Title: Second harmonic wave generating element and its production
Inventor: YAMAMOTO YUKIHIRO
IPC: H01S3/109
Filed: 1994-04-28
Abstract: PURPOSE:To produce a second harmonic wave generating element which lessens scattering loss of light generated in case of respective segments of a square shape, is free from leaking light and has high conversion efficiency by forming the respective segments to a lens shape. CONSTITUTION:The scattering loss of the light generated in the case of the respective segments of the square shape is lessened by forming the respective segments to the lens shape even if a single crystal of lithium niobate(LN) or lithium tantalum (LT) is used. More specifically, non-polarization inversion regions and polarization inversion regions having a higher refractive index than the refractive index of the bulk of the lens molds or the polarization inversion regions or non-polarization inversion regions having the higher refractive index than the refractive index of the bulk of the lens molds are alternately formed to the lens shape in the segments shape on the single crystal z plate 1 consisting of the LN or the LT. There are no differences in the refractive index between the polarization inversion regions and the non- polarization inversion regions at the time the polarization inversion is executed by impression of the voltage and, therefore, optical waveguides 2 are newly set. In such a case, the lens type optical waveguides 2 may be arranged at proper periods.

Title: Selecting method for semiconductor parts
Inventor: TANAKA MINORU
IPC: G01R31/26
Filed: 1979-09-03
Abstract: PURPOSE: To highly accurately and speedily select defective semiconductor parts without a bad effect on goods parts by applying a reverse bias to the semiconductor parts such as a transistor to detect a noise signal generated then.  
     CONSTITUTION: From a power source 1, a reverse voltage is applied to the transistor 3 as the semiconductor parts being measured. The base and emitter of the transistor 3 are short-circuited, and the DC bias is applied to the base and collector so that the P-N junction of the transistor 3 is reverse-biased. The collector of the transistor 3 is connected to a frequency spectrum analyzer 5 through a capacitor 4. The current supplied for the transistor 3 is controlled so that the transistor 3 outputs the signal as the noise signal in the breakdown region of the transistor 3, and the noise signal is measured by the frequency spectrum analyzer 5. This permits defective parts to be speedily measured and selected without applying stresses such as a high temperature and a temperature cycle on the semiconductor parts.

Filed: 1992-05-01
Abstract: PURPOSE:To send a message to a receiver side facsimile equipment through the use of a DTMF signal by providing a DTMF signal detection means and a conversion table in the system. CONSTITUTION:The facsimile equipment as a communication terminal equipment used for a receiver side is provided with a DTMF signal detection means 10 detecting a DTMF signal used as a pushbutton signal and a conversion table 11 converting a DTMF signal pattern into a character.

Filed: 1990-04-26
Abstract: PURPOSE:To suppress a current to a power system from a private power generating equipment of a customer system at the time of a short circuit trouble at the side of the power system by generating voltage, which corresponds to a difference between output terminal voltage at normal time of the private power generating equipment and linkage point voltage detected by a voltage detecting means, in additive polarity from an inverter relating to the linkage point voltage. CONSTITUTION:Linkage point voltage VS is always detected by a transformer 13, and an inverter 11 is controlled based on the linkage point voltage VS detected by the transformer 13, in a control circuit 10. As a result, voltage, which corresponds to differential voltage between output terminal voltage at normal time of a private power generating equipment 1 and the linkage point voltage VS detected by the transformer 13, is generated in additive polarity from the inverter 11 to the linkage point voltage VS through a coupling transformer 12. In this way, a current to a power system II from the private power generating equipment 1 of a consumer system I can be suppressed at the time of generating a short circuit trouble of the power system II.

Filed: 1993-05-14
Abstract: PURPOSE:To separate multiple sheets of documents while maintaining a secure separatable range of conventional system by stopping the upper parts of multiple loaded documents just before a separation part by providing a document restricting member. CONSTITUTION:A restriction member 1 rotatable in vertical direction relative to a document surface is provided on the upstream side from document separation parts 105c and 105d. The member is provided with two surfaces one of which 6 restricts multiple sheets and the other of which 7 passes several sheets, and a frictional means is provided on each surface. Also an exciting means 2 is provided at the upper part of the restricting surface 6. By this, the upper parts of the multiple sheets of documents are stopped by the restricting surface 6, and several sheets of documents 10 pass over the slanted surfaces 7 of the lower parts of them. When the number of documents is less, the restricting member 1 is raised, and the document 10 passes under it. In this case, the angle theta1 between the restricting surface 6 and a document stand 129 is set at 30 deg.<theta1<120 deg., and the angle theta2 between the document stand 102 and the slanted surfaces 7 is selected from 0 deg.<theta<theta1. Thus the documents can be separated easily because the number of documents exceeding a specified one is never fed to a frictional separation part.

Title: Damping characteristic controller
Inventor: YAMAMOTO MASANORI
IPC: B60G17/015
Filed: 1994-05-26
Abstract: PURPOSE:To control changes in maneuvering stability and comfortableness without a cost increase based on a chance in tire air pressure by detecting air pressure of the tires of wheels and, when detected air pressure is high, making a damping characteristic lower than when air pressure is low. CONSTITUTION:A suspension supporting member which supports axles 18, 20 to which right and left front wheels 10, 12 and right and left rear wheels 14, 16 are attached is provided with shock absorbers 26-29 whose damping coefficient is adjusted by actuators 32-35. Tire pressure sensors 40-46 are provided to detect, air pressure of the tires of respective wheels 10-16. Since comfortableness deteriorates as tire pressure becomes higher as a result of a higher longitudinal spring coefficient and the subsequent higher resonance frequency, the damping coefficient is reduced by a damping characteristic controller 150 when the tire pressure detected by tire pressure sensors 40-46 is high, thereby preventing comfortableness from becoming deteriorated. When tire pressure is low, the damping coefficient is controlled so as to be higher.
