Title: Method of controlling amount of cooling water according to tempeature of cooling water during foam molding
Inventor: SUGAWARA TOSHIO
IPC: B29C44/60
Filed: 1980-06-13
Abstract: PURPOSE:To prevent cooling molds from being cooled excessively in a cooling step during the foam molding, by automatically changing the air pressures for delivering cooling water so as to control the flow rate of the cooling water according to the detected water temperature. CONSTITUTION:The foaming molds comprises a core mold 10 and a cavity mold 20 for producing a component 90 from a material delivered from a material feeder 80. In the cooling step, cooling water is jetted from cooling water pipings 13, 23 in prescribed amounts. However, since the cooling water is recovered into a pool or the like, and is used again, the temperature thereof tends to rise gradually. The water temperature is detected by a temperature sensor 60 to open any one of magnet valves 101, 102, 103, 201, 202, 203 through a control panel 70 so that air pressure is applied to tanks 100, 200 to jet cooling water. As the predetermined pressures set by pressure adjusting valves 111, 112, 113, 211, 212, 213 are in three steps respectively, the amounts of cooling water to be introduced can be changed in three steps.

Title: Watch using sollar cell
Inventor: OOTAKE TSUTOMU
IPC: G04C10/02
Filed: 1978-07-04
Abstract: PURPOSE:To enable to charge efficiently at a wide variety of illumination area, by changing the connection of sollar cells depending on the brightness at external place. CONSTITUTION:The external brightness is detected with the photo electric element and output is produced via the inverter. The output phi is given to each gate of TR602, 603, and 604. When this signal is at high level(external place is at high intensity of illumination), TR602 and TR604 are turned on TR603 is turned off, to cause the sollar cells 601a and 601b in series connection into parallel connection. Inversely, in case of low level(external place is lower intensity of illumination), the sollar cell blocks 601a and 602b are changed into series connection. Thus, by increasing the number of series stages at lower intensity of illumination, and performing parallel connection at higher intensity of illumination, effective number of series stages is reduced to perform efficient charging.

Title: Intake secondary air feeder for internal-combustion engine
Inventor: KAWANABE TOMOHIKO
IPC: F02M23/04
Filed: 1985-04-16
Abstract: PURPOSE:To prevent the deterioration of operation performance and engine stall due to the over-lean state of air-fuel ratio by carrying out the air-fuel ratio control in the use of only the duty ratio range in which the flow rate of the secondary air continuously varies. CONSTITUTION:When the output-valve opening time TOUT calculated by an electromagnetic opening/closing valve 9 is over the upper-limit valve opening time TOUTH or below the lower-limit valve opening time TOUTL which is set according to the operation parameters such as engine revolution speed Ne and intake absolute pressure PBA, the opening/closing valve 9 is opened by the upper-limit valve opening time TOUTH or the lower-limit valve opening time TOUTL in one duty cycle. Therefore, the air-fuel ratio control in the use of only duty ratio range in which the flow rate of the secondary air supplied into the engine continuously varies is permitted. Since the duty ratio does not become the value close to 100%, the over-lean state of the air-fuel ratio of the supplied mixed gas can be obviated, and deterioration of operation perfor mance and engine stall can be prevented.

Abstract: PURPOSE:To previously reduce the catching caused by the friction of an opening/ closing lid with a tape due to the instantaneous opening thereof and to prevent the tape from being damaged by opening the opening/closing lid by specified amount in the middle of operation for inserting a cassete in a cassette loading device. CONSTITUTION:After the locking of the opening/closing lid 6 is released corresponding to the insertion of the cassette 1 (in a direction shown by an arrow), the reel base of a VTR device and a reel hub 3 in the cassette 1 are engaged, so that the lid 6 is gradually opened along the inclined surface 14 of a lid opening member 12. Therefore, even though one end of the tape is pulled to the inner surface 15 of the opening/closing lid by frictional force with the lid 6, the lid 6 is not instantaneously opened by the specified amount from a fully closed state manually or by a motor driving means as in the conventional manner. Therefore, the tape 2 is fully separated from the inner surface of the opening/closing lid. In such a case, the catching caused by the friction of the lid with the tape is previously reduced and the tape is prevented from being damaged.
