Title: Electric fan
Inventor: IWASE KOUJI
IPC: F04D29/44
Filed: 1978-02-06
Abstract: PURPOSE: To eliminate the peak sound three times as high as the fundamental frequency of an impeller by cutting diagonally the inlet of a diffuser vane and setting the length l of the cutting at l = (0.4W0.75)πd/3z (where d represents the outer diameter of the impeller and z represents the number of vanes).  
     CONSTITUTION: Diffuser vane 3a is placed in front of partitioning plate 3 and in the external radial direction of impeller 2. Return guide vane 3b is projected in the back of partitioning plate 3, and a concentric gap is formed between partitioning plate 3 and fan casing 1. To send cooling air from the outside of impeller 2 to electric motor 5, a fluid passage is formed. The radius of the inlet of diffuser vane 3a on the side of partitioning plate 3 is made small and that on the side of fan casing 1 is made large. The inlet is cut diagonally, and the length l of the cutting is set l = (0.4W0.75)πd/3z. By this, the peak sound three times as high as the fundamental frequency of impeller 2 is eliminated.

Title: Braking device for motor-driven vehicle
Inventor: ENOMOTO NAOYASU
IPC: B60L7/24
Filed: 1994-02-03
Abstract: PURPOSE:To ensure the safety of a regenerative braking system at the time of a failure, restrain wasteful consumption oil, and restrict the change in brake depressing characteristics when the braking mode is switched. CONSTITUTION:A branch pipe 8 is connected to the piping 24a at the outlet of a master cylinder, and a stroke simulator 9 is connected to the branch pipe 8 through a cut-off valve 10. When a regenerative braking system fails during braling operation, a by-pass valve 7 is opened. At this time, oil pressure Pm outputted from the master cylinder 4 is compared with a threshold value alphadetermined by a differential pressure reference value DELTAPr of a differential pressure regulating valve 6, and if Pm <alpha, a cut-off valve 10 is closed to interrupt the connection with the stroke simulator 9. When trouble occurs in state where braking is not applied, the cut-off valve 10 is closed independently of the oil pressure Pm.

Title: Surface heat emitting body
Inventor: KUNIMATSU SHUJI
IPC: H01C7/02
Filed: 1988-01-21
Abstract: PURPOSE:To simplify the whole configuration, facilitate handling, and suppressing the cost by connecting a surface shaped heat emitter body, which emits heat with supply of current, in series to a member having positive thermal factor characteristic. CONSTITUTION:A surface-shaped heat emitter body 1 emitting heat with supply of current is connected in series with a member 2 having positive thermal factor characteristic. Accordingly, even though this is a one in which the temp. of the heat emitter body 1 is raised by means of current supply to the heat emitter body 1 through the positive thermal factor member 2, the electric resistance value increases quickly according to the positive thermal factor when the temp. of the positive thermal factor member 2 has risen into the set temp. range in accordance with the positive thermal factor characteristic of the member 2 to suppress the current supply amount to the member 2, and consequently current supply to this surface-shaped heat emitter body 1 is decreased, and further temp. rise of the heat emitter body 1 is suppressed. In this manner, the temp. control of the heat emitter body 1 is conducted at the positive thermal factor member 2. This simplifies the whole construction, facilitates the handling, and suppresses the cost.
