Publication number: 20240101093Abstract: A vehicle brake system includes a switching valve switchable between a first state allowing communication between a first fluid pressure generating device and a frictional brake and a second state allowing communication between a second fluid pressure generating device and the frictional brake. The second fluid pressure generating device generates a fluid pressure by moving a piston with an electric actuator, and has a fluid pressure supply port connected to the switching valve and an atmosphere opening port connected to a reservoir tank. When, due to a failure, the switching valve becomes a third state in which the switching valve makes each of the first fluid pressure generating device and the second fluid pressure generating device communicate with the frictional brake, a control device controls the second fluid pressure generating device to close the atmosphere opening port with the piston.Type: ApplicationFiled: September 20, 2023Publication date: March 28, 2024Inventors: Atsuki OHIRA, Eisuke HORII, Hiroyuki IWASAKI, Masayuki UENO, Shotaro YAMAZAKI, Takashi SHIMADA, Tomoaki KOTAKI, Yohei SATO

Publication number: 20240075915Abstract: A vehicle brake system includes a first fluid pressure generating device for generating a fluid pressure according to a brake operating amount, a second fluid pressure generating device for generating a fluid pressure by moving a piston with an electric actuator, and a switching valve switchable between a first state allowing communication between the first fluid pressure generating device and a vehicle behavior stabilizing device and a second state allowing communication between the second fluid pressure generating device and the vehicle behavior stabilizing device. A control device places the switching valve in the second state during execution of automatic brake control, and places the switching valve in the first state when a predetermined abnormality occurs in the vehicle, except that the control device places the switching valve in the second state when an abnormality including inability of the second fluid pressure generating device to generate the fluid pressure occurs.Type: ApplicationFiled: September 5, 2023Publication date: March 7, 2024Inventors: Eisuke HORII, Hiroyuki IWASAKI, Yohei SATO, Tomoaki KOTAKI, Masayuki UENO, Shotaro YAMAZAKI, Atsuki OHIRA

Patent number: 5843626Abstract: In a method for manufacturing a master disc for optical discs, patterns to be displayed on the disc are classified into a main object and a background. The background is commonly assigned as the background pattern for glittering rainbow colors by diffracted light reflected from dummy pits of diffraction gratings or a hologram. The main object is individually assigned as the main object pattern of a diffused reflection portion or mirror surface. The manufacturing method comprises one group of steps for forming the common background pattern and the other group of steps for forming the individual main object pattern in the common background pattern. A development substrate for the master disc is formed by using a mask disc in a first light-exposure of a photoresist layer thereof and by using a displaying-pattern mask in a first light-exposure of the photoresist layer. The individual main object pattern is drawn in the common background pattern of the master disc by using a laser-marking or an etching.Type: GrantFiled: April 16, 1996Date of Patent: December 1, 1998Assignees: Pioneer Video Corporation, Pioneer Electronic CorporationInventors: Minemasa Ohta, Hiroyuki Ohira, Nobuki Yamaoka, Yutaka Murakami
