Title: Dc-dc converter
Inventor: OYA MASAYOSHI
IPC: H02M3/335
Filed: 1988-07-29
Abstract: PURPOSE:To reduce loss by using the leakage inductance of a transformer for resonance. CONSTITUTION:A DC-DC converter is composed of a semiconductor switching element 1, a transformer 2, a rectifying diode 3, an output smoothing capacitor 5, an output smoothing choke 6, etc., and supplies load with DC voltage. A capacitor 7 for resonance is installed at that time, and the leakage inductance 8 of the transformer 8 is operated for resonance. Resonance currents by the capacitor 7 and the leakage inductance 8 flow, and prevented by the diode 3. Accordingly, a current gradient is made easy when the semiconductor switching element 1 is turned ON, and the semiconductor switching element 1 is turned OFF after currents finish flowing, thus eliminating the overlapping of voltage currents even at the time of turn-OFF.

Title: Instrument fixing construction in glove box
Inventor: SUZUKI KOICHI
IPC: B60R11/02
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To eliminate a specially constructed instrument panel for installing instruments in a glove box, compensate manufacturing error, and facilitate aligning of the instruments to a cover at the instrument panel side. SOLUTION: A CD changer 42 in a glove box 12 is fixed to a instrument panel reinforce 20 by both CD changer brackets 24 located right and left side and a reinforce bracket 36. Since a CD change cover 46 is large compared to a opening 62 of a lower panel 60, even if the CD change cover 46 generates some manufacturing errors with respect to the opening 62 of the lower panel 60, the errors can be compensated at the mating of the opening 62 of the lower panel 60 with the CD change cover 46.

Inventor: TODA MANABU
IPC: H04M1/64
Filed: 1990-07-18
Abstract: PURPOSE:To carry on automatic answering even when another telephone set is connected to a line while an automatic answering telephone set is in automatic answering mode by providing an automatic answering continuation requiring means and an automatic answering resetting inhibition means. CONSTITUTION:When a telephone set 16 other than the automatic answering telephone set 12 is connected to the line while the automatic answering telephone set 12 automatically answers to incoming from an opposite-side terminal by an automatic answering function part 13, automatic answering continuation request means 19 sends a signal for requesting the continuation of the automatic answering to the automatic answering telephone set 12. The automatic answering resetting inhibition means 15 inhibits an automatic answering resetting means 14 incorporated in the automatic answering telephone set 12 from performing resetting operation according to the continuation requiring signal from the automatic answering continuation requiring means 19. Consequently, the automatic telephone set 12 need not suspend the automatic answering and respective telephone sets can acquire lines.

Title: Electrostatic recording body
Inventor: MAEDA MITSURU
IPC: G03G5/14
Filed: 1986-08-18
Abstract: PURPOSE:To form an image high in image density, small in background stains, and superior in resolution in independence of circumstantial conditions by both the double and single side control systems by imparting electric conductivity to a substrate with a fibrous material composed essentially of tin oxide. CONSTITUTION:The electrostatic recording material is obtained by forming a recording layer composed essentially of an insulating resin on the conductive substrate, which is made conductive by dispersing the fibrous material composed essentially of tin oxide in the substrate, thus permitting the electrostatic recording body to be made an all-weather type. It is embodied by mixing the fibrous material composed essentially of SnO2 into paper pulp at the time of paper making for the substrate, and thus lowering the volume resistivity of the substrate. A conductive layer is formed on one side or both side of the substrate thus obtained, when needed, and the recording layer composed essentially of the insulating resin and a pigment is formed on one side of it.

Title: Deburring method after pressure-welding between end faces of round bar shaped work
Inventor: OUCHIYAMA TAKASHI
IPC: B23K20/12
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To eliminate fracture in deburring by friction-welding a round bar shaped work, inserting the friction-welded work in a deburring device, making the work stand by for a prescribed time, and deburring the joined part. SOLUTION: A friction-welded material 3 is inserted in a punch die 13. A pair of photo-sensors 15a, b, sensing the insertion of the material 3, actuate a timer 16. With a prescribed time passing, the timer 16 transmits a signal to a control device. An elevation means is actuated, a punch 14 lowered, and the burrs 4 of the material 3 die-cut. The material 3 after the friction welding is made to stand by for a prescribed time in the punch die 13, with the burrs 4 die-cut in a state where the temperature is low in the joined part 3a of the material 3. As a result, no fractures develop in the joined part 3a. Cooling time is taken in a deburring device; therefore, no influence is imparted to the cycle time of the friction welding device, and no productivity is lowered. Consequently, very few defective products are produced.

Title: Sample hold circuit
Inventor: SONE KAZUYA
IPC: G11C27/02
Filed: 1990-07-19
Abstract: PURPOSE:To improve a hold characteristic by combining the first - third differential circuits and a constant current source, and connecting a held capacity and the base of an emitter follower circuit with the junction between the corrector of the third differential circuit and the emitter of the first transistor. CONSTITUTION:The transisters(Tr) Q14 and Q17 of the second and the third differential circuits are turned to ON, the Tr Q15 and Q16 of them are turned to OFF, at the time of a sample mode. When the base inputting signal Vin of the first differential circuit is larger than a signal V0, the difference between a constant current source I14 and the current of a Tr Q12 runs to the base of a Tr Q13. The Tr Q13 charges a hold capacity(C)H, the base of a Q18 is con nected with the CH so that the emitter follower operation can be attained, and a signal V0 is taken away from the emitter. The potential of the CH rises accord ing as it is charged, and the signal V0 rises and follows a signal Vin. The Tr Q13 is turned to OFF due to the conduction of a diode at the time of a hold mode, the charging operation is stopped, and the instantaneous value of the potential of the CH is held. Thus, the hold characteristic can be improved.

Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To prevent the production of an error due to the mismatching of correspondence between a transfer file format and the definition of a relational data base management system(RDBMS) table and the production of a program description error in a specific part of SQL language (4th generation langage) in generating a data transfer program to a relational data base through a file.
