Title: Vehicle detection device
Inventor: OGAKI TATSUO
IPC: G08G1/04
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To provide a device whose installation construction is easy, which can easily detect the number of wheels and can deal with a high speed vehicle by scanning optical beams to the wheels of the passing vehicle, and detecting the width of the wheels, the number of wheels of respective axles, the number of axles and an interval between the wheels without contact from reflected light. SOLUTION: The optical beams are scanned within a prescribed angle range in parallel to a road and the wheel parts of the passing vehicle are irradiated. In the device, a scanning-type distance measuring optical sensor (laser sensor) 11 irradiates an object with the laser beams and obtains transmission time when the optical beams are reflected and are returned. Data equivalent to transmission time to the object, namely, the distance is outputted to a vehicle detection part 12 as a digital voltage signal. The vehicle detection part 12 measures the width of the wheels, the number of wheels, the number of axles, the interval between the wheels and the wheels based on the distance. A measured result is sent to a host device 13 such as a control panel in a tollgate booth and it is used as data for discriminating a car type, for example.

Title: Manufacture of capacitor for highly integrated semiconductor memory device
Inventor: RIYOU GENSEKI
IPC: H01L27/04
Filed: 1992-12-28
Abstract: PURPOSE: To eliminate the limitation on a width of separating film between storage electrodes due to optical resolution by utilizing a spacer, where a storage electrode is formed in a self-aligned manner for adjoining the thickness of the spacer. CONSTITUTION: A semiconductor substrate 10, where the second material layer 52 is formed is etched anisotropically, for example RIE, to form a spacer 52a of second material on the sidewall of the first material pattern 50. Here, since the spacer 52a is formed in self-alignment method, its thickness is easily minimized, while a contact is kept. The thickness of the spacer decides an interval between the storage electrodes. Since the device is not dependent on optical resolution as in conventional devices, the limit in optical resolution does not limit the interval between storage electrodes.

Title: Method and system for recording digital signal in storage element
Inventor: HAATAJA TERO
IPC: H04W88/02
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To provide a method by which audio signals of two or more can be recorded in a compressed type and a system performing the method. SOLUTION: Each sample of audio signals is recorded only when a voice is detected in the audio signals (step 115). When a voice is detected in samples of audio signals of two or more, memory capacity required for recording is economized by coupling samples of these audio signals (step 110). When a voice is not detected in an audio signal, the signal is not recorded. As coupling of signals, that is, mixing is performed only when a voice is detected in samples of audio signals of two or more, required average calculating capability and power consumption are reduced.
