Title: Optical wavelength multiplex recording and reproducing device
Inventor: SEYA MASATOMO
IPC: G11B7/00
Filed: 1987-06-19
Abstract: PURPOSE:To control the wavelength of a light source and to reproduce data of high reliability by detecting the phase of the output of a detector of a hole position mark where data having a reference wavelength is recorded by frequency modulation of the light source. CONSTITUTION:The light from a light source 10 modulated with a certain frequency by a high frequency oscillator 24 passes a collimator lens 12, an optical deflector 13, and an objective lens 14 to become a fine spot and is projected to a selected storage element 16 on a medium 15. The light reflected on the hole position mark recorded on the medium 15 is demultiplexed by a mirror 20 and is detected by a photodetector 21. This output is applied to a phase detector 22, and the output of the oscillator 24 has the phase detected as the reference. The detection output is applied to a wavelength adjuster 26 to perform the servo control, and thereby, the wavelength of the light source 10 always coincides with that of the objective hole. Thus, data of high reliability is reproduced.

Abstract: PROBLEM TO BE SOLVED: To provide the mounting method of a semiconductor element, wherein in the connection of the semiconductor element with a wiring board, a reduction in the reliability of the connection due to the residues of a flux is never generated. SOLUTION: In a mounting method, a semiconductor element 1 and a wiring board are previously heated at a prescribed preheating temperature and one part of an oxide film covering the surfaces of solder bumps 3 can be previously broken by pressure welding the element 1 to the board 2.

Title: Exhaust quantity measuring device for engine

IPC: F02B77/08
Filed: 1994-06-14
Abstract: PURPOSE:To realize compatibility of shortening of a measuring time and measuring accuracy by providing a flow rate sensor, a crank angle sensor, and a controller for calculating an exhaust quantity of an engine on the basis of a full stroke volume and the number of cylinders. CONSTITUTION:A flow rate sensor 30 is communicated with the inside of an engine cylinder. A crank angle sensor 70 detects a crank angle theta of a crank rotated in a compressing or expanding stroke. Signals output from the flow rate sensor 30 and the crank angle sensor 70 are sent to a controller 80. A full stroke volume Vc of a measuring cylinder is obtained on the basis of the output signals. An exhaust quantity of an engine is calculated based on the full stroke volume Vc and the number of cylinders. The full stroke volume Vc is determined on the basis of the calculated results of three simultaneous equations, where different values are substituted for theta. In the equation, D represents a bore diameter of the cylinder; (r), a radius of a crank arm; and Lc, a length of a connecting rod. Consequently, it is possible to shorten a measuring time and enhance measuring accuracy.

Title: Electron beam exposure apparatus
Inventor: YAMABE MASAKI
IPC: G03F1/54
Filed: 1981-09-30
Abstract: PURPOSE:To automatically correct a change in the divergence angle of an electron beam  emitted from the electron gun and to permit proper exposure even with brightness being  changed due to correcting operations or a change with the lapse of time by an apparatus wherein the divergence angle of the electron beam is detected, the amount of electron beam  irradiated to the sample is measured and a deflecting speed of the electron beam is changed. CONSTITUTION:The divergence angle is measured by detecting the current density profile of a  formed spot of an electron beam 12 irradiated onto a beam forming aperture 5 with a reflected electron detector 47. A bias controller 29 judges whether correction is needed or not based  on two data from a second comparator 28 and a processing circuit 30, and calculates a change  width of bias resistance and the direction thereof to apply thus calculated results to a bias  driving circuit 37. With this, the angular profile correction process to vary the bias resistance  is completed. The amount of electron beam is measured by a Faraday cup 44 disposed on a stage 46. The output of the Faraday cup is amplified by a current/voltage conversion amplifier 48, while reference frequencies are applied to a multiplier 17 from a reference frequence  register group 18. The deflection frequency with which the pattern is divided into rectangular  froms for exposure is properly selected, so that the actual exposure amount becomes always  constant. The deflection value is applied to a deflecting coil 10 via a deflection amplifier 23 to  vary a speed of electron beam.

Abstract: PURPOSE:To get information of electrons (a band structure, chemical bond state and elemental species) of energy deeper than information obtainable from a tunnel current in the case of no light irradiation b detecting an electron in a sample excited by a monochromatic light as tunnel current using a scanning tunneling microscope. CONSTITUTION:A tungsten chip 22 is brought near to a sample 22 to adjust the space between a chip and the sample such that tunnel current becomes 1nA at a fixed tunnel voltage, for example, at 1V. Next, while light from a light source 21 irradiates the surface of a sample, it scans the chip 22 on x-y face (in parallel with the surface of the sample), and this feed back loop is turned off at each fixed quantity of horizontal displacement to stop the chip 22, and by sweeping at a chip voltage within the range from, e.g. -3V+3V to measure a tunnel current, the measurement is stored in memory. Next, the measurement which is the same as above is repeated in the same region without irradiation of light so that distribution of electron density of deep energy can be detected by obtaining the difference between irradiation and non-irradiation of a tunnel current at each measuring point.
