Patent JP-S62200923-A (JP)
Title: Power supply synchronization direct spread modulator/ demodulator
Inventor: OOTA KAZUO
IPC: H04J13/00
Filed: 1986-02-28
Abstract: PURPOSE:To obtain an inexpensive modulator/demodulator with a simple consti tution precluding the possibility of loss of synchronization by allowing a reset means to reset a PN coder and a frequency divider at a period being an integral number of multiple of the AC power supply period. CONSTITUTION:A zero cross detection circuit 16 and an edge detection circuit 17 constitute a reset means. A noise component and a high frequency signal component are eliminated from an AC power supply of a low voltage distribu tion line 3 by a noise filter 16 to form the sinusoidal wave of a power frequency. The sinusoidal wave is formed into a rectangle wave (b) using the zero cross of the sinusoidal wave as a change point by the zero cross detection circuit 16. The edge detection circuit 17 detects the change point to generate a reset pulse having a narrow pulse width at every change point. Since PN code genera tion shift registeres 8, 2 and a frequency divider 19 are reset periodically, the PN code series at the modulation circuit side and the PN code series at the demodulation circuit are synchronized always with the power period fixedly.

Title: Intake valve for internal combustion engine
Inventor: OTSUBO JO
IPC: F01L3/02
Filed: 1993-02-09
Abstract: PURPOSE:To reduce an amount of deposition material adhering to the back side of a shade of a valve body. CONSTITUTION:A coating layer 13 having oxidation catalyst function is formed on an outer peripheral surface on a position located inside an intake port of a valve body 1. Thus, even when organic material having a high boiling point oozed out from mixture gas or a gap between a valve guide 3 and the valve body 1 is adhered to that position, the material is immediately separated from the surface and diffused because of oxidation catalytic reaction caused by an operation temperature of the valve body 1. It is thus possible to prevent the organic material having high boiling point from being carbonized and deposited around the back side of a shade 12.

Title: Outdoor molded transformer
Inventor: TOKIMITSU FUJIO
IPC: H01F27/32
Filed: 1994-03-15
Abstract: PURPOSE:To make a case lightweight by a method wherein the content of a molded transformer which is composed of a core and of a winding is housed in the case and the case is made of a synthetic resin. CONSTITUTION:A content 20 which is composed of a core 2 and of a winding 3 is housed in a case 1A made of a synthetic resin, and a molding resin 5 as a mixture of granular silica sand 51 and an epoxy resin 52 is filled. Then, in a completed state, the epoxy resin 52 is hardened, and the core 2, the winding 3 and the synthetic-resin case 1A including the silica sand 51 are integrated. Thereby, since the coefficient of thermal expansion of the synthetic resin is large as compared with that of a steel plate, the housed content in the case is expanded due to a temperature rise, also the synthetic-resin case 1A is expanded thermally, and a stress is not increased so much. As a result, the thickness size of the case is made similar to that of the steel plate, and the case can be made lightweight.

IPC: H02J7/10
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To smoothly switch the charging current of a battery charger having a charging current switch function with a simple circuit configuration. SOLUTION: A circuit for controlling switch of charging current is provided with a transistor Q1 to the base and collector of which the detected input of a charging output voltage V0 and the voltage V0 are respectively given and the emitter of which is connected to the mid point between output voltage V0 divider resistors R1 and R2 and the circuit outputs an output current control voltage VB by amplifying the control voltage VA at the mid point between the resistors R1 and R2. When the output voltage V0 is low, the transistor Q1 is turned off and the circuit outputs a first control voltage value and, when the output voltage V0 increases, the transistor Q1 is turned on before and after a specific output voltage value and the circuit shifts to a second control voltage value from the first control voltage value through an gradually changing intermediate voltage value.  Then a power source section 1 first outputs a charging current of a first current value and, as the output voltage V0 increases, another charging current of a second current value gradually through an intermediate current value.

Title: Illumination of inside of refrigerating showcase
Inventor: UEKUSA YUTAKA
IPC: F25D11/00
Filed: 1989-02-23
Abstract: PURPOSE:To improve the lighting performance of illuminating lamps and reduce the possibility of spoiling the life of an illuminating device by a constitution wherein illumination in a case is extinguished simultaneously with the closing of a shop while the same is lighted either upon finishing or starting of defrosting while the shop is closed. CONSTITUTION:Upon entering into defrosting operation, a timer contact 21a is closed instantaneously to release the exciting of relays 20, 24 and open the other contacts 20a, 24a while the exciting of a relay 17 is also released to open a contact 17a and stop a compressor 16. On the other hand, a contact 20b is closed to conduct a heater 26. Thus, a temperature in a showcase is increased. When an air temperature in the case is increased and the same temperature has arrived at a set temperature, a temperature switch closes a temperature contact 23a to finish defrosting and enter into cooling operation. In this case, a temperature contact 23b is also closed and the relay 25 is excited whereby the contact 25a is closed and illuminating lamps 11, 12 are lighted when the temperature in the case is highest upon finishing defrosting. On the other hand, another timer contact 22a is opened by a timer relay 22 after a shop is closed to extinguish the illuminating lamps 11, 12, which are lighted while the shop is opened.

Title: Cylinder head structure
Inventor: TAKEUCHI MAKOTO
IPC: F02F1/24
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a cylinder head structure capable of suppressing a crack generated on a top face of a head main body based on tensile force generated on the top face of a cylinder head main body. SOLUTION: On a top face 2 of a cylinder head main body 1, four guide holes 3 of a valve tappet are recessed per cylinder. At the center of the guide holes 3, a fuel injection nozzle or an ignition plug storing hole 8 is recessed. At a part partitioning each guide hole 3, a notched groove 12 is recessed so as to surround the storing hole 8. When the cylinder head main body 1 is fastened to a cylinder body with a head bolt inserted/passed into/through a bolt hole 9, radially outward tensile force for every cylinder is generated on the top face 2 of the head main body 1. As a result, this tensile force is disrupted by the notched groove 12 recessed on the top face 2 of the head main body 1 and does not act on a part 13 around the storing hole 8.  Therefore, a crack generated in the part partitioning the guide holes 3 and the storing hole 8 which has been a conventional problem is suppressed.
