Title: Laminated ferrite inductor device and manufacture therefor
Inventor: UCHIKOBA FUMIO
IPC: H01F27/00
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To prevent improper insulation between outer terminal electrodes caused by expansion in plating by adjusting a ferrite surface between the outer terminal electrodes to have a specific surface roughness. SOLUTION: Printed ferrite green sheets are so laminated in a predetermined order as printed patterns on adjacent sheets to become an U letter form which faces each other, are heated and clamped, after that are cut to form a chip, are detached from a binder and are made heat treatment to form a sintered compact. After the sinter treatment the obtained chip is ground, metallic paste such as silver is applied at a predetermined part and outer terminal electrodes are formed by baking treatment. Next, the ferrite surface between the outer terminal electrodes is ground to adjust at a predetermined roughness, after that metallic coating treatment is made by electrolytic plating. In this case center line mean roughness (Ra) is adjusted to be in a range of 0.01 to 0.1 μm or preferably 0.02 to 0.05 μm.

Title: Multichannel recording method
Inventor: TANAKA MASATO
IPC: G11B27/02
Filed: 1980-07-26
Abstract: PURPOSE:To eliminate the rewriting of the discriminating signal and thus to prevent an error during the synchronous recording or punch in/out editing which is independent with every channel, by recording the rewritable discriminating signal with every channel and on the same track as the data of the corresponding channel. CONSTITUTION:The digital signal containing the control bit showing an on-off of emphasis is supplied to an encoder 4 via an input circuit 3 to produce the signal containing a flag bit functioning as a discriminating signal that shows whether a data is emphasized in the data synchronous signal positioned at the head of each block of a PCM data. This discriminating signal is distributed by a demultiplexer 7 to the data track of each channel and based on each format and then recorded by a recording head HR after a modulation 9. In such way, the rewritable discriminating signal is recorded on the same track as the PCM data of the corresponding channel. Thus the rewriting of the discriminating signal can be eliminated to prevent the occurrence of an error during the synchronous recording or punch in/out editing which is independent with every channel.

Title: Protective circuit of switch mode power supply
Inventor: CHIYUN SHIN UU
IPC: H02H7/12
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To realize the protective circuit for switch mode power supply easily by switching a power supply to stand-by mode upon occurrence of short circuit. SOLUTION: When a line 12 is short-circuited, a first converter 16 breaks the power supply voltage to a control stage 20 and thereby a signal S disappears along with a signal S'. Consequently, a switch mode power supply controller 11 switches a switch mode power supply 10 to stand-by mode. Similar operation takes place when a line 13 is short-circuited. When a line 14 is short-circuited, a transistor included in a second converter 17 switches a breathing signal to ground. Consequently, the signal S is blocked and the protection of controller 20 is triggered. Consequently, a stand-by mode being controlled by means of the switch mode power supply controller 11 is obtained.

Title: Automatic slicing value setting device for graphic reading device
Inventor: KIMURA YOSHINORI
IPC: G06K9/38
Filed: 1991-04-09
Abstract: PURPOSE:To automatically set an appropriate slicing value depending upon the printed density of a graphic. CONSTITUTION:When the density of a graphic registered in a recognition circuit 2 and printed on a form 5 is higher than a slicing value set in a converter 1, the converter 1 reads the graphic and outputs an electric signal. The circuit 2 recognizes the graphic on the form 5 based on the electric signal and compares the recognized graphic with a preregistered graphic and, when both graphics do not coincide with each other, outputs a prescribed signal to a slicing value control circuit 3. Upon receiving the signal, the circuit 3 sets a new slicing value and gives the set value to a converter control circuit 4. The circuit 4 controls the converter 1 to read the graphic on the basis of the newly given slicing value. The converter 1 again reads the graphic on the basis of the new slicing value. Such operations are repeated until the graphic recognized by the circuit 2 coincides with the registered graphic and, finally, an appropriate slicing value is set.
