Title: Method for detecting frequency modulation characteristic of semiconductor light emitting device
Inventor: OGITA SHOICHI
IPC: H01S5/00
Filed: 1988-08-10
Abstract: PURPOSE:To detect the frequency modulation characteristic of light highly accurately by intermittently modulating a semiconductor light emitting device with a specified modulating frequency, generating the difference in optical paths relatively so that the modulated part and the non-modulated part of the light that is divided into two pats are overlapped on each other, and mixing the light beams. CONSTITUTION:A DC voltage is applied on a semiconductor laser 10 from a load power source 12. An AC oscillator 14 is connected to the intermediate point therebetween through a capacitor 16 and a switch 18. The switch 18 is turned ON and OFF with a specified frequency. Thus output laser light A from the semiconductor laser 10 undergoes frequency modulation intermittently. The light is divided into two parts through a half mirror 20. The difference in optical paths is generated with half mirrors 24 and 26 so that the modulated part of one light and the non-modulated part of the other light are over lapped. The light beams are mixed in a half mirror 22. The mixed laser light is detected with a photodetector 28, and the frequency modulation efficiency is obtained. In this way, the frequency modulation characteristic can be detected simply and highly accurately.

Title: Manufacture of solid-state image-pickup device
Inventor: FUJIKAWA KAZUHIDE
IPC: H04N5/335
Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To improve transfer efficiency of electric charge by ion-implanting N<+> -type impurities into an area wider than a channel region of a vertical transfer register, forming electrodes of the vertical transfer register and a horizontal register and implanting P<+> -type impurities into the electrodes in a self-alignment manner. SOLUTION: At the time of forming a channel 22 of a vertical transfer register 12, N<+> -type impurities are implanted into the channel 22 over a width of an extension TR' of a transfer electrode of a horizontal transfer register 14 or wider. Then an electrode 23-4 of a fourth phase of the register 12 and a pair of electrodes 25-1, 25-2 of the register 14 are formed. Thereafter P<+> -type impurities are implanted into the electrodes 23-4, 25-1, 25-2 in a self-alignment manner, and the N<+> -type impurities migrating from the electrodes are offset by the P<+> -type impurities. Thus it is not necessary to take the variation of alignment accuracy into account at the time of manufacturing on a V-H transfer part 13 so as to increase the width of the channel 22 by this amount, so that the efficiency of the V-H transfer can be improved.

Title: Connector-integrated sensor
Inventor: AKIMOTO RYOSAKU
IPC: G01K7/22
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To easily adjust the thermal time constant of a sensor and to replace an arbitrary kind of connector so as to be used by a method wherein the sensor which is connected to a terminal at the connector is buried, via a filler, into a cylindrical cover and a connector body is coupled integrally to the open end side of the cover. SOLUTION: A sensor 3 which is connected, via a lead wire 2, to a terminal 8 at a connector 1 which is available on the market is arranged inside a cylindrical cover 4 one end of which is opened. Then, a body 6 at the connector 1 is bonded to the open end side of the cover 4, a filler 5 is filled into the cover, and the cover 4 and the connector 1 are integrated. In addition, at the same time, the terminal 8, the lead wire 2 and the sensor 3 are buried into the filler 5. A sensor 10 which is formed in this manner can adjust its thermal time constant easily by changing the composition of the filler 5. In addition, since the connector 1 whose size is different, which is of an arbitrary kind and which is available on the market can be replaced and used, the costs of a connector- integrated sensor can be reduced sharply.

Title: Power shift transmission in tractor
Inventor: HIDA MAMORU
IPC: F16H59/68
Filed: 1989-08-01
Abstract: PURPOSE:To reduce shift shock based on the speed change difference among the respective speed change stages of an auxiliary speed change part by lowering the maximum value of the voltage for controlling a solenoid proportional control valve as the shift-up of an auxiliary speed change part is performed, thus setting the maximum value of oil pressure acting upon the hydraulic clutch of a main speed change part low. CONSTITUTION:When speed change to the fourth ahead gear speed is performed, a hydraulic clutch CM is engaged to change an auxiliary speed change part 3 to the medium speed as well as the voltage based on a control means rises slowly in comparison to the voltage rise at the time of the auxiliary speed change part 3 being at low speed, and oil pressure controlled by a solenoid proportional control valve S1 on the basis of the voltage rises at the slower pressure-up speed compared to the case of low speed. A hydraulic clutch C1 is then engaged by the oil pressure so as to change a main speed change part 2 to the first gear speed. Accordingly, the clutch C1 of the main speed change part 2 is engaged even more slowly accompanied by the shift-up of the auxiliary speed change part 3, thus reducing shift shock caused by the speed change ratio difference among the respective speed change stages of the auxiliary speed change part 3.

When MgO is less than 10%, a working temp. width becomes narrow and the chemical durability of a glass matrix phase is not improved, and when MgO is more than 30%, other crystalline phase is precipitated and desired strength is difficult to obtain.  When TiO2, is less than 7%, melt property becomes worse and also crystal growth is hardly caused, and when TiO2 is more than 12%, crystallization is rapidly accelerated, and the control of crystallization state becomes difficult, and fine and homogeneous crystalline structure is not obtained.
