Title: Structure of nozzle for surface mounting component detachment use
Inventor: ISHII YOSHITAKA
IPC: H05K3/34
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To make it possible to detach efficiently an SMD without making a printed board and peripheral components burn by a method wherein the inside point part of a nozzle is made shorter than the size of the outside point part of the nozzle to give a step on a hot blow jet vent and at the same time, hot blow is made to jet toward the center part of an SMD main body. SOLUTION: Hot blow 4 sent in a nozzle part 10 is made to flow to the outside and inside point parts 12 and 13 of the nozzle part 10, in short, in the direction of a heated air jet vent 10a of the nozzle part 10 while being accelerated. The hot blow 4 is jetted more in the direction of the point part 13, which is made shorter than the point part 12, than the point part 12. From this reason, a BGA type SMD 11 receives the jetted heated air from all the directions. The heated air inevitably becomes easy to blow in the direction of the center of the bottom of the SMD 11, solders 9 connecting electrodes 11a arranged on the bottom of the SMD 11 with soldered pads 8 fused on a printed board 7 are efficiently made to dissolve in a short time and at the same time, the solders 9 are prevented from giving a thermal stress to other parts on the periphery of the SMD 11.

Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To produce a preform for an optical fiber having stable characteristics while preventing the characteristics from being changed at the intermediate treatment steps of its production process. SOLUTION: The preform for an optical fiber is produced by spraying the raw material of the optical fiber containing a dopant onto a starting base material S from a burner 2 for a core to accumulate a core base material in the axial direction, spraying another raw material of the optical fiber from a burner 3 for a clad to accumulate a clad base material and then dehydrating and sintering. The production repeating this procedure is carried out by measuring the distribution of the refractive indexes of the core base material of the base material produced with a preform analyzer 7, calculating the difference between the difference of the measured refractive indexes and the target difference of the refractive indexes using a sequencer 6, converting this difference into a correction value of the dopant supply amount and correcting the amount to be supplied to the dopant on the basis of the correction value through a regulator 5.

Title: Motor
Inventor: ICHIUMI YASUFUMI
IPC: H02K5/16
Filed: 1992-07-10
Abstract: PURPOSE:To obtain a highly reliable and inexpensive motor that is easy to work because it is less affected by variations in temperature of resin in the structure of a motor whose bearing retaining part is made of resin or the like.

Title: Communication unit, communication system, communication method and storage medium
Inventor: ICHIMURA HIROSHI
IPC: H04W4/18
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To provide a communication unit where an image to be transmitted is changed into a transmission (transfer) image or a display image on a communication opposite party, depending on an operating state (a state of use). SOLUTION: When a PHS section 203 receives data, processing is branched depending on the operating mode. In the case of a telephone mode, since the communication unit has only a telephone transmission reception function, the unit transmits an image denoting 'image transfer in preparation' that is able to find out prepared in advance in a flash memory 213. Thus, a destination unit is able to find out the state of a terminal on a sender side. In the case of a camera mode, whether a photographing image or a photographed image can be sent is discriminated. When setting is made to permit transmission of the image, the image that is being photographed or has been photographed is transmitted (S608).

Filed: 1990-07-13
Abstract: PURPOSE:To enhance reliability by a method wherein, at an erasure operation, carriers of a floating gate are released by a tunneling operation between the floating gate and a well. CONSTITUTION:When a data is written into a memory M1, a positive 'H' level potential is applied to a selected control gate line CG1 and a bit line BL; and a residual common source line SS, a p-type well nonselective control gate line CG2 and a nonselective bit line are all set to 0V. Then, when the data is erased collectively, all the control gate lines CG's are set to 0V, and a positive 'H' level potential which is boosted to be sufficiently high is applied to a substrate, a p-type well and the bit line BL. Thereby, in all memory cells, electrons are released, by a tunneling effect, to the p-type well from a floating gate. When the data is erased collectively and is written, a breakdown is not caused on the surface part of a source diffusion layer or a drain diffusion layer, and a data retention characteristic is enhanced.
