Title: Lead frame and its manufacture
Inventor: YOKOZAWA MASAMI
IPC: H01L23/495
Filed: 1980-11-14
Abstract: PURPOSE:To prevent deterioration of insulating characteristics in the case of cutting a lead frame by a method wherein a semiconductor supporting region of a lead frame is built as a three-layered structure with an intermediary of an insulating layer, and a slit is provided in the first metal layer. CONSTITUTION:In a lead frame which consists of the first metal layer which forms a supporting region for semiconductor substrate provided with a slit 17, and the second metal layer 14 with an intermediary of an insulating layer 13 which can not be deteriorated in electrical insulation in spite of heat-treatment such as polyimide resin or the like, the fore-mentioned slit 17 divides into two regions of an adhesing region 61 for a semiconductor substrate and a not-adhesing region 62 in this structure. By this constitution, even though there exist  shortcircuiting fault between the first metal layer 12 and the second metal layer 14 by burrs to be generated at the time of cutting the lead frame, shortcircuiting does not take place because of electrical segregation at the slit.

Title: Speaker system
Inventor: MIHASHI TAKASHI
IPC: H04R3/00
Filed: 1991-07-02
Abstract: PURPOSE:To allow one signal processing means to select a different directivity by applying the changeover control of a phase of an output signal to a central speaker unit in phase or in opposite phase to the output signals of speaker units at both ends. CONSTITUTION:A signal processing means 101 outputs an output signal S to speaker units 102, 104 at both ends and an output signal S* in opposite phase to the signal S to a central speaker unit 103. When the output signal S* is given to the central speaker unit 103, the sound around the unit 103 is cancelled by a sound V* corresponding to the signal S* and a sound V corresponding to the signal S to take a double peak directivity. With the output signal S given to the unit 103, the directivity is a directivity eminent on the speaker axis. Thus, the speaker equipment is provided with a different directivity through selection.

Title: Laser output setting method for optical disk recording and reproducing device
Inventor: SAWADA MICHIYOSHI
IPC: G11B7/125
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To evade an influence of a characteristic of a monitor diode and to obtain a best reproducing output by moving an optical pickup to a signal unrecorded area on a disk, detecting a reflection light quantity in the signal unrecorded area, using the detected light quantity as a reference value and adjusting the reproducing output. SOLUTION: A quantity of a beam reflected by the disk 1 is detected by a reflection light quantity detection circuit 14 to be stored in a memory circuit provided in a system control circuit 9 as the reference data. When a position of a light beam becomes a recording start position of a test signal, the recording operation of the test signal is started by a recording output, and the reproducing output at a recording start time is made larger than the reproducing output set when the signal in the signal unrecorded area is read to be performed. The quantity of the beam reflected from the disk 1 of the light beam emitted by the reproducing output is detected by the reflection light quantity detection circuit 14 whenever a reproducing output of a laser is changed, and output lowering operation is stopped when the light quantity becomes equal to the reference data.

Title: Support pressure control mechanism in support pressure adjusting type body supporting device
Inventor: SAITO SHUICHI
IPC: A61G7/00
Filed: 1990-06-20
Abstract: PURPOSE:To prevent support bodies from dropping and average the actions of the support bodies by using a control means to operate a pressure sensor for scanning at the renewal of operating conditions so as to extract support bodies with support pressures higher than predetermined pressure, and actuating a drive means at the next renewal when there are no adjacent support bodies with support pressures higher than the predetermined pressure. CONSTITUTION:The body of a patient is supported by the body supporting face of each of a number of elastic supporting bodies 4. A control means 16 measures support pressure corresponding to each support body 4 using a pressure sensor 15 and renews operating conditions every predetermined time. The support pressure of each support body 4 is first scanned and those support bodies 4 which show support pressures higher than predetermined pressure are extracted. The control means 16 judges whether or not those support bodies 4 which are adjacent one another in the longitudinal and cross direction and which have already been scanned are selected, and switches to a selected state only if they are not selected, and operates a drive means at the next renewal. Therefore, those support bodies 4 which are adjacent one another in the longitudinal and cross directions are not allowed to fall simultaneously, thus preventing generation of a dent that could occur when those support bodies fall simultaneously. When allowed to drop each support body 4 its support pressure is lowered and is not therefore extracted at the next renewal and those support bodies 4 which have been extracted but not selected at the previous renewal are selected so as to average the actions of the support bodies 4.

Abstract: PURPOSE:To discriminate quickly and exactly welding strength, and to improve the work efficiency by reading in advance welding waveform data, determining a nondefective tolerance by setting a reference waveform based on said data, and discriminating the quality of the welding waveform data. CONSTITUTION:When a current is supplied from a welding power source transformer 5, the current flows to metallic wires 3, 4 through each welding electrode 1, 2, and the metallic wires 3, 4 are welded.

This digital signal corresponds to a voltage if a voltage waveform of each welding operation, and on the other hand, a nondefective waveform in case when said welding has been executed with sufficient strength is stored in advance as a reference waveform in a memory part 8. This reference waveform and the measured waveform are compared by voltages of plural sample points.

Inventor: OGAWA KAZUO
IPC: G01N33/48
Filed: 1983-09-05
Abstract: PURPOSE:To make it possible to perform accurate measurement in a short time without interference from other materials even in any concentration region of fibrinogen, when the fibrinogen in blood plasma is determined by a salting out method, by adding casein to a reagent for the salting out method. CONSTITUTION:To a reagent used for salting out fibrinogen in blood plasma, casein of 0.0002-0.005wt% with respect to the total amount of the reagent is added. Thus interference by materials such as lipid, bilirubin, hemoglobin and the like in the blood plasma is excluded. Measurement can be performed accurately, especially in the low concentration region of the fibrinogen such as 60mg/ dl or less. The reagent for the salting out method comprises Na2SO4 and the like, a surface active agent, and an acetic acid buffer solution. The cost of the reagent is inexpensive, the time required for measurement is short, and special equipment is not needed. Therefore, the reagent is suitable for clinical examination for acute infections, malignant tumors, circulatory-organ diseases and the like.
