Title: Reflecting surface and its formation
Inventor: KARASAWA TAKESHI
IPC: G02B5/02
Filed: 1998-12-02
Abstract: PROBLEM TO BE SOLVED: To provide a reflecting plate to realize a natural appearance as much as possible and a bright display by forming thin slopes and grooves on a substrate in such a manner that the thin slope makes a specified angle from the substrate surface and that the bottom of the groove has a flat part. SOLUTION: For this reflecting plate, microgrooves 2 are formed on the surface of a substrate 1. The angle 3 between the slope of the groove 2 and the surface is same all over the substrate. When the reflection surface is flat, the distribution of reflection intensity is uniform and wide, while if the reflecting surface has a rugged pattern, it shows directional distribution of the reflection intensity. Since reflection of light on the flat face gives a constant incident angle and a constant reflection angle all over the face, no difference is produced between the distribution of incident light and distribution of reflection light. When a reflection face has special scattering property, light is reflected and condensed to a specified area so that the limited area is brighter compared to the reflection by a flat face.  Moreover, a glittering appearance like a mirror is decreased and an appearance with more natural brightness is obtd.

Title: Uninterruptible communication processing unit disconnection system
Inventor: AZUMA TOSHIHIRO
IPC: H04L69/40
Filed: 1991-12-25
Abstract: PURPOSE:To attain the operation of uninterruptible and non-stop state even when a communication data processing unit is faulty by discriminating whether plural communication data subject to distribution processing are normal or abnormal with a comparison selection section and applying signal multiplex processing to data so that the output are one of data outputted from a communication data processing unit. CONSTITUTION:Input data are fed to a signal distribution section 1 and are distributed, e.g. two data by a signal distribution circuit 10 and its output is fed to synchronization protection circuits 11a, 11b to discriminate the propriety of the distributed data depending on the presence of synchronization establishment. Data of the circuits 11a, 11b subject to synchronization establishment are inputted to communication data processing units 2-1, 2-2, in which the data are converted into two parallel data, which are sent to a comparison selection section 3. The selection section 3 writes a phase difference caused due to a difference from the length of the transmission paths to phase adjustment memories 30a, 30b and are read simultaneously to eliminate the phase difference. Thus, even when any of the units 2-1, 2-2 is faulty, no effect is caused on the processing and which of the units is faulty is discriminated.

Title: Start controller
Inventor: TAKAGI NOBORU
IPC: H02P1/54
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To lock the start adequately in response to a permitted voltage value for each induction motor and a circuit voltage value during the start of the induction motor by locking the closing of a power source switch if the circuit voltage value is lower than the permissible start value of the induction motor. SOLUTION: A permissible start voltage of each induction motor calculated in advance by the impedance or the like of a transformer is set to an induction motor permissible start voltage data file 13 by data input key board 15. And if there is a closing command for a certain induction motor power source switch 4, a circuit voltage value at that time and permissible start voltage value of that induction motor are compared to each other by a computing element 16; if the circuit voltage value is lower, then an excessive voltage drop due to start current is prevented by locking the start permit signal 18. By doing this, the start of induction motor can be adequately operated and controlled for each induction motor by removing previous extreme restriction on the start.

Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To enable prevention of electrode short circuits between leg parts even in the case that high-density electrode arrangement is required, by constituting at least one protruded part between the leg parts of a piezoelectric vibrator, and ensuring electrode isolation between the leg parts. SOLUTION: An energizing electrode 5 is formed at a leg part 2 of a piezoelectric vibrator 1 constituting a piezoelectric vibrator-type acceleration sensor, and a detecting electrode 6 is formed at the other leg part 2 by photolithography. At least one protruded part 3 is provided approximately at the midpoint between the leg parts 2. A photoresist can be scarcely exposed in a Y-plane in the process of photolithography, and a deposition of a metal electrode film is left between the leg parts 2. However, as it is possible to separate the deposition of a continuous metal electrode film at wall surfaces 4 by providing the protruded part 3, it is possible to reduce electrode short circuits between the leg parts 2. The height of the protruded part 3 is necessarily at least 10 μm or more, and the wall surfaces 4 may be formed in parallel or be in the shape of a wedge. It is possible to achieve similar effects in the case that the leg part constitution of the piezoelectric vibrator 1 is in the shape of a letter H.

Title: Automatic coating device
Inventor: WAKAMIYA KOJI
IPC: B05B13/04
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To dispense with a cleaning step and thereby improve productivity. SOLUTION: An object to be coated 3 finding its way through a carrying-in path 1 is sequentially upheld by plural supports 5 which rotate around a horizontal shaft, and then is coated by atomizing a paint in the process of a rotary transfer of the object 3 around the shaft, and finally is sent out to a carrying-out path 2. Consequently, a paint mist does not stick to both carrying-in path 1 and carrying-out path 2 and therefore, does not soil the object 3. In addition, a conventional step to clean the paint mist which is a contaminant sticking to the carrying-in path 1 and the carrying-out path 2 is no longer necessary, and this fact contributes to the enhancement of productivity.  Further, the paint applied to the object 3 is hardly transferred to the carrying-out path 2, as the object 3 is dried in such a state that it is upheld by the supports 5 which rotate the object 3 around the shaft after spray coating and then is transferred to the carrying-out path 2. Thus a good coating film is formed and the paint does not stick to the carrying-out path 2.

Abstract: PURPOSE:To provide an infrared sensor whose absorption efficiency of infrared rays is higher than that in conventional cases. CONSTITUTION:The figure shows the cross section of an infrared sensor provided with a temperature-sensitive film of a wedge-shaped structure as one example of this invention. A hollow is formed in an Si substrate 7, a temperature-sensitive film 5 which is supported by a support layer 4 is formed to be of a V-wedge-shaped structure, and a thermosensitive element 6 is formed at its bottom part. An infrared absorption film 1 is formed on the surface of the film 5 via an insulaitng layer 2. Infrared rays which are incident as to be deviated from the center are absorbed considerably by the absorption film 1, but they are incident again on other parts in the sensitive film so as to be absorbed there again. The inclination of a wedge shape is set at an angle at which the rays are reflected three times, and their absorption efficiency is enhanced remarkably.
