Title: Semiconductor photodetector
Inventor: MIKAWA TAKASHI
IPC: H01L31/10
Filed: 1987-05-19
Abstract: PURPOSE:To reduce noise upon place fluctuation of ionization probability by forming an APD magnifying layer by alternately laminating layers each having 500Angstrom  or more of thickness not becoming a superlattice structure and small carrier ionization threshold value energy (small band gap), and layers each having large energy, and limiting ionization layers in a high electric field range to plurality. CONSTITUTION:A magnifying region formed by alternately laminating n-type GaAs layers 2 as an optical absorption layer, N-type AlxGa1-xSb (x=0.3) layers 3A-3C (500Angstrom  and beyond in thickness), and n-type AlxGa1-xSb (x=0.06) layers 4A-1C (500Angstrom and beyond in thickness) and an n-type AlxGa1-xSb (x>=0.3) layer 5 are sequentially grown. Then, Zn of Cd is diffused as a P-type impurity from the surface of the layer 5 to form a P<+> type region 6. Thus, ionizing positions of the APD magnifying region can be limited to several positions to reduce noise upon place fluctuation of ionization probability.

Title: Wafer positioning apparatus
Inventor: HASHIMOTO NORIYOSHI
IPC: H01L21/67
Filed: 1985-06-05
Abstract: PURPOSE:To detect only a notch without contact, by reading the shape of the periphery of a wafer by using a light emitting part and a light receiving part, and detecting the notch based on the width of the detected signal. CONSTITUTION:The detected signal in correspondence with the outer shape of a wafer is obtained by the light emitting part and the light receiving part of a detecting circuit 10. The signal is differentiated in a differential circuit 13. The result is compared with the first threshold value from a threshold value generating circuit 15 in a comparing circuit 14. Thus, a time point, where the detected signal is largely changed, is obtained. Both a notch and an orientation flat are thus detected. The detected signal is compared in a comparing circuit 17. The time, when the detected signal exceeds a second threshold value, is counted by a counter 18. The width of the detected signal, which exceeds the second threshold value, is obtained. The width of the detected signal, which exceeds the second threshold value due the change in level caused by the notch, is smaller than the width of the detected signal exceeding said value due to the change in level caused by the orientation flat.

Title: Three-phase shunt reactor device of variable capacitance type
Inventor: HARUMOTO YASUMASA
IPC: H01F29/00
Filed: 1982-07-13
Abstract: PURPOSE:To realize a miniaturization of the titled device, by a method wherein three shunt reactors of variable capacitance type are arranged in parallel, each reactor comprising an intermediate core with a gap disposed between a main winding and a secondary winding, and the main windings are connected to three-phase lines respectively. CONSTITUTION:If switches are opened, main flux is generated in distribution in main cores 1A-1C and intermediate cores 6A-6C. In three-phase lines, vector sum of main flux distributed in the main cores 1A-1C and intermediate cores 6A-6C becomes zero. Both ends of the main cores 1A-1C are magnetically connected by a yoke core 10, thereby each main core and intermediate core have partial flux circulating therein so as to constitute prescribed main flux and vector sum of the partial flux becomes zero. If the switches are closed and secondary windings are shortcircuited, flux is produced in intermediate cores. Since the intermediate cores are connected by a yoke core 11, flux in each intermediate core is circulated and vector sum thereof is zero. Irrespective of whether the switches are opened or closed, flux produced in each core is circulated even if the core is not magnetically shortcircuited by a yoke core 8. Since the yoke core 8 needs not be used, the device is produced in light weight.

Title: Optical axis adjusting method for semiconductor laser optical fiber
Inventor: YOJIMA MASAYUKI
IPC: G02B6/42
Filed: 1989-05-15
Abstract: PURPOSE:To reduce or release the frictional resistance between holder contact faces of first and second holders by minutely oscillating one of these holders in the direction of the optical axis at the time of aligning them in a plane perpendicular to optical axes. CONSTITUTION:The end face perpendicular to the optical axis of a first holder 2 which holds a semiconductor laser and has the end face perpendicular to the optical axis and that of a second holder 3 which holds an optical fiber and has the end face perpendicular to the optical axis are closely brought into contact with each other and are pressed to each other. One of first and second holders 2 and 3 is minutely oscillated in the direction of the optical axis to align first and second holders between end faces perpendicular to the optical axes so that the laser light output of the semiconductor laser transmitted through the optical fiber is maximum. Thus, minute oscillation does not affect the optical axis alignment because the positional deviation allowable range in the direction of the optical axis is wider than that in the direction perpendicular to the optical axis, and the frictional resistance between contact faces of holders 2 and 3 is reduced or released.

Abstract: PURPOSE:To prevent the bursting of a container packed with a food in heat sterilizing the container packed with the food by irradiating with microwaves, by filling a particulate or granular material consisting of a material having a small dielectric loss in a gap between the container packed with the food and the containing vessel. CONSTITUTION:A food 2 is packed in a container 1 consisting of a material having a small dielectric loss with microwaves and sealed. The container 1 packed with the food 2 is then introduced into a containing vessel 3, consisting of a material having a small dielectric loss with microwaves, and provided with innumerable micropores 5 on the wall thereof. A particulate or granular material 7 consisting of a material having a small dielectric loss, and incapable of passing the micropores 5 is then filled in a gap part between the inner wall of the containing vessel 3 and the container 1 packed with the food 2. The containing vessel 3 is then covered with a lid, and irradiated with microwaves from the outside  of the containing vessel 3 to sterilize the container 1 packed with the food 2 under heating. Thus, the bursting of the container 1 packed with food 2 due to the increase in the internal pressure thereof is prevented.

Abstract: PROBLEM TO BE SOLVED: To make compatibly the convenience in mounting and the safety in carrying around, by installing a Hook-and-Loop fastener so that a belt sewn in such a way as laid on one side and wound on the other side is folded into two segments. SOLUTION: The Hook-and-Loop fastener 4 is laid on one side of a belt 2 made form cloth, etc., in approx. half overlapping followed by sewing or fusion attachment and another Hook-and-Loop fastener 3 is wound on the other side followed by sewing or fusion attachment and the obtained object is installed in a portable case 1 for accommodation of a camera, etc. Otherwise, the belt 2 furnished on one side with the Hook-and-Loop fastener 3 and another Hook- and-Loop fastener 4 may be installed in the case 1 separately. The side of belt 2 on which the Hook-and-Loop fastener 3 is installed, is threaded to a belt for trousers, etc., and the inside of the fastener 3 is adhered to the fastener 4, and a surplus portion of the fastener 4 is wound on the outside of the fastener 3 and adhered.  Even if a force to set off the belt threader from the case acts when the case is fitted and the body is moved, the part where the fastener 4 is wound on the other 3 will never be set off, so that there is no risk that one drops the case. The belt threader can easily be mounted and removed.
