Title: Guide for moving printing head
Inventor: HAINRITSUHI DEIYURU
IPC: B41J19/20
Filed: 1977-04-20
Abstract: A guide for directing a printing head parallel to a printing direction in a printing device, the said printing head being displaceable along two parallel, round guide rods which are maintained at a fixed distance from each other by sheet-metal clamps which extend transversely of the longitudinal direction of the rods and which are provided with bearing apertures in which the guide rods are clamped. The guide offers a comparatively high resistance against bending, so that a constant distance is maintained between printing head and record carrier.

Title: Transformer connection type dc-dc converter
Inventor: NAKAMURA MANTARO
IPC: H02M3/28
Filed: 1995-03-03
Abstract: PURPOSE: To suppress switching loss, surge voltage and current, etc., by attaining zero voltage and zero current at the time of turn ON/OFF of a transistor. CONSTITUTION: Upon turning a switching element 3 OFF, a first resonance capacitor 8 is discharged and a second resonance capacitor 11 is charged gradually. Consequently, the voltage across the switching element increases gradually from OV. Upon turning the switching element 3 ON, the second resonance capacitor 11 is discharged while simultaneously resonance takes place between the first and second resonance capacitors 8, 11 and a resonance reactor 12 and a resonance current flows through the switching element 3. Current flowing through the switching element 3 is thereby increased sinusoidally from O. With such arrangement, switching loss and surge voltage and current can be suppressed upon turn ON/OFF of the switching element 3.

Inventor: SHIOZAKI MASAYA
IPC: G03G9/087
Filed: 1988-02-26
Abstract: PURPOSE:To obtain a toner uniform is size distribution in good yield by incorporating a copolymer having water-soluble monomer units each with a specified polar group in a polymerizable composition and suspension polymerizing said composition in a dispersion medium composed of an inorganic salt difficultly soluble in water. CONSTITUTION:The fine inorganic salt powder difficulty soluble in water is once dissolved in an aqueous phase containing said powder by adding acid or alkali, and further precipitated into extremely fine particles by adding alkali or acid, and this aqueous phase is used as the dispersing medium. The copolymer has as the structural units the water-soluble monomer units each having -SO3X, X being H, Na, K, or Ca, and is added into the polymerizable composition, and this is suspension polymerized, thus permitting production of the fine oil droplets to be effectively prevented and the oil droplets to be stabilized by the presence of the again precipitated very fine inorganic particles.

CONSTITUTION:Inner liquid cooled small chambers 107 and outer liquid cooled small chambers 108 are formed in the inside of a piston 100 by inner ribs 104, outer ribs 105 and round ribs 106. The liquid cooled small chambers 107, 108 are formed in such a manner that a line S passing through the center 203 of an inscribed circle 202 is not aligned to a radial line 201 passing through the axial center 200 of the piston but placed not radially with a suitable slope alpha in the sectional shape crossing at a right angle with the axial line of the piston. Accordingly, rigidity unbalance in the radial and circumferential directions of the  piston can be decreased while rigidity as a whole can be improved, and area of  cooling surfaces can be increased to perform stable feed and discharge of cooling liquid for the liquid cooled small chamber.

Title: Data communication system
Inventor: HIGUMA MASAYUKI
IPC: H04L12/28
Filed: 1989-02-28
Abstract: PURPOSE:To perform highly accurate time synchronization by a method wherein when time is set from a main station data communication device to other follower station data communication devices, time required until response is returned from each follower station is counted and stored so that it is transmitted as a time setting command after set time compensation. CONSTITUTION:Since response time is unknown when transmission delay time is detected for the first time, a response time memory unit 15 is initialized. Therefore time setting is done as for a follower station 20 without any compensation with a time compensation operating device 13. Then time required until response is made from the follower station 20 is counted and stored as transmission delay time in a response time memory device 15. On the other hand for and after the second synchronization of time, compensation is performed with the value stored in the response time memory device 15 as a compensation value by the time compensation operating device 13, and it is returned to a main station 10 as a time setting command. This allows accuracy of time synchronization to be within an allowable limitation.

Title: Error correcting device for memory
Inventor: ONO KUNIO
IPC: G06F12/16
Filed: 1988-02-27
Abstract: PURPOSE:To accurately recognize the number of times of occurrence of soft errors to accurately decide maintenance, operation, and trouble analysis. CONSTITUTION:Address information sent from a central processing unit CPU is held in an address register 1 to read out stored data in a memory 2. The result is held in a register 3 and is inputted to an error detecting circuit 4. When one-bit error is detected by the error detecting circuit 4, a correction signal is sent to a correcting circuit 5 to correct one-bit error. Corrected data is sent to the CPU after being held in a register 6. When a one-bit error occurs, not only the correction signal but also an error syndrome error signal is generated. This error signal is sent to a diagnosing processor and becomes a trigger signal for gathering error information.

IPC: B60Q1/02
Filed: 1987-02-27
Abstract: PURPOSE:To prevent the operation of a turning on/off device from becoming unstable by shutting off an automatic lighting means from the power source so as to inhibit the automatic lighting of the illumination until an engine starts rotation and a generator generates more output than the specified value. CONSTITUTION:When an engine is started after putting an illumination turning on/off device E in an automatic control condition by a lighting switch 40, an alternator 10 is driven. Since the revolution number of an engine is below the specified value at the start, a regulator 20 makes each transistor Tr21, 22 nonconductive and Tr conductive under the action of a control circuit 24. In this condition, a power source circuit 90 is maintained in a reset condition and restarted without bringing about the automatic lighting of a front illumination 50 by the turning on/off device E. Thereafter when the revolution number of the engine becomes above the specified value the regulator 20 makes Tr21, 22 conductive and Tr23 nonconductive and with the operation of the power source circuit 90, fixed voltage is generated and the turning on/off device E is put in a condition capable of operating.

Title: Fine positioning device
Inventor: HATAMURA YOTARO
IPC: B23Q5/22
Filed: 1985-03-11
Abstract: PURPOSE:To make it possible to yield fine displacement with high accuracy in a manufacturing device or the like for a semiconductor by composing a fine positioning device of at least either of a displacement mechanism for a symmetrical parallel flexible beam and that for a symmetrical radial flexible beam. CONSTITUTION:When voltage applied to piezoelectric actuators 19a, 19b generates force f being of the same strength in Z axial direction, displacement yielded on displacement mechanisms 22a, 22b for a parallel flexible beam causes a strong press on a rigid body 15c, and the parallel flexible beams 16a, 16a, 16b, 16b are therefore bent to yield the displacement epsilon. This stretch strain is detected by a strain gauge 21, and the applied voltage controlled on the above detected value makes positioning to the target displacement possible. In addition, when the voltage is applied to the piezoelectric actuators 29a, 29b by means of displacement mechanisms 32a, 32b for radial flexible beam, rotary displacement can be similarly yielded. Thus the fine displacement and fine rotary displacement can be yielded with excellent accuracy.
