Title: Valve plunger retaining structure in a booster
Inventor: UYAMA SHINTARO
IPC: B60T13/57
Filed: 1995-12-21
Abstract: A booster e.g. for a brake includes a key member 31 which prevents valve plunger 11 being removed from a valve body. On the rear side of the key member, the valve plunger 11 is slidably guided by a guide portion 6a of the valve body, and the forward end of the guide portion supports the rear face of the key member when the plunger moves rearwardly relative to the valve body. A radial passage 17b, which receives the key member, and axial passages 17a around the guide portion form a variable pressure passage communicating with a variable pressure chamber (5, Fig. 1) of the booster. Elastic members 32 of rubber prevent the key member from coming off the valve body and prevent noises being produced when the key member abuts the inner surface (1) of the booster. <IMAGE>
Patent GB-2299446-A (GB)
Title: Mass spectrometers
Inventor: FRANZEN JOCHEN
IPC: H01J49/40
Filed: 1996-03-27
Abstract: The invention relates to the orthogonal injection of ions into a time-of-flight mass spectrometer, in which the ions preferably originate from ion sources which are located outside of the vacuum system of the mass spectrometer. The ions are introduced, e.g. from an electrospray source, into a multipole rod arrangement 12 with extended pole rods which stretches orthogonally to the flight direction 19 of the ions in the time-of-flight spectrometer, and then outpulsed by means of a rapid change of the electrical field, perpendicular to the rod direction, through the intermediate space between two rods. The multipole arrangement can take the form of an ion storage device by fitting reflectors 10, 14 to the ends. The multipole arrangement can be filled with the aid of another multipole arrangement which takes the form of an ion guide 8. Damping of the ion oscillations with the aid of a collision gas leads to a collection of ions in a very thin thread on the axis of the multipole arrangement, providing the time-of-flight spectrometer with an excellent mass resolving power due to the uniform initial energy and low energy spread of the ions.

Title: Increasing speed of memory IP/OP buffer using post charge logic with different pulse widths for read and write data
Inventor: LEE JAE JIN
IPC: G11C7/22
Filed: 1996-07-01
Abstract: A pulse signal transfer unit employing post charge logic, comprising a buffering circuit for transferring data with a specified logic value through a data transfer line, a PMOS transistor for supplying a voltage from a voltage source to the data transfer line to initialize a signal on the data transfer line, and a feedback loop circuit for applying the signal on the data transfer line to the PMOS transistor for one of the first and second time periods in response to an external write drive signal to control the PMOS transistor, the second time period being longer than the first time period. According to the present invention, in the case of accessing read data with a relatively narrow pulse width and write data with a relatively wide pulse width, the pulse signal transfer unit initializes the read data at a relatively high speed and the write data at a relatively low speed to provide a signal with a wider pulse width. Therefore, the pulse signal transfer unit is capable of preventing the formation of a current path and enhancing the data processing speed.

Title: Device for detecting moving body deviating from course
Inventor: MATSUDA TOMOO
IPC: G05D1/02
Filed: 1996-05-27
Abstract: Traveling paths over an entire traveling area are arbitrarily determined and can be flexibly changed. Traveling paths in the traveling area (20) where a moving body is to travel are arranged beforehand. For example, the marks adjacent to one another vertically and horizontally are rotated by 90{ and the marks adjacent to one another in oblique directions are inclined at the same angle. Therefore, when arbitrary predetermined traveling paths (A, B) in the predetermined traveling area (20) are selected and the moving body travels along the paths (A, B), line segment crossing detectors mounted on the moving body detect crossing all line segments which constitute predetermined passing marks corresponding to the paths (A, B). In this manner, it is possible to detect deviation from the paths (A, B). Also, even if some of more than two line segment crossing detectors cannot detect crossing all the line segments which constitute predetermined passing marks (paths C, D), at least one line segment crossing detector can detect crossing all the line segments which constitute the predetermined passing marks (paths A, B), whereby it is possible to detect deviation from the course.

Title: Recording and reproducing voice memos during a portable telephone call
Inventor: GOH DAE-GUN
IPC: H04M1/72433
Filed: 1999-06-18
Abstract: A portable telephone records a short voice memo during a call and reproduces the recorded short voice memo later. Upon detection of a voice record key input 113 during a call, the portable telephone converts an input voice signal to voice data, stores the voice data, and determines whether a stop key is input. Upon detection of the stop key input, the telephone stops storing the voice data and displays 115 an index number input request message. Upon detection of an index number input in response to the index number input request message, the telephone records the stored voice data in a voice memo table in association with the input index number, and determines whether a voice reproduce key is input. Upon detection of the voice reproduce key input, the telephone displays an index number input request message and determines whether the voice memo table has a voice memo corresponding to an input index number. When the voice memo table has a voice memo corresponding to the input index number, the telephone reproduces the voice memo using a speaker.

The glass fibre (6) may be placed on a first layer (4) of an encapsulating film e.g. acrylic and a second layer (10) of an encapsulating film e.g. acrylic may be provided on the wetting agent (8) to form a sandwich before heating and cyclical loading. The wetting agent may be thermoset. Alternatively a polymer such as polycarbonate may be back injected against the pre-peg (22) in a mould (20) in which the heat from the polymer of the be used to cure the thermoset polymer of the wetting agent.
