Title: Semiconductor device
Inventor: KAMATA CHIYOSHI
IPC: H01L23/12
Filed: 1989-09-20
Abstract: PURPOSE:To prevent the deterioration of a waveform by a method wherein a transmission line for making an exchange of an electrical signal with one terminal provided on a semiconductor chip is constituted into a hierarchical structure consisting of two layers or more and the upper and lower layer transmission lines of the transmission line are connected to each other by at least two pieces or more of connection conductors. CONSTITUTION:One end of a bonding wire 2 is connected to a bonding pad formed on a semiconductor chip 1. A transmission line 13 constituted into a two-layer hierarchical structure is connected to the other end of the wire 2. This line 13 constituted into a two-layer hierarchical structure is constituted of upper and lowe layer transmission lines 31 and 32 and via metals 41 and 42, which are connected with the lines 31 and 32 at both ends of each via metal. That is, as the line 13 is constituted into a two-layer hierarchical structure and the lines 31 and 32 are provided in such a way that they are connected to each other by two pieces of the metals 41 and 42, a transmission path can be made into two kinds like transmission paths A and B. Thereby, the deterioration of a waveform stops generating.

Filed: 1991-09-25
Abstract: PURPOSE:To detect a substantial fault of a generating equipment specific to a terminal station without mis-discrimination of a decreased output of the generating equipment not solved and caused by deterioration in the natural environment as a fault. CONSTITUTION:A control circuit 12 of a radio base station 2 compares histories of output stages of a solar battery 3 in all radio terminal equipment stations 1 stored in a storage element 13 and sent from the plural radio terminal stations 1 by a periodic monitoring to confirm whether or not an output decrease takes place in a solar battery 3 of only a specific radio terminal station 1.

Title: Synchronizing signal generation system
Inventor: MIYAUCHI NAOKI
IPC: H04N5/06
Filed: 1994-10-11
Abstract: PURPOSE: To acquire a color synchronizing signal that is free from the color jitters and the phase drift by using an input SC(subcarrier) signal of high stability, if available, as an output SC signal and then using a reproduced SC signal of an internal oscillator output if the input SC signal is not available.

Title: Constant current circuit
Inventor: FUJIMOTO HIDETOSHI
IPC: G05F3/26
Filed: 1990-09-14
Abstract: PURPOSE:To obtain a large constant current output with the small power consumption by converting the collector voltage of a 1st transistor TR of a constant current mirror circuit into a current and supplying this current to the base where both 1st and 2nd TRs are connected to each other after amplifying the current. CONSTITUTION:A constant current mirror circuit consists of two TR Q1 and Q2. Then the TR Q3 and Q4 serve as the means which amplify the collector voltage of the Q1 set at the non-output stage side and supply the base current to a common base of both Q1 and Q2 through a constant current output terminal. Thus it is possible to supply a large base current to the Q2 set at the output stage side while reducing the collector current (reference current with current consumption Iref) of the Q1. Then a large constant current output is obtained.

Title: Phosphorescence spectrophotometer
Inventor: KIMURA MITSUYOSHI
IPC: G01J3/443
Filed: 1983-12-29
Abstract: PURPOSE:To use one spectroscope alternately as excitation-side and phosphorescence- side spectroscopes by using the one spectroscope as the excitation-side spectroscope when light is passed through a light intermitting part, and using said spectroscope as the phosphorescence-side spectroscope when light is intermitted. CONSTITUTION:Light from a light source 1 is passed through a light absorbing part 2, introduced to the light intermitting part 3, subjected to the intermitting action and introduced to the spectroscope 13. Since the spectroscope 13 is changed over to the excitation-side spectroscope, the light of some wavelength is taken out by diffraction, passed through a light absorbing part 5 and irradiated to a sample 6 as the excited light. If the sample 6 is excited for a fixed time, the part 3 intermits the light from the source 1. At this time, the spectroscope 13 is changed over to the phosphorescence-side spectroscope. Thereby, phosphorescence (b) is introduced to the spectroscope 13 through the part 5. The diffracted light is introduced to a detecting part 10 through a light absorbing part 9 and converted to an electric signal (c). The signal (c) is processed by a signal processing part 11 synchronously with a synchronizing signal (d) from a spectroscope controlling part 12. It is sufficient with only one spectroscope 13, the structure is simple and can be miniaturized.

Title: Image forming device
Inventor: TABUCHI TAKESHI
IPC: G03G15/02
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To obtain a stable image without density irregularity even when a device is used at a place where the change of ambient temperature is large. SOLUTION: When the temperature of an electrifying roller 2 or the temperature near it is changed because the ambient temperature of the place where the image forming device is installed is changed, a start-up time for electrification that electrifying potential on the photoreceptor 1 is stabilized after a voltage is impressed on the roller 2 is changed. However, the temperature of the roller 2 or the temperature near it is detected by a temperature detection sensor 20 and time required until an image is started to be formed on a photoreceptor 1 after the voltage is impressed on the roller 2 is varied so as to be optimized by a pre-electrifying time control means 5 according to the detected temperature. Thus, since the electrifying potential in one image can be fixed, the stable image without the density irregularity is obtained.

Title: Pressure-resistance reducing structure
Inventor: KURATA MITSUO
IPC: F15D1/12
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To sufficiently reduce the pressure resistance of even an angular object by forming a small notch in the position of the flow-receiving object where fluid separates, or just in front of it. SOLUTION: An object 2 which receives flow has, e.g. a square cross-sectional shape, with a square notch 3 formed like a step at each of the front angles of this square shape. By setting the small notch 3 to an appropriate size, a separating line of flow F which has temporarily separated from the front edge 6 of the small notch 3 interferes with a rear edge 7 just near it, causing a part of the vortex of a shear layer to converge to the small notch 3 to gradually form a strong vortex G. Since the vortex has a lower pressure than an external stream H, the flow is curved in such a way that its radius of curvature is decreased by the balance between a pressure gradient in the radial direction of the flow and a centrifugal force, causing the separating line of flow F to come into contact with portions near the rear end 7 again.  Therefore, the external stream H is also curved in such a way as to come close to the side 8 of the object 2 and to flow along the side 8. Therefore, the area of the backflow B of the object 2 is reduced appreciably, resulting in greatly decreased pressure resistance.
