicle speed coincide with the target travel speed, in the case of judging a fuel cut-off condition or a condition of high possibility of fuel cut-off. CONSTITUTION:An adjustment dulling means dulls the adjustment of driving force performed by a driving force adjusting means in the case of a fuel cut-off condition detecting means judging a fuel cut-off condition or a condition of high possibility of fuel cut-off at the time of constant speed travel control. That is, adjustment is changed into slower action than normal, an action stopped state until reaching certain deviation or more, or the like, so that fuel cut-off is not stopped immediately or started immediately. The change cycle of vehicle speed therefore becomes long so as to prevent the generation of an uncomfortable phenomenon to a body sensation such as the mincing change of vehicle speed on a down-slope road.
