Title: Pressed bumper reinforcement having substantially b- shaped closed section, and its manufacture
Inventor: ANDO SHOJI
IPC: B60R19/04
Filed: 1999-08-05
Abstract: PROBLEM TO BE SOLVED: To provide a bumper reinforcement light in weight and high in safety by pressing a high tensile steel plate into a substantially B-shaped closed section, and permanently welding a joining part. SOLUTION: A high tensile steel plate is pressed into a U-shaped section. Then, a hat shape is pressed in a center of the section. Next, a riser is pressed on both ends of the section. In addition, a diagonal riser of the substantially angle shape is pressed on both sides of the section. Then, both sides of the section are pressed. Finally, a joining part is permanently welded. A bumper reinforcement 1 having substantially B-shaped closed section provided with a forward surface 61 and a rear surface 65 can be obtained. Since the bumper reinforcement 1 is large in section modulus and excellent in strength of each part, a thinner high tensile steel plate can be used. The bumper reinforcement to meet the request for weight reduction can be obtained while satisfying the functions of the necessary strength, the energy absorption during the collision, etc.

Abstract: PURPOSE:To prevent a deterioration of battery efficiency and to charge a specific amount securely in a simple structure even at a low temperature by adding a bypass pipe line and winding a part of the pipe line to a pump motor to utilize the operation heat of the motor effectively so as to heat the electrolyte. CONSTITUTION:When the temperature of the electrolyte 18 is lowered in a cold time in winter or the like, a 4-way valve 52 is set in the second condition, the electrolyte 18 including a complex compound 32 delivered from a positive electrode side electrolyte 22 passes through the route a-b-c-d, and it is fed to a positive electrode side reaction jar 14. That is, after the electrolyte 18a is delivered from the positive electrode side electrolyte storage tank 24, it is put in a bypass pipe line 50 and led to a spiral 50a wound around a pump motor 31. As a result, after the positive electrode side electrolyte 18a flowing in the spiral 5a in the bypass pipe line 50 is heated by the operation heat, it passes through the 4-way valve 52 and input to the positive electrode side reaction jar 14 from a positive electrode side electrolyte feeding pipe 28. Consequently, a specific amount of charging can be carried out securely even at a low temperature.

Title: Memory device
Inventor: SATO TAKASHI
IPC: H01L27/115
Filed: 1988-09-06
Abstract: PURPOSE:To make a memory device large in memory capacity by a method wherein the presence or the absence of data is memorized taking advantage of the change of an electric capacity due to the bend of a semiconductor layer band induced by the trapped charges. CONSTITUTION:A voltage is applied between electrodes 3 and 7, and charges are discharged from a semiconductor layer 4 or the electrode 7, which are trapped by a trap level subsisting near the interface of an insulating layer 4 inside an insulating layer 6. The bend of a semiconductor layer 4 band is made to take place through the trapped charges, whereby the semiconductor layer changes in electrical capacity to cause the electric capacity change between the electrodes 3 and 7. The presence or the absence of date can be memorized using the change of an electrical capacity. Even after a voltage supply has been turned off, the trapped charges are retained as a non-volatile memory, so that this structure can serve as a non-volatile memory device. Thereby, a large capacity device can be obtained at a low bit cost.

Title: Non-reversible circuit
Inventor: HARA SHINJI
IPC: H01P1/32
Filed: 1988-09-06
Abstract: PURPOSE:To form a non-reversible circuit suitable for a semiconductor monolithic micro wave IC by connecting a load to the connection line of an antiphase distribution circuit and an in-phase synthesis circuit on one side, and taking impedance matching for the line on the other side by the in-phase synthesis circuit. CONSTITUTION:A signal inputted from a terminal 1 to the antiphase distribution circuit 4 goes to two output with anti-phases mutually, and goes to two input to the terminals IN, IN of the in-phase synthesis circuit 11, and also, the output is issued from a terminal 2, and remaining output is absorbed by the load 12. Here, the circuit 11 realizes the impedance matching of the terminal 2 by using a 1/4-wave line, etc. Also, the signals inputted to the IN 1 and IN 2 of the circuit 11 become the same level with the antiphases setting an external circuit connected to the terminal 2 and the load 12 at the same impedance, and no output is issued to a terminal 3, and terminal input is outputted only to the terminal 2. Next, terminal 2 input is not outputted to the terminal 1 since a circuit 4 is the one with unidirectionality, and is outputted only to the terminal 3. Furthermore, the input of the terminal is outputted only to the terminal 2 since the circuit is of the unidirectionality.

IPC: H02K7/102
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To obtain a device in which a center deviation is not generated between an encoder and a motor shaft, by a method wherein a connecting hole is recessed and formed in the encoder and an encoder main shaft which is installed so as to protrude from a braking-gap adjusting plate is fitted to, inserted into, and connected directly to, the connecting hole. SOLUTION: An input shaft 11 which is fitted to, inserted into, and connected directly to, connecting hole 10 which is recessed and formed in a rotary encoder E is installed coaxially with a motor shaft D in a boss part at a braking-gap adjusting plate 4. Then, the input shaft 11 is connected directly to the encoder E by a locking pin 12 in the radial direction. An encoder-mounting leaf spring 13 is attached to an encoder holding plate E' by a bolt B3, and the mounting leaf spring 13 is fixed to a motor case. Thereby, the distance between the encoder E and the motor shaft D is shortened, and the encoder E can be built in a fan cover in which a braking-plate cooling fan is housed.  The encodr part E does not protrude form the fan cover, it is hardly subjected to the influence of an external force, and there is no fear that a center deviation due to an external force is generated between the motor shaft D and the encoder E.

Title: Vapor growth device
Inventor: MARUYAMA KENJI
IPC: H01L21/365
Filed: 1985-10-08
Abstract: PURPOSE:To manufacture a multilayer epitaxial layer having high film-thickness precision and a uniform crystalline composition with high yield by forming a device by a region, in which a gaseous element having a large diffusion coefficient is diffused, and a region, in which elements except the gaseous element where grown in an epitaxial manner, and moving a substrate into both regions by turning a control rod. CONSTITUTION:In a vapor growth device, a region in which there is a reaction gas is divided into two by a partition wall 14, and a crystal substrage 1 to which epitaxial growth is conducted can be shifted in the two regions by rotating a control rod 10. The crystal substrate 1 is held and CdTe epitaxial growth is performed. When a CdTe layer 2 in approximately 0.05mum is grown, the control rod 10 is half-turned, and the crystal substrate 1 is transferred into Hg vapor. Consequently, Hg atoms precipitate on the CdTe layer 2, and a solid-phase diffusion instantaneously progresses at the temperature of precipitation and Hg atoms change into a HgCdTe layer 3 with time. As a result, the control rod 10 is half-turned further at a step when the solid-phase diffusion progress up to half the epitaxial-grown CdTe layer 2, and said operation is repeated. Accordingly, the accuracy of film thickness is improved, and a homogeneous composition is acquired continuously.
