Filed: 1998-06-25
Abstract: PROBLEM TO BE SOLVED: To allow a failure diagnosis even before a travel start by stopping the feed of output inhibiting signals after feeding diagnostic signals, then receiving response signals to the diagnostic signals from electronic circuit units via a communication bus. SOLUTION: Output inhibiting signals for inhibiting the output signals from first through fourth control units 1-4 to a communication bus 6 are outputted, then diagnostic signals are fed in sequence to the first through fourth control units 1-4 respectively. Response signals to the diagnostic signals fed to the first through fourth control units 1-4 are read from the first through fourth control units 1-4 via the communication bus 6. Whether the read diagnostic result contains the signal indicating a failure or not is judged, and the judged result is fed to a display unit 23 and displayed. A user such as a driver can judge the presence or absence of a failure by seeing the display or by directly seeing the lighting of various lamps.

Title: Manufacture of stone revetted precast concrete plate
Inventor: ORIMO HIROBUMI
IPC: B28B1/16
Filed: 1987-07-21
Abstract: PURPOSE:To protect stone material from the occurrence of tensile stress and to prevent cracking by a method in which stone material is arranged on the bed for placing a precast concrete plate, and while said stone material is cooled, concrete is placed on the upper surface of said stone material and is integrally combined with the stone material. CONSTITUTION:Stone material 3 is arranged on the bed 1 for placing a precast concrete plate through the cooling device 2 constructed so that e.g. liquid nitrogen is sprayed thereonto in gas state, whereby the stone material is cooled by the cooling device 2 and is shrunk. In this state, the concrete 4 is placed on the stone material 3 and is integrally combined with the stone material 3. Thus a stone revetted precast concrete plate is produced. Accordingly, when the stone material 3 is restored to room temperature, it tends to expand, but the stone material 3 is constrained by the concrete 4 integrally laid on the upper surface of said stone material 3, whereby compression stress is introduced in the stone material 3 as prestress. By such method, said stone material 3 is protected from the occurrence of tensile stress, and the occurrence of cracking is prevented.

Title: Developing method
Inventor: YAMAMOTO YOKO
IPC: G03G15/06
Filed: 1987-07-21
Abstract: PURPOSE:To repeatedly perform superior developing, by arranging a toner spraying regulation member having a specific slit so as to arrange the center of the slit at the minimum cavity position between a developing sleeve and a latent image supporting body, and performing developing by spraying a toner on the developing sleeve to the latent image supporting body via the slit. CONSTITUTION:A conductive toner spraying regulation member having a slit whose width (mm) (w) satisfies formula I is arranged so that the slit can be located at the minimum cavity position between the developing sleeve and the latent image supporting body, and developing is performed by spraying the toner on the developing sleeve to the latent image supporting body via the slit. In other words, since a toner spraying area where electric field strength in a vibrating electric field is relatively large is formed by the toner spraying regulation member, it is possible to prevent a toner particle of large particle diameter from being sprayed to the latent image area in an area where the electric field strength in the vibrating electric field is small at the upstream side than the minimum cavity position. In such a way, it is possible to perform the superior developing repeatedly for several times.

Abstract: PURPOSE:To stably record a signal in the same tape pattern as the time of controlling by means of an input signal by providing a selecting means to make the timing of the synchronizing signal of an external reference signal and a necessary signal among the video signals of plural modes into a constant relation. CONSTITUTION:At the time of reproducing, a drum servo compares a signal to indicate the rotation phase of a head cylinder 45 detected by a pulse detector (PG) 44 with the phase of a reference phase signal 46 and is controlled by controlling the rotation of a cylinder motor so that the phase of the video signal reproduced from heads 7 and 8 and the reference signal 46 coincides.

Thus, at the time of dubbing, a reproducing device and a recording time can be controlled by an external reference signal and recorded against the output signal of any mode in a regular recording pattern, and a stable dubbing can be executed.

Abstract: PURPOSE:To generate stable demodulating clocks by holding the oscillated frequency of an oscillating means, which oscillates a frequency in accordance with the level of a control input, as it is when a drop-out detection signal detected from an RF signal read from a recording medium is generated. CONSTITUTION:The RF signal read by a pickup 1 is supplied to a video detector 5, a 1H delay circuit 6, and a drop-out detecting circuit 9 through an HPF2.
