Title: Manufacture of semiconductor memory device
Inventor: HIROKI MASANORI
IPC: H01L27/10
Filed: 1984-12-12
Abstract: PURPOSE:To prevent fine holes from being formed larger than the designed value by a method wherein an N-type impurity is kept introduced to the surface part of a semiconductor substrate, which is then etched by isotropic etching; thereafter, fine holes are formed by anisotropic etching. CONSTITUTION:The N-type impurity, e.g. As, is introduced by ion implantation to the surface part of the semiconductor substrate 1 exposed through an aper ture. An aperture 9 is formed by removing an etching mask 8 over the region which is provided with a fine hole. Next, the surface part of the substrate 1 exposed through the aperture 9 is etched by isotropic etching. Since the N-type impurity has been introduced to the surface part of the substrate 1, the above- mentioned isotropic etching gets the etching speed higher in the planar direction than in the depth direction; therefore, the part corresponding to the upper end of a fine hole 20 is formed in tapered form. Then, the fine hole 10 is formed by anisotropically etching the substrate 1 in the depth direction. Anisotropic etching allows scarce advancement of etching in the planar direction.

Title: Remote controller
Inventor: TAKEHANA CHIKAGE
IPC: B60R25/20
Filed: 1996-10-01
Abstract: PROBLEM TO BE SOLVED: To improve operability and burglar preventing performance by setting a remote controller to at least two kinds of conditions, on alert and on standby, and switching a condition for determining key unlocking according to a set mode. SOLUTION: Upon receiving a signal from a remote controller 20, an on- vehicle device 30 determines if the signal is a corresponding normal signal or not, and if it is a normal signal, the device 30 decodes the signal for its instruction. If the signal is a mode switching signal for indicating a mode switching instruction, a mode is switched (a standby mode is switched to an alert mode, and an alert mode is switched to a standby mode). If the signal is an unlocking signal for indicating unlocking of a trunk, a mode is detected and, if the mode is a standby condition, the trunk is unlocked, and if the mode is an alert condition, the trunk is unlocked only when an unlocking signal continues within a range of a specified time (over 30 seconds to below 20 seconds). Once unlocked, the trunk is half-opened. Thus, relocking is prevented until the trunk is closed again by a man.

Title: Analog signal collating device
Inventor: EDOWAADO AASAA BURATSUKAATO
IPC: H04M3/30
Filed: 1984-12-12
Abstract: The present system employs a high speed digital signal processor which is programmed to generate pairs of digitized waveforms, each pair representing a pair of different frequencies in response to coded input signals. Each pair of different digitized waveforms, when converted and combined into an analog signal, represents a «tone pair» as used in major telephone systems. The tone pairs are transmitted through an anti-aliasing filter circuit (27) and therefrom through amplification circuitry (139) to a tone pair decoder (19) of the type used in major telephone systems. At the tone pair decoder the tone pair signals are reconverted into binary signals. The binary signals from the tone pair decoder are transmitted to a data processor (11) in the system under test, whereat they may or may not be further decoded. Ultimately the binary signals are compared with the coded input signals originally sent. In this way, the system which is designed to handle digital signals and which is designed to handle digital to analog conversions, is tested. The test circuit employs components already present in the system, or readily adaptable from the major telephone systems equipment.

Title: Electrode wire for wire electric discharge machining
Inventor: USUI YASUO
IPC: B23H7/08
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To reduce manufacturing costs for an electrode wire and maintenance costs for a discharge machining tool by using an electrode wire having a relatively high tensile strength, made of a stainless steel small in diameter and having small electric conductivity and improving the machining accuracy of an article to be machined without performing surface grinding after discharge machining. SOLUTION: An electrode wire is made of a stainless steel having a tensile strength of 200 to 300kgf/mm<2> and a wire diameter of 0.05 to 0.20mm, its electric conductivity is low being set to 1 to 3% and thus, the tension of a wire is increased three times as high as that of a brass wire during discharge machining and the vibration of the electrode wire caused by explosion during discharging is reduced. Also, since discharging energy is controlled, a discharge gap is reduced and the surface roughness of a machined surface and machining accuracy are greatly improved. Further, since the electric conductivity is small, influence on machining accuracy and surface roughness is small even when the specific resistance of machining liquid is small.  Thus, the management of the specific resistance during an operation is facilitated and maintenance costs including an ion exchange resin or the like are reduced.

Abstract: PURPOSE:To improve the performance of the damping force characteristics in the low speed area by abuting a pressing member on the outer end surfaces of an extension leaf valve and a compression leaf valve, communicating each pressing member with a control rod through the elastic material, and making it possible to move the control rod vertically from the outside. CONSTITUTION:At the time of the extension the oil flowing from an extension port 26a deflects an extension leaf valve 27, and at the time of the compression the oil flowing from a compression port 26b deflects a compression leaf valve 28 so as to generate the damping force respectively. When pressing members 29, 30 for abuting to the extension leaf valve 27 and the compression leaf valve 28 are moved vertically from the outside through control rods 39 and 42, the pressed load by the pressing members 29, 30 and the elastic members 31, 41 is changed, and the rigidity of the extension leaf valve 27 and the compression leaf valve 28 is adjusted in response to the load so as to adjust the damping force. Since a damping force generating mechanism by the orifice characteristics provided in a piston rod is abolished, the damping force in the low speed area of a piston 22 becomes high.
