Patent JP-H0380601-A (JP)
Title: Microwave converting circuit
Inventor: IKEDA HIROYUKI
IPC: H01P3/08
Filed: 1989-07-26
Abstract: PURPOSE:To eliminate the need for a connection wire, prevent reflection characteristics from deterioration, improve high-frequency characteristics and enhance reliability by connecting multi-layered microstrip lines which are different in height by a coplanar line which is formed in a staircase shape. CONSTITUTION:The multi-layered microstrip lines 1 and 2 which are different in height are connected by the coplanar line 6 which is formed in the staircase shape. Therefore, when a high-frequency signal is propagated to the microstrip line 2, an electric field is produced between the microstrip line 1 and a ground conductor 3 and an electric field is produced next between the connected coplanar line 6 and installation patterns 7-1 and 7-2. Further, the high-frequency signal produces an electric field between the microstrip line 2 and ground conductor 3, connections can be patterned by the coplanar line 6 in the staircase shape, and the microstrip lines 1 and 2 can be connected without any deterioration in reflection characteristics. Consequently, reflection characteristics at connection points are improved and the high-performance, high-reliability microwave converting circuit is obtained.

Abstract: PURPOSE:To align the positions of a mask and a wafer with a high precision by detecting with an off axis microscope the alignment marks which are formed by the utilization of a phase shifting method. CONSTITUTION:Reticle alignment marks 105L and 105R provided with an area where the phase of transmittable beams is inverted are arranged in a given position on a reticle 11 and also a reticle set mark 12 is arranged on a reticle 11 when a semiconductor circuit pattern on the reticle 1 is projected by a projection lens 4 onto the photosensitive layer on a wafer 2 for exposure. The reticle alignment marks illuminated by the projection lens 4 are formed as a latent image on the photosensitive layer arranged in a given position of a stage 5 where the wafer 2 is mounted, or as the respective images of the marks on the wafer 2, through a reticle illuminating optical system 13. Then, these images are detected by a CCD 48. In accordance with the result of such detection, the reticle 1 is shifted to a reticle stage.

Title: Sound information recording device and magnetic recording medium recorded with sound information
Inventor: UMEMOTO MITSURU
IPC: G11B20/02
Filed: 1991-07-09
Abstract: PURPOSE:To listen to a sound for an ordinary person even when the reproducing speed is substantially made double and to drastically shorten a time for collecting information by lowering frequency of a sound signal of which repro ducing speed is made fast in a magnetic recording medium in which sound information is already recorded. CONSTITUTION:As a result of studying easiness for listening in the case of increasing a reproducing speed, it is found that though the reproducing speed is fast, when sound frequency, that is, tone is lowered, easiness for listening can be realized. Therefor, by using a double speed reproducing device l, a master magnetic tape MO in which sound is recorded with a ordinary set recording speed is loaded in this device, and sound information is reproduced with a double speed of the set recording speed. Thereby, width of the sound signal is made half, that is, half temporally, but sound signal of double frequency can be obtained. However, since contents of sound by this signal can hardly be listened, a signal processor is connected to the device 1, frequency of the sound signal is calculated and made half, and recorded in a magnetic tape M1 loaded in a recorder.

IPC: G06T1/00
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To reduce the cost of turn table part and to satisfactorily read an original at any arbitrary rotating angle position. SOLUTION: A rack gear member 65 is stuck on the outer peripheral face of a disk-shaped turn table part 52.

Abstract: PURPOSE:To avoid the intrusion of a liquid between a container and a label and the coming-loose of the label therefrom by fitting the cylindrical label consisting of the uniaxially stretched resin film having its inner adhesive side printed over the container whose outermost layer consists of a heat resisting resin layer. CONSTITUTION:A cylindrical label 2 consisting of the uniaxially stretched resin film having its inner adhesive side printed is fitted over a container 1 whose outermost layer consists of at least a heat resisting resin layer at a thermal deformation-causing temperature not below 80 deg.C.

Abstract: PURPOSE:To determine quantitatively the volume of a very small quantity of liquid by disposing a light source and a one-dimensional image sensing device with the transparent part of a liquid flow passage in-between and measuring the change in the quantity of the light by the liquid passing through the flow passage. CONSTITUTION:Fresh water is filled in a sampling nozzle 1. Some air is first sucked by a nozzle 1 then a serum sample 10 is sucked. The sample 10 is sandwiched by two air layers 11, 12 and is thus held. The sample 10 is positioned in the optical path of the parallel rays emitted from a light emitting source 2 and regulated by a lens 3. The light transmitted through the sample is sensed via a light guide 4 by a one-dimensional image sensing device 5. The volume of the sample 10 is calculated from the data inputted from an external input device 7 by an arithmetic processing part 6 and is displayed on a display device 8. The volume of a very small quantity of the liquid is thus quantitatively determined.

Abstract: PURPOSE:To improve efficiency by providing current blocking layers separated from each other of a first conduction type which are formed on the top face of a stripe-like protruding part and on the surfaces of an upper clad layer respectively, and by providing a contact layer of a second conduction type which is in contact with the stripe-like protruding part partially, and further, by obtaining a satisfactory bottlenecking of a current. CONSTITUTION:On n-type GaAs current blocking layers 20a, 20b, 20c, a p-type GaAs contact layer 22 of about 4.5mum in thickness is formed so as to embed a stripe-like protruding part in itself. The p-type GaAs contact layer 22 is in contact with a p-type clad layer 16 on the side faces of the stripe-like protruding part, and such current paths as shown with arrows are formed. In this manner, by reducing the thickness of the p-type GaAs contact layer 22 at its middle, the beam is confined in the lateral direction. By the stripe-like protruding part separating the three n-type GaAs current layers 20a, 20b, 20c from each other, bottlenecking of a current is performed. Therefore, the satisfactory confinement in the lateral direction of a beam and the satisfactory bottlenecking of a current can be performed, and a semiconductor laser device having a low threshold current and a high efficiency can be realized.

IPC: G03C7/42
Filed: 1988-08-05
Abstract: PURPOSE:To improve the picture stability after processing the subject material and the desilverization of the material, and to make it possible to rapidly processing the material by incorporating at least one kind of a polymer coupler in the material, and processing the obtd. material with a specified processing solution. CONSTITUTION:At least one kind of the polymer coupler is incorporated in the photosensitive material, and the processing solution having bleaching ability contains a ferric salt of a 1,3-diaminopropane tetraacetic acid of >=0.2mol/l and has pH of a range of 2.5-5.5. The polymer coupler may be incorporated in any one layer of photographic constituting layers, preferably a photosensitive emulsion layer or its adjacent layer in an amount of 0.01-1.0g per 1m<2> of the photosensitive material. When the additional amount of the ferric salt of 1,3-diaminopropane tetraacetic acid is <0.2mol/l, the bleaching speed of the material rapidly slows down, and the stain of the material increases after processing it. Thus the sharpness of the material is improved, and the processing time of the material makes it possible to shorten, and the stability of a picture after processing the material is improved, and the faulty desilverization of the material is prevented.
