Title: Disc brake having parking drum brake
Inventor: HASHIMOTO NOBUO
IPC: F16D65/02
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To secure rigidity, stabilize braking torque, reduce weight and a manufacturing cost by fixing an anchor to a back plate at plural positions spaced from each other, and connecting the anchor to a support bracket across the back plate. SOLUTION: A brake pad is brought into press-contact with a brake disc 22 by means of a brake pedal, for appling braking force. Braking torque applied from the brake disc 22 to a brake caliper is transmitted to a back plate 9 through a support bracket 24. Rigidity of the back plate 9 is improved by sandwiching an upper anchor 14 and the support bracket 24. In addition, the braking torque applied to one end 24a of the support bracket 24 is transmitted to the upper anchor 14 through a bolt 30, and to the back plate 9 through a bilaterally pair of rivets 27. That is, it is scattered to plural positions. It is thus possible to suppress deformation of the back plate 9 caused by braking torque, and stabilize operation without especially thicken the back plate 9.

Title: Monitor device for controller
Inventor: SUZUKI MAKOTO
IPC: H02M7/155
Filed: 1981-05-19
Abstract: PURPOSE:To monitor all defective phenomena to improve the reliability, by monitoring the phase sequence of ignition signals from respective controllers as well as the coincidence among ignition signals of corresponding phases of all controllers. CONSTITUTION:When regular ignition signals are inputted to terminals U-Z and a monitor starting signal is inputted to a terminal ST, pulses having a constant width of time are outputted to lines Fu-Fz through an OR circuit 14, an AND circuit 15, and a flip-flop (FF)16. When an on-delay timer 17 is placed after the FF16 and the time of this timer 17 is set to a time longer than the pulse width, outputs of timers 17U-17Z are not issued, and therefore, no output is issued to a terminal K1, and normality is discriminated. If, for example, an ignition signal W is not issued, an FF16W is not set, and an FF16V is not reset, and the signal is outputted to the line FV continuously, and the output signal is issued to the terminal K1. A monitor device is constituted with a monitor circuit for the phase sequence, which monitors the phase sequence in this manner, and a circuit which monitors the coincidence among ignition signals corresponding to the phase sequence.

Title: Video coding device
Inventor: MORII TOSHIYUKI
IPC: G10L19/12
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a voice coding device obtain a satisfactory synthetic sound by a small computational complexity in the efficient compression coding of voice information. SOLUTION: Plural pairs respectively having three values of 'the number of shifts' 'a position where pulses are to be raised' and 'the gain of pulses' are stored in a sound code book 14 and the sound source signal of a certain number is formed merely by such a processing that pulses having the magnitude of 'the gain of pulses' are raised at 'the position where pulses are to be raised' by shifting the sound signal of a preceding number by 'the number of shifts' allowing the sound source signal consisting of plural pulses to be generated in a sound source generating part 110 based on the three values stored in the sound source code book 14. Consequently, since it is sufficient that only three values are stored in the book in one number, the capacity of a ROM needed for the code book 14 is extremely small.

Title: Manufacture of compound semiconductor
Inventor: MIHASHI HIROSHI
IPC: H01L21/205
Filed: 1988-03-31
Abstract: PURPOSE:To facilitate control of physical properties of a semiconductor at an atomic order level, by applying different intensities of light in the course of the growing process. CONSTITUTION:When light is introduced into a growth reaction tube for the metal organic chemical vapor deposition process (MOCVD), amount of photochemical reaction of a material or between the material and crystal surfaces is varied according to intensity of the light. Further, amount of the photochemical reaction is varied also according to types of raw materials. Using these facts, values of physical properties such as composition of the crystals to be grown and concentration of carrier are controlled by varying intensity of light. When vapor growth is performed while the surface of a compound semiconductor or a region near there is irradiated with light, the intensity of light can be varied so that a coefficient of decomposition of the raw materials or amount of reaction can be varied simultaneously therewith. Accordingly, properties of the semiconductor being deposited can be changed in an instant. In this manner, superlattices requiring steep hetero interfaces or very high speed transistors, which have been difficult to produce by the conventional vapor growth process such as MOCVD, can be produced very easily.

The aforementioned heating is performed concretely at 50 deg.C or more, pref., at 70-100 deg.C. By this method, the catalyst having the noble metal colloidal particles fixed thereto can be obtained more simply as compared with a conventional method with good reproducibility.

Title: Electric power recovering circuit for plasma display panel
Inventor: MATSUSHITA MASAHARU
IPC: G09G3/296
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To effectively absorb a spike voltage generated in a power recovering coil and to transiently prevent a high voltage and a high frequency current from generating by connecting a RC circuit composed of a capacitor and a resistor in parallel to the power recovering coil for outputting a voltage from an electric power recovering capacitor. SOLUTION: When a current is flowing through an electric power recovering coil L and a switch S3 or a switch S4 is turned off, the current flowing through the power recovering coil L becomes instantaneously OA. Consequently, the changing amount of the current flowing through the power recovering coil L is very large. Then, a CR circuit 5 composed of the direct connection of a capacitor C1 and a resistor R1 is connected to the power recovering coil L in parallel. The CR circuit 5 is a circuit for connecting both ends of the power recovering coil L, absorbs an AC component generated on the both ends of the power recovering coil L and effectively absorbs a spike voltage at the time of turning off the switches S3, S4. Consequently, the deterioration of a withstand voltage in an EMI and the circuit parts is effectively prevented.
