Title: Cam lock locking mechanism
Inventor: FURETSUDEI GEIE
IPC: B64G1/64
Filed: 1990-09-12
Abstract: PURPOSE: To simplify operation so as to reduce energy required to lock and unlock by forming a contact surface of a cam to have a logarithmic spiral profile while forming a holding face to be flat, and providing resilient means for rotating the cam, and a means for rotating a hub with a stub off the center of a rotating shaft. CONSTITUTION: When a member 11 is oscillated around a fixed shaft 17 until its front face 39 comes in contact with a front end face 39 of a cam 1, the cam 1 is pushed back against a spring 29 by the front face 39, and a contact surface 3, having a logarithmic spiral profile, of the cam 1 is held to a plane 5 to be the slit bottom part of the member 11 to lock members 10, 11. In the case of unlocking the members 10, 11 from this optimum lock position, a handle 21 has only to be rotated counterclockwise. With this rotation, the contact surface 3 of the cam 1 is first lifted from a holding face 5 for eccentric mechanisms 20, 21, and the cam 1 is moved away against the spring 29 by a stub 26 to unlock.

Title: Motor drive
Inventor: HORI NORIHIKO
IPC: H02P1/22
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To protect relay contacts from overcurrent a motor being driven is inverted. SOLUTION: When a motor 33 is being forward driven with polarity changing signals SA and SB at HIGH level and LOW level, respectively, the capacitor 40 in a drive limiting circuit 34 is charged with the voltage E of a battery 23 and a transistor 38 is on. When the polarity changing signals SA and SB are switched to the LOW level and HIGH level, respectively, the transistor 38 is kept on while the capacitor 40 is discharged. Thus, the timing with which a transistor 29 is turned on is delayed, and both the terminals of the motor 33 are kept short-circuited to each other during the discharge time the capacitor 40. Since a voltage for inverse drive is, as a result applied to the motor 33 after deceleration or stop, the production of overcurrent arising from motor induced voltage is suppressed.

Abstract: PURPOSE:To increase the length of a single crystal growth layer through lateral solid-phase epitaxy by forming an implanting region for neutral ions, a dosage thereof is increased in succession in one direction, on a semiconductor layer shaped onto a substrate and thermally treating the implanting region. CONSTITUTION:An SiO2 layer 2 is formed onto an silicon substrate 1, and a crystal silicon thin-film 3 is brought in to an amorphous state. A mask layer 8 is applied and shaped selectively extending over a predetermined distance d2 from the end section of an opening 6 on the silicon thin-film 3, and silicon ions Si<+>9 in a high dosage are implanted into a region in which the mask layer 8 is not formed. Consequently, a region 10 in a low dosage and a region 11 in the high dosage are shaped to the silicon thin-film 3. A single crystal is grown to the region 11 in the high dosage from the region 10 in the low dosage in the silicon thin-film 3, using the substrate 1 as a seed through heat treatment. Since no random nucleus is generated yet in the region 11 in the high dosage at a time when the region 10 in the low dosage is all turned into the single crystal at that time, single crystal growth further progresses to the region 11 in the high dosage. Accordingly, a single crystal growth layer 3A having a long distance D of 10mum is acquired.

Abstract: PURPOSE:To increase safety with improved accuracy of pressure control in furnaces by installing an automatic control means controlling automatically a common final control element on the basis of the operation amount set by an operation amount set means presetting the operation amount of the common final control element. CONSTITUTION:When the differential pressures of dampers 51, 52 installed at respective ethylene cracking furnaces 11, 12 deviate from the controlable range of the pressure in the furnaces, the changes in the differential pressure are detected by the control deviation En1, En2 and the opening of a common damper 9 is automatically adjusted by the preset adjustable amount with a preset period in the direction that the differential pressures return back to a controllable range in the furnace inside pressure. Accordingly, there is no such danger that pressure control for the furnace inside is impossible and the furnaces are brought in unstable combustion condition. As the adjustable amount and frequency for the opening of the damper 9 can be freely set, proper values are selected and bad influence for the dampers 51, 52 due to quick change in the opening of the damper 9 can be prevented. The stable automatic control of the damper 9 corresponding to the change in the differential pressure of the dampers 51, 52 is achieved and the accuracy in pressure control for the furnace inside is improved and safety is increased.

Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor element which is provided with a buffer layer of good interface characteristics and film characteristics for preventing diffusion of a metal element from a ferroelectrics film to a silicon substrate, by providing an oxynitride layer as a buffer layer between the ferroelectrics film and the silicon substrate. SOLUTION: An SiON film 3 is formed as a buffer layer on a silicon substrate 1, and a ferroelectric film 4 and a gate insulating film 5 are formed into an island-shape on the SiON film 3. Since the SiON film is tighter in structure than a silicon oxide film, the ability for suppressing the diffusion of a metal element constituting a ferroelectrics is high. By controlling the nitrogen concentration in the film to 10% or below, interface characteristics and in-film fixed charge density which is about the same level as the silicon oxide film are provided. So, by using the SiON film, the metal diffusion from a ferroelectrics is prevented with a film which is thinner than the silicon oxide film while such interface and film characteristics of as almost the same level of the silicon oxide film are provided.

Title: Variable impedance circuit
Inventor: HITOMI JUICHI
IPC: H03H11/12
Filed: 1987-09-25
Abstract: PURPOSE:To prevent a cut-off frequency from dislocating by connecting respectively the source and gate of a second transistor to the gate and source of a first transistor out of an MOS type transistors and holding constantly the voltage between the gate sources of the second transistor with a current source. CONSTITUTION:An input voltage Vin becomes Vin(DC)+Vin(AC). A voltage VGS1 between the gate source of a MOS transistor Q1 becomes VGS1=Vin-VS3. Provided that the VS3 is the soruce voltage of a transistor Q3. Since VGS1=VGS3 is obtained, a voltage VGS3 between the gate sources of a transistor Q3 is controlled by a current IDS between drain sources. VGS1 goes to constant regardless of the AC component of a signal inputted from a terminal 14. For this reason, an impedance RQ1 in the transistor Q1 becomes constant. Consequently, without the distortion of an output signal waveform, a cut-off frequency is not also dislocated.
