Title: F type antenna
Inventor: SHIMAZAKI TETSUYA
IPC: H01Q9/30
Filed: 1999-12-13
Abstract: PROBLEM TO BE SOLVED: To provide an F type antenna capable of maintaining required performance even though the dimensions of the ground plate of the antenna is made small. SOLUTION: This antenna uses a rectangular printed circuit board. The antenna element of an F type conductor film and the ground plate of a rectangular conductor film are collectively formed on one face of the rectangular printed circuit board or the antenna element of an F type conductor film and the ground plate of a rectangular conductor film are formed on the one face and the other face respectively. A microstrip line is also formed from the feeding end of the F type conductor film to the edge of the ground plate on a face different from the face where the ground plate of the rectangular printed circuit board is formed. Even though the ground plate operates as ground for the microstrip line, the ground plate is formed so as to work not as ground but as an antenna element for the antenna element. The electrical length of the ground plate shows the most stable SWR characteristic when the electrical length is about 1/4 wavelength.

Title: Vacuum holding device for semiconductor device in printing of solder paste
Inventor: OGINO TADAO
IPC: B41F15/20
Filed: 1993-12-31
Abstract: PURPOSE:To prevent a semiconductor device from adhering to a printing mask by an adhesive force of a solder paste when the semiconductor device and the printing mask are separated from a form plate at a batch printing time of the solder paste for pads to a surface of the semiconductor device. CONSTITUTION:A vacuum suction stage 18 is set on a backup plate 17 of a working table 4 of a solder paste-printing apparatus. The interior of a vacuum drive chamber 20 of the vacuum suction stage 18 is vacuumized, thereby sucking and fixing each semiconductor device 1 positioned and stored in a storing hole 11 of an arrangement plate 10 to an suction face 25 by a vacuum suction force. After a solder paste is completely printed to the semiconductor device 1, a printing mask 6 and the semiconductor device 1 are separated from a form plate. At this time, a vacuum suction/fixing force to the semiconductor device 1 is larger than an adhesive force of the solder paste of the printing mask 6, and therefore the semiconductor device 1 is prevented from adhering to the printing mask 6 when separated from the form plate.

Title: Image-processing apparatus, image processing method and printing apparatus
Inventor: SOMENO MASAHIRO
IPC: B41J2/205
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To improve an image quality in long printing. SOLUTION: Image data separated to a plurality of pages and supplied from an application program is printed to a roll paper without providing a margin between pages, thereby printing in a large size, for example, a cross curtain or the like. A printer driver carries out a halftone process by an error diffusion method to the image data separated to the plurality of pages. When a normal mode is designated at this time, an error buffer is initialized at a time point of starting a new page. When a long mode is designated, the error buffer is not initialized. An error is accordingly diffused among different pages in the long mode. An image separated to the plurality of pages can be handled integrally in the halftone process and an image quality particularly in the vicinity of a boundary of pages can be improved.

Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To prevent a step-out or other troubles by detecting the exact position of a rotor of a brushless motor and making a proper changeover of excitation possible. SOLUTION: When switching the DC power from a DC power supply by switching elements of an inverter circuit 3 and then applying the switched DC power to a brushless motor 4, a control circuit 10 outputs a drive signal for chopping the switching elements of the inverter circuit 3, a chopping signal, and a control signal (changeover of the chopping) to chop the switching elements. Meanwhile, the control circuit 10 detects the position of a rotor 4a of the brushless motor 4 from position detection signals A, B, C output from a position detecting circuit 5 and then changes over the excitation of armature windings of the brushless motor 4, based on the detected position of the rotor 4a. In the position detection, the position detecting time intervals are counted.  Then, a next position detecting time is estimated based on the position detecting time intervals, and the on-state time and off-state time of the chopping signal near the estimated position detecting time are temporarily varied to make the induced voltage and the reference voltage cross each other and thus a correct position detection is made.

Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To make a fast scan with light over a wide range by allowing a specific resonator to resonate at the vibration from a driving part and vibrating a reflecting mirror, and making the scan with the light made incident on the reflecting mirror. SOLUTION: The base end of the resonator is fixed to a base and made to resonate to the vibration from the driving part and have torsional vibration and then the reflecting mirror is vibrated to make the scan with the light made incident on the reflecting mirror. The resonator satisfies G/ρ>=12×10<6> Pa.kg<-1> .cm<3> , where G is the lateral elastic modulus and ρ is the density. The value G/ρis increased within this range and then the natural vibration frequency of the resonator becomes large, so that the reflecting mirror can be vibrated fast. This range exceeds the G/ρ value of a metallic material such as iron and a large vibration frequency is obtained. Here, G/ρ can be increased by increasing the lateral elastic modulus G by holding the density ρ constant or decreasing the density ρ by holding the lateral elastic modulus G constant.

Title: Image forming device
Inventor: NISHIDO KAZUHIRO
IPC: G03G15/045
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To prevent deteriorated toner from remaining in a developing device and, therefore, to prevent secular image-density-decrease by composing so that when the number of sheets detected by a means which detects the number of sheets reaches a specific number, electric potential between a latent-image carrier and developer carrier which is outside an image forming area is increased. SOLUTION: A controller controls the entire system so that when the number of sheets counted by the counter 12b of the means 12 which detects the number of sheets reaches the specific number, the electric potential between the photoreceptor 1 and developing roller 4b which is outside the image forming area on the photoreceptor 1 increases. This prevents toner from sticking to the outside of the image forming area on the photoreceptor 1, and the toner is recovered by cleaners 6 and 11 without being used for image formation. That is, from the number of the transfer sheets 9 which have been used, the deteriorated state of the toner 8 is detected, and the toner in the developing device 4 is forcibly consumed before the toner deterioration advances.

IPC: G11B11/10
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To accurately reproduce data by preventing the occurrence of asymmetry due to influence of an external magnetic field, etc. SOLUTION: Based on an offset level detected based on a previously recorded regenerative RF signal of a test pattern, a laser power correcting value ΔP is obtained. Then, when an initial laser power value at the time of recording is denoted as P, two updated laser power values P as P=P±ΔP are set in accordance with polarity of an impressing magnetic field, and a light emitting output of a laser is performed by these laser power values P. Consequently, the influence of the external magnetic field upon the recording magnetic field to be impressed upon a disk is canceled.
