Title: Particle size distribution measuring apparatus
Inventor: OYA SAMON
IPC: G01N15/02
Filed: 1991-03-27
Abstract: PURPOSE:To achieve a decrease in error of measurement of a particle size distribution by monitoring a ratio between a quantity of a laser light before irradiation of a group of fine particles, a quantity of a zero-order light not diffracted or a quantity of the light diffracted after the irradiation of the group of fine particles to allow the learning of whether the generation of a multiple scattering is within an allowable value or not. CONSTITUTION:Laser light 2 emitted from a light source 1 is made to irradiate a mirror 3 and a thereof is reflected to detect a quantity of the light with a photo detector 4. On the other hand, the light 2 transmitted through an mirror 3 is collimated to irradiate a group 7 of fine particles contained in the spraying of a fuel or the like and a part thereof is condensed with a lens 8 after the diffraction thereof while the other part thereof is reflected with a mirror 9 and the zero-order light alone passes through a pinhole plate 10 to detect the quantity of the lignt with a photo detector 11. Regarding the quantity of the light detected with the detectors 4 and 11, the ratio is calculated with an arithmetic circuit 5 to be compared with a specified threshold. When the ratio is smaller than the threshold, the generation of multiple scattering is regarded as exceeding an allowable level and an alarm sound is emitted.

IPC: H01L21/60
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To produce a small-diameter via hole with high accuracy at low cost by the following method: a photosensitive resin composition layer containing a photoinitiator is formed, and active or chemical ray is irradiated to an image, then a negative pattern is formed on the surface of a metallic foil by development, and finally patterning is performed by the photoetching method. SOLUTION: A photosensitive resin composition layer is formed on the surface of a metallic foil containing at least one photoinitiator selected among titanocene compounds represented by formulas. Then, photosensitive films for photoetching are laminated on both sides of a copper foil having a polyamide- imide pattern, and are exposed to light and developed to form a negative pattern. Next, the copper foil is photoetched for patterning so as to obtain a film carrier. Good adhesion between the metallic foil and film makes it possible to produce a small-diameter via hole with high accuracy. R11 through R20 in the formulas are each a hydrogen atom, a halogen atom, and an alkoxy or heterocyclic group with carbon numbers of 11-20.

Abstract: PURPOSE: To perform stable temperature control with little temperature change and to restrain the shortening of the life of a switching element by changing the order of turning on and turning off a heater in every cycle by a heater control means. CONSTITUTION: Since an LED 53b is not turned on in the case the 1st output port Pa of a CPU 34 is at a low level, that is, it is turned off, a main heater 18c is not turned on. In the case the output port Pa of the CPU 34 is at a high level, that is, it is turned on, an LED 53G is turned on and the main heater 18c is turned on. In such a case, all is kept being turned on during a heater driving cycle till exceeding the controlled temperature, and heaters 18c and 18d are turned off at the time of exceeding the controlled temperature, then an off-state is continued until the temperature thereof becomes equal to or under the controlled temperature again. In the case it is lower than the controlled temperature, the heater is turned on by decreasing the on-time of the heaters 18c and 18d in the heater driving cycle by 10%.  At such a time, the order of on/off is necessarily alternately executed, so that the number of turning-on times is reduced.
